It’s fall and for some, still warm – but it won’t be long until another heating season begins. Some facilities are already seeing the restart of boilers, and so, I’ve decided to address a cold weather issue that often arises with industrial steam and water boilers this time of year: they don’t start. Is there anything worse than a service call at 3 AM in January when the temperatures outside drop to -20°C? Once you have eliminated each component in your boiler as a possible culprit to boiler failure and it comes down to a check valve sticking open or closed in your system, it’s time for a replacement.

Each boiler is unique in the way it is designed and your choice in replacement will be somewhat dependent on the specifications your system requires. Whether you have a liquid, gas or steam boiler, this introduction to DFT Inc.’s three most common check valves for HVAC service is sure to get you warmed up to a replacement valve.

Note: DFT also manufactures check valves for use in large industrial boiler systems. A complete guide can be found here.

 

BASIC CHECK VALVE

Basic-Check-(1)

This proven check valve is suitable for a wide range of applications and is extremely versatile due to its ability to work at various pressures and temperatures. The Basic Check Valve can be made in different grades of stainless steel and is available from ¼” – 2 1/2” line sizes. The basic check can be used in installations requiring a CWP of 450-6,000 psi. DFT also manufactures the Basic Check with higher cracking pressures, from 2-40 psi. While the Basic Check is versatile, be sure to reference DFT Inc.’s full Catalogue for certain restrictions.

 

SCV CHECK VALVE

The most common check valve for use in steam applications, the SCV is also commonly used with liquid and gas. It uses the same trim as the Basic Check, in a durable body made of either 316 stainless steel, Alloy 20 or Hastelloy alloys with either FNPT or socket end welds. DFT SCV’s are available for ½”-3” pipe sizes and either 750 or 3,600 CWP. The SCV-R (Restrictor Check) is designed for higher cracking pressures than the standard SCV check valve. For a more simplified and flanged version of the SCV check valve, available in ASME Class 150 and 300, see DFT’s DLC check valve.

 

FBC CHECK VALVE

If you have an existing system with limited space – check this little space-saver out. The FBC “insert wafer” check valve is designed to be installed between two flanges and uses the same proven technology as the Basic Check valve. Though small, the FBC is made to last with stainless steel construction and a well-protected spring, not to mention the FBC can withstand temperatures up to 232°C (450°F). The FBC check valve works with schedule 40 pipe in the most common sizes 1”-4”, pressure class 150/300.

 

DFT Check Valves Used Extensively in HVAC

The simplicity and durability of DFT Valves has been proven since the original design dates back to the 1940’s and remains unchanged to this day. The non-slam, spring-assisted design prevents  reverse flow and virtually eliminates water hammer in your system. All of DFT’s check valves are capable of water-tight shutoff, are easy to maintain, can be installed in any direction and are built to last. Our distributors and end-users tell us that “they last too long” and regularly comment on their unsurpassed design and efficiency. If you would like to learn more about DFT check valves for industrial steam, water or HVAC, let us know, we’re here to help.

Fugitive emissions are a red hot topic right now – and for good reason. With ever-increasing environmental awareness, leakage and how to prevent and reduce leaks should be on everyone’s mind. As a gasket manufacturer, it is Triangle Fluid Controls job to design, develop and educate end users on products that can help them meet upcoming low emission regulations.

Common class 150# flanges are well known as a stubborn culprit when trying to seal flanged connections – particularly 3” and 8” lines sizes.  In the case of 150# flange design, an installer cannot apply enough load to the gasket due to either bolting, flange or material constraints. Another consideration is that with full face (FF) gaskets, you are trying to seal about 2-3 times the area of a ring gasket for raised-face (RF) flanges. You might ask,

 

“If I can’t apply more load to the gasket, how can I increase gasket load stress?”

 

Although it is case-by-case scenario, you have two options:


1) Reduce gasket sealing area

2) Use a controlled swell gasket material to intensify gasket stress after installation

Continue reading to determine the best option for your application.

