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.


BACK PRESSURE

Maximum allowable back pressure is rated to 1000 psi (69 bar) for 1/4,200 psi (14 bar) for 3/8 to 1". For higher back pressure please select valve from the H-400HP Series.
