Hydrogen Valves

• All valves for hydrogen refueling applications are optimized for long service life
• Suitable for operation in the temperature range -40°C up to +85°C according to ISO 19880-3 and ANSI / SAE HGV 4.7
• Valve sizes from 1/4" up to 1"
• Pressure range up to 15.000 psi (1.050 bar)
• Special cleaning for use in hydrogen systems to avoid contamination
• Leakage test on seat and packing with helium at maximum operating pressure
• Specific selection of metallic materials to avoid hydrogen embrittlement
• Dynamic sealing elements for low leakage and long service life

Multi-Functional Dispenser Valve

This valve is to be used on the release side of the filling hose. The multi-porting  reduces the need for additional connections, saving space and reducing the risk of leaks.

The stem travel can be adjusted which directly effects the orifice. Hence the vent-down process can be optimized to reduce noise emissions.

The outlet check valve which is located downstream towards the vent line (stack) is integrated as well.

• Reliable normally open needle valve with 3" (75 mm) compressed air drive to be used for pressure release of filling line
• Double porting on left hand side eliminates need for Tee fitting
• Connection for rupture disk
• Check valve integrated on outlet
• Adjustable stem travel = adjustable orifice
• High leak integrity and compact integrated design
• Low wear because of optimal materials of construction
• Weep holes on connections for maximum safety

Hydrogen Cone Check Valve Series 21CC-H2

This check valve is specially designed for hydrogen applications. In contrast to conventional check valves, this valve uses a sealing cone in combination with a soft seal. As a result, the cone check valves impress with excellent sealing properties and a long service life.