 

 

Option 1: Reducing Gasket Area

pressure

Reducing the gasket area is extremely effective and usually one of the easiest ways to increase gasket load, when not enough load can be applied to the gasket. Remember that Pressure= Force/Area, so if we can decrease the area, the pressure (in this case the seating stress) will increase. Specifically, the Durlon RCA (Reduced Contact Area) gaskets and Durlon PTFE Step Ring gaskets are designed based on this concept. Both types of gasket are fairly unique, even though they reduce gasket area so that the gasket stress is increased. Durlon RCA type gaskets are ideal for full face (FF) flanges and FRP piping that require a tight seal, however, they cannot handle high bolt loads generally required for fugitive emissions or critical sealing applications. The skeleton of the RCA gasket resembles that of a full face (FF) one, except a large portion of the non-critical gasket area is removed for optimal sealing performance.

Front View - FF vs RCADurlon 9000 Step Ring gaskets are like a ring gasket, except a portion of the sealing area is reduced by machining it on a CNC lathe from one piece of material. Traditionally, these type of gaskets are manufactured by laminating two gaskets of a thinner gauge and various size together with an adhesive. Aggressive chemicals, such as sulfuric acid, can quickly eat away at the adhesive after installation, which can lead to a premature leak path. PTFE Step gaskets are commonly found in sulfuric acid plants, and applications for PTFE Step Rings include 150# raised face (RF) (Floating) Lap Joint flanges, as well as MondiTM ductile iron sulfuric acid piping.

Step Gasket

 

Option 2: Controlled Swell Gasket Material

 

In cases where the gasket area is already minimal and cannot be changed by design, or if reducing the gasket area simply isn’t enough, selecting a controlled swell material is a great option. These types of material really shine in low load applications that involve oil and water. Once the gasket is installed, the material swells when it makes contact with oils, fuel or water, which increases gasket thickness. As the material begins to “swell”, the gasket starts to expand, exerting force in both directions, against the flanges. Imagine a Belleville washer being compressed: by design, it applies force in the opposite direction, over the entire gasket-media contact zone and not just the fastener point-load zone. In theory, this is what a controlled swell material is doing. Durlon DuraSwellTM 7760 is a prime example of how choosing a high performance sealing material can negate less than ideal gasket sealing loads and still achieve a tight low to zero emissions seal.

Model

 

Conclusion

 

So, can low stress sealing applications meet fugitive emissions requirements? My answer is absolutely. As always, I recommend contacting your gasket manufacturer and providing all of the necessary application details. This will allow a specialist to recommend the proper material and installation methods to ensure the best performing sealing device for your specific needs.

 

Until next time, stay safe out there, and keep the fluid between the pipes!

Durlon® introduces fresh products with tighter sealing capabilities at low pressures that can actually help to protect your industrial system.

 

Durlon® Sealing Solutions, a leading name in premium PTFE and semi-metallic gaskets, introduced its newest line of sealing technology, dubbed “Durlon® iGuard™” Flange Isolation and Sealing Kits. Conveniently packaged to contain all necessary components to tightly seal, electrically isolate, and effectively control corrosion of mating metallic parts, the end result is a greatly reduced risk of leakage or system failure in severe services such as gas, acids and other aggressive chemicals or media, ranging from cryogenic to high temperatures.

 

Each kit consists of a gasket, isolating and backing washers, as well as isolating bolt/stud sleeves. Gasket selection can be made from a wide variety of materials to best suit the sealing and performance needs of each application. In gaskets with phenolic or glass carrier rings, a “double-ogee” sealing element provides a reliably concentrated unit load on the flanges using the lowest torqueing conditions possible. Gaskets are available in four different flange facing types and are able to meet all international piping sizes and dimensional standards.

IGuard 9000 sm

      Pictured: Durlon® iGuard™ 9000.

Particularly useful for industry professionals in the Oil & Gas, Chemical, Water/Wastewater and other process industries, the user simply lays the sealing element on the flange face. As the sealing element is compressed against the flange, any tiny gaps between the mating flange and sealing element become filled. This movement provides the end user with a tighter seal, despite potentially lower pressures, with the added ability to isolate parts. The tri-directional movement of the sealing element provides better elastic recovery over time, as bolt loads relax and pressure/temperature cycles occur.

