cartridge check valve

Ball Type Cartridge Check Valve is used to preferentially connect the cut-off oil circuit of the high-pressure oil circuit.The Ball Type Cartridge Check Valve consists of a steel ball that can seal against one of two adjacent seats, providing a path from the highest pressure signal to another function. When one inlet port is pressurized, the ball or poppet is forced against the opposite seat, blocking that inlet and providing a flow path to the outlet port.
