Check Valve

Check valves block the flow of fluid in one direction while permitting flow in the other.  This prevention of back flow can be an integral part of a circuit to maintain pressure, hold actuator postion or protect devices from reverse flow.  Simple check valves only permit flow in one direction while pilot operated check valves can permit reverse flow when released via a pilot signal.  All SMC check valves feature low cracking pressure in the normal flow direction.
