HAM-LET H-400HP-SS-L-8MM1PSI is an instrumentation check valve for one-way flow control in small-bore tubing systems. This inline spring valve uses a poppet check mechanism to help prevent reverse flow in high-pressure service. Specified media includes chemicals, gas, oil, and water; verify material compatibility for the intended application. It features 8 mm Let-Lok x Let-Lok connections, a 316 stainless steel body, and a 1 psi cracking pressure.
