DESCRIPTION:
A screw-in, cartridge-style, hydraulic check valve for use as a blockingor load-holding device.
The QCV12-20 allows flow passage from ① to ②, while normally blocking oil flow in the opposite direction. The cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at ① to open to ②
