GENERAL

The H-400 series is a compact check valve designed for instrumentation. H-400 valves are normally closed. When differential pressure between the inlet and outlet is higher than the set pressure of the spring, the poppet opens to enable a free passage of flow, through the valve. For vacuum applications, please select the H-400HP series.
