Ham-Let H-400 Series Check Valves Valves - Hydraulic & Pneumatic

316 St.St. and Brass construction
Moderate Pressure Characteristics up to 3000 psi (206 bar)
Compact Design
Variable fixed cracking-pressure springs
HAM-LET LET-LOK, Male & Female NPT, and HTC Face-Seal Bead Ends.

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.

The H-800, one-piece Ball Valve series is designed for general service and instrumentation panels. Valve design enables low and high working pressure and accommodates a wide temperature range with high life cycle.
One-piece body design reduces possibility of shell leakage. The valves offer tight shutoff, long-life service and low operating torque.
HAM-LET H-800 Ball Valves are designed for fully open or fully closed operations only. After a period of non-operation, the valve's braking torque may rise.