Gas problems? No need to raise a stink!

May 31, 2016
By: Bruce Ellis

 

If you work in natural gas processing and refrigeration, chances are you know the demands of storing and transporting gas. Compared to fluid sealing and discharge, the media flow isn’t steady, instead, gas “pulses” (through a pipeline) from a reciprocating compressor. This pulsating flow created by the compressor causes the discharge valves to chatter, and while the sound may not be high on your daily list of concerns, the resulting wear or damage to your check valve and downstream components can eventually lead to costly headaches. With the ever increasing global demand for natural gas, issues with check valves and piping systems after installation of a reciprocating compressor is something we see occurring more frequently.

 

The problem: an ineffective check valve for gas applications.

 

With natural gas production set to double by 2017 (U.S Energy Information Administration), producers must ensure that their systems are designed with quality parts. While sourcing quality equipment can be time consuming and result in large up-front costs, having the right parts installed in your system will ensure less time spent on maintenance, downtime, and fewer future costs. Ineffective discharge valves are more likely to create issues and suffer undue wear than using a check valve built with a damped design to control the valve’s moving parts. It’s not unheard of to learn of parts that have broken off of valves, damaging downstream components which may cause system failure.

 

 

Built specifically for gas applications, DFT’s PDC check valve is a world-class solution found in oil refineries, gas pipelines, as well as storage and pump stations. Its pulse dampening chamber keeps the disc stable and in place (see below video). The PDC is also self-sizing, meaning it can handle different pressures and flow rates, without creating an issue or suffering undue wear. This flexibility extends the life of the valve. As an added benefit, the PDC can protect downstream equipment from damage that could be attributed to other types of valves if they fail.

 

The PDC check valve is manufactured to meet industry standards and can be built and tested to meet your company’s specifications. Available in various sizes and pressure classes, it can be manufactured using various metals, and is available with flanged, butt weld, or RTJ ends.

On March 30th, 2016, Belleville ON gasket manufacturer, Triangle Fluid Controls Ltd. (TFC) offered a facility tour in coordination with Canadian Manufacturers & Exporters (CME), through the SMART Program – a collaboration with Canada’s Federal Economic Development Agency focusing on Ontario manufacturing. The insightful manufacturing tour welcomed members of the local community, industry peers, local policy makers, media and members of the CME to visit TFC, to learn about internal processes, manufacturing procedures, understand TFC’s business model and gain knowledge about reaching and exporting to markets around the globe.

The tour provided a free platform for TFC to openly share knowledge, information and expertise amongst business leaders, community partners as well as how to increase productivity, discuss TFC’s information & communication technologies and better monitor energy management and environmental performance. As Tom Gunsinger, C.E.T and President of Bel-Con Design-Builders Ltd. put it, “I know [the visitors] appreciate the sharing of information amongst peers – it helps everyone to strengthen and support each other instead of being adversarial – it’s great.”

“This [CME tour] allows Bel-Con to open up the doors through TFC to other manufacturers and others in the industry to see exactly what goes on at TFC and in the city of Belleville. TFC is one of Belleville’s hidden gems!” said Alan D. Langabeer, Business Development at Bel-Con Design-Builders Ltd.

Also in attendance was Todd Smith, MPP of Prince Edward-Hastings. “A lot of times you drive through the industrial park and see the buildings, yet have no idea what goes on inside – what the products are; how many people work there; the level of technology that’s involved – this was a good education.”

“It’s always interesting to see how complex every little project is,” he adds. “Knowing that a Belleville company is involved in massive projects around the world is pretty neat and that this type of technology, expertise and manufacturing capabilities are happening right in our own backyard.”

When asked about his thoughts on the facility, Bill Saunders, CEO of the Belleville Chamber of Commerce replied, “I think this is the classic example of a phenomenal success story that’s flown under the radar.  I don’t think the community and policy makers truly understand what happens here, the contribution to the community, the challenges they face and the opportunity to leverage this success with other businesses.”

If you are interested in a tour of Triangle Fluid Controls contact Mike Shorts at mike@trianglefluid.com or call our global headquarters at 1-866-537-1133.
