Check valve with ball for hydrogen (901021-103)

EV HYDROGEN® check valve with ball for hydrogen.

Item number: 901021-103

To prevent reverse flow and where a tight shut-off is not mandatory, EV HYDROGEN® ball check valves are a must. The ball check valves are designed with a floating ball, and a cradled seat. The design gives a full flow around the ball which minimizes the pressure drop.

Design pressure: 1.050 Bar / 15.000 Psi
Maximum working pressure: 1.050 Bar / 15.000 Psi
Temperature range: -60°C to +200°C.
Connections: NPTF
Opening pressure: 2 Bar/ 29 Psi.

EV HYDROGEN® ball check valves comply with Pressure Equipment Directive (PED) 2014/68/EC.

Check valve with ball for hydrogen (901020-67)

EV HYDROGEN® ball check valve for hydrogen.

Item number: 901020-67 9/16

When a high quality directional flow control is neccessary, EV HYDROGEN® metal seat check valves are mandatory.
It provides a semi-tight shut-off for hydrogen where an O-ring type check valve is not an option due a demand of long life durability rather than 100% tightness.
