Cartridge Check Valve 3/4-16 UNF-2A
Compact cartridge check valve for smaller-bore manifold circuits and pilot-line applications. Free-flow passes from port 1 to port 2; reverse flow is blocked. Three cracking pressure options allow it to be tuned to the specific circuit requirements.
Its small body and standard UNF cartridge thread make it a practical choice where space is limited and a reliable, low-leakage check is needed.
