The In-line NPT Check Valve hydraulically locks a flow path by preventing return flow. The spring-loaded poppet opens to allow free flow in one direction and reseats once flow stops, holding the load. An optional orifice can be specified where a restricted return flow is required.
This NPT threaded version is rated to a working pressure of 760 bar and is available with cracking pressures of 0.35, 1.00, 2.00 or 4.50 bar to suit your system.
