GENERAL

The H400-HP Series is a compact, robust and heavy duty design for high-pressure (up to 6000 psi) instumentation panels and systems, and provides an accurate operating point. H400-HP 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 flow through the valve.

CLEANING & PACKAGING

HAM-LET H400-HP valves are treated with HAM-LET Passivation, Cleaning and Packaging (Procedure 8075). HAM-LET H400-HP Valves with face-seal end connections are treated with HAM-LET Oxygen Cleaning and Packaging (Procedure 8055). Oxygen Cleaning and Packaging for other end connections are available as an option.

TESTING

The H400-HP valve designs have been tested for Proof and Burst. Every H400-HP valve is factory tested for proper assembly, by leakage detection at 1000 psig (68 bar) for 10 seconds. Every H400-HP valve is factory tested for functionality at the relevant cracking pressure, 5 cycles each.
