●液控單向閥是非調節的開關閥僅使用負荷鎖固，因此不提供流暢的運動控制。
●允許經一單向閥自由流通由2口到1口，反流封閉直到一正比于負荷壓力在3口打開才由1口流到2口。
●Pilot to open check valves are non modulating on/off valves used for load locking only and do not provide smooth motion control.
●They allow free flow from port 2 to 1 then block reverse flow until a pilot pressure directly proportional to the load pressure is sensed at port 3 enabling a pilot a pilot piston to push the poppet off its seat.
