Frequently Asked Questions

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

A HAM-LET poppet check valve prevents reverse flow in instrumentation and process lines. It is used in chemical, petrochemical, and gas systems where a compact, inline valve with FNPT connections is required. The 316 stainless steel construction provides corrosion resistance in demanding environments.

What are the specifications of the HAM-LET H-410-SS-N-3/4"-1/3 PSI check valve?

This HAM-LET check valve has an inline valve body with 3/4 in FNPT x FNPT connections. The seat material is 316 stainless steel, and the valve body is also 316 stainless steel. The manufacturer part number is H-410-SS-N-3/4"-1/3 PSI. It is a poppet-type check valve for instrumentation applications.
