Frequently Asked Questions

What is a HAM-LET poppet check valve used for?

A HAM-LET poppet check valve prevents reverse flow in instrumentation systems. It is used in high-pressure fluid and gas lines where one-directional flow is critical, such as in chemical processing, oil and gas, and power generation. The inline body design with Let-Lok® connections ensures leak-free performance in demanding industrial applications.

What are the specifications of the HAM-LET H-400HP-SS-L-1"-25 PSI check valve?

This HAM-LET check valve has a 1 in pipe size with an inline valve body and Let-Lok® x Let-Lok® connections. It features a poppet design with FKM seals and is made of stainless steel. The manufacturer part number is H-400HP-SS-L-1"-25 PSI. It is designed for instrumentation systems requiring reliable backflow prevention.
