HAM-LET H-400-SS-L-10MM-1PSI is an instrumentation check valve for one-way flow control in small-bore tubing systems. It uses an inline spring, poppet-style mechanism with a fixed 1 psi cracking pressure to restrict reverse flow in lines carrying compatible chemicals, gas, oil, or water. The valve has 10 mm Let-Lok connections on both sides and a 316 stainless steel body.
