GENERAL
The H-400 Series is a compact design for instrumentation panels and systems, which provides an accurate operating point. H-400 valves are normally closed. When differential pressure between the inlet and outlet is higher than the set pressure of the spring, the loaded poppet will move backwards and will enable a free passage of flow through the valve. For vacuum applications please select H-400HP series.

H-400 SERIES ORDERING INFORMATION
TESTING
The H-400 valve designs have been tested for Proof and Burst. Every H-400 valve is factory tested for proper assembly, by leakage detection at 1000 psig (68 bar) for 10 seconds. Every H-400 valve is factory tested for functionality at the relevant cracking pressure, 5 cycles each.

GENERAL
The H-400HP Series is a compact, robust and heavy duty design for high-pressure (up to 6000 psi) instrumentation panels and systems, which provides an accurate operating point. H-400HP valves are normally closed. When the differential pressure between the inlet and the outlet is higher than the set pressure of the spring, the loaded poppet will move backwards and provide a free passage of ow through the valve. H-400HP CNG is specially designed for the CNG/NGV

COMPACT ONE PIECE FIXED CRACKING PRESSURE CHECK VALVE
GENERAL
The H-400OP Series is a compact one-piece design for moderate pressure (up to 3000 psi) instrumentation panels and systems, which provides a xed operating point. H-400OP valves are normally closed. When the differential pressure between the inlet and the outlet is higher than the set pressure of the spring, the loaded poppet will move backwards and provide a free passage for ow through the valve. For vacuum applications, please select the H-400HP series.
