液控单向阀
A cartridge-style pilot-to-open
ball-type check valve
球阀式液控单向阀
SYMBOL
The valve allows flow from ② to ③ , while normally blocking flow from ③ to ② . Flow
will be allowed from ③ to ② when sufficient pressure is applied at ①．
The cartridge has a 3:1 pilot ratio, meaning that at least one-third of the load pressure
held at ③ is required at ① to open the valve.
当在②口的压力超过开启压力，②到③开启：在反方向，③到②关闭；
当在①口所需的液压力达到③口负载的 1/3 时，阀芯打开，③和②通，液控比为 3:1。
