| Directional Valve
QCV10-21 = Check valve =
A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
The QCV10-21 allows flow passage from ➁ to ➀, while blocking flow from ➀ to ➁. The cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at ➁ to open to ➀
