Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination. They’re often used in research sample systems, emission monitoring systems, and chromatography. Valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Outlet fittings are Swagelok® for a leak-free seal around hard metal tubing in high-pressure lines. Also known as instrumentation fittings, Swagelok® fittings are compatible with Parker A-Lok, Gyrolok, Bilok, and Tylok fittings. Valves come with a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.

Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.

Two-stage valves progressively reduce pressure over two steps for more consistent outlet pressure at all times. They’re often used in applications that require a constant outlet pressure regardless of the tank level.

OMB offers the complete range of high-pressure valves such as the solenoid tank valve (ERA 1) with the option of an integrated pressure regulator, the fuel receptacle, remote TPRDs and check-valves. The full range of products are developed in compliance with the major international Standards and Regulations such as EC 79/2009, HGV 3.1. HPRD-1, UL 2267 and IEC 62282.

Historically and currently, enormous amounts of hydrogen are needed for key industrial processes such as the manufacture of artificial fertilizers and steel. New H2 applications such as fuel cell vehicles would further increase future demand. To contribute to the energy transition, this hydrogen needs to be "green" instead of being derived from fossil fuels, i.e. without producing CO2 in the process.

This will require large hydrogen electrolyzers. These consist of several stacks of electrolysis cells. For safe operation, the individual stacks require protection against overpressure with safety valves.

The WITT safety valves AV 619 and AV 919 perfectly match the target pressure and temperature ranges of PEM and Solid Oxide electrolyzers. The opening pressure can be set accurately anywhere in range 5 to 500 mbar. The operating temperature can be anywhere up to 250°C.

Highly precise and reliable, the valves open when the set pressure is reached and safely protect workers and sensitive equipment from overpressure. Despite their small size, the valves allow high flow rates, making them also suitable for large installations.

The valves are available with the elastomers required for hydrogen, including EPDM or FFKM (also known as FFPM). WITT safety relief valves are oil and grease-free, can be installed in any position, and are available with various inlet and outlet connections and in different materials, including stainless steel or aluminum (AV 919). Optionally, WITT offer TÜV Certification of individual valves’ set pressures.

Hydrogen pressure valve for home use are suitable for home use. They are safe and easy to use as a hydrogen water maker, safe for both use and home use.

Hydrogen pressure valve for home use can also improve blood circulation. There is also a need for hydrogen therapy at home, such as a hydrogen pressure device for skin.

Hydgen pressure valves offer a stable and stable hydrogen pressure. They do not contain any hydrogen at all at the same time, as they are not applied to water or other metals.

To fulfill this potential, hydrogen vehicle and refueling infrastructure must be designed and built with high-quality materials in order to deliver leak-tight performance that will need to last for years or even decades. And not just any components are up to the task. The production and handling of hydrogen fuel comes with its own unique set of challenges, thus demanding a specific set of performance criteria from components throughout a hydrogen fuel system.

Valves—responsible for controlling the flow of hydrogen in vehicle or stationary systems—are a good example. How can you be sure you’re selecting and specifying a valve that delivers performance suitable for hydrogen service? Read on to find out.

All hydrogen valves should offer performance levels that meet those requirements. They should demonstrate leak-tight performance at the connection point and at their shutoff or regulation point, with the ability to withstand the necessary operating conditions inherent to hydrogen applications.

All connection points in hydrogen systems must be leak-tight. Any escaping gas can pose a safety risk, especially when end-users interact with a dispenser during refueling. Leaking gas in cars or storage systems is also wasteful.

And because hydrogen molecules are so small, they can in fact diffuse into lower-quality stainless steels. This phenomenon is known as hydrogen embrittlement. Over time, pressure can produce fissures in the material, which can become highly problematic in hydrogen service.

Ball valves are a common component found in hydrogen systems, used to start and stop the flow of hydrogen from one direction to the next. When selecting ball valves for hydrogen applications, it is important to look for stem seal designs that are highly resistant to wear. A good option may incorporate a trunnion-style ball with a direct-load design, which helps to enable leak-tight performance with every activation and shutoff. A bottom-loaded stem design can also reduce any potential stem blowout, offering enhanced safety.

When in doubt, your valve supplier should be able to help guide your selection. Applicable ball valves may offer 2- or -3-way functionality, different mounting options, and a range of flow coefficients depending on the needs of your system. Finally, look for good compatibility with fittings that are designed specifically for hydrogen applications.

Needle valves are used to make relatively fine adjustments in the amount of fluid flow. In hydrogen applications, some important considerations must be made when specifying them. Needle valves are typically all-metal in construction, requiring a large amount of force to seal properly. Such a force has the potential to deform the needle itself and possibly the seat, creating a potential hazard and requiring costly maintenance. Further, such required force typically necessitates the use of large air actuators to open and close the valves, which can take up to two minutes to fully actuate.

With these things in mind, it is important to look for needle valves that are made from high-quality 316 stainless steel that can resist deformation during repeated use. Also, keep in mind that not all needle valves are properly pressure-rated for common hydrogen applications (350/700 bar); choose a needle valve that is qualified for elevated working pressures. And like with ball valves, compatibility with other hydrogen-qualified components is a must.

Check valves perform essential safety functions in hydrogen compressors in refueling systems, controlling excess backflow in order to protect the end user. Compared with general service applications, hydrogen check valves must contend with a few things.

Most check valves incorporate springs—components that are typically made with strain hardened material that can be more susceptible to hydrogen embrittlement than high-quality 316 stainless steel. Additionally, vehicle fueling applications subject such valves to large, fast changes in temperature and pressure, creating elevated stress on the valve’s elastomer seals. With these things in mind, ball check valves are a more suitable option for hydrogen compressors. Material integrity and compatibility with other hydrogen components are important here, too.

The long-term viability of hydrogen mobility fuel market depends on the safety, reliability, and durability of vehicles and infrastructure. Selecting and specifying the right components for all hydrogen systems can help the technology meet its full potential over the long term.

They are also available with limit switches and solenoid valves. The single-acting actuators utilize a fail-safe feature: The Air-to-Open actuator closes the valve on loss of operating pressure, while the Air-to-Close actuator opens the valve on loss of operating pressure. These safety features are necessary in critical systems.Check Valves

Provide maximum filtration surface area for removal of contaminating particles from the fluid system. May be used in systems requiring high flow rates with minimum pressure drop. Available in nominal ratings of: 5, 10, 20, 40 and 100 micron.Regulating Valves

These Regulating Relief valves use a differential area poppet design with a high ratio between the seal and seat area for smooth control, repeatability and low deadband between crack and reseat pressure. The design also makes the control settings virtually unaffected by downstream outlet pressure.Hand Tools

Hydrogen Service’s castings are highly endorsed forRadiographic quality. The joints of Body, Bonnet, Cover and Stuffing box shall have low emission, so it shall be Helium leak tested as per ASME Section V (Detector probe technique)

Brinell hardness shall not exceed 200 BHN for Carbon steel and 225 BHN for Alloy steel. Charpy V notch impact testing is to be done for valve material of CS and AS.

During the construction of hydrogen valves, metals and non-metals must be compatible with hydrogen and must not be vulnerable to hydrogen embrittlement during further processing.

Based on a flexible modular system, we develop and supply control and switch valves for customer-specific requirements in mobile and stationary applications.
