| Directional Valve
QCV08-21 = Check valve =
A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
The QCV08-21 allows flow passage from ② to ①, while normally blocking flow in the opposite direction. The cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at ② to open to ①
