GENERAL
The H400 Series is a compact design for
instumentation panels and systems, and provides
an accurate operating point. H400 valves are
normally closed. When differential pressure
between inlet and outlet is higher than the set
pressure of the spring, the loaded poppet will move
backwards and will provide a free passage of flow
through the valve.
