Product Details

New valve - Not remanufactured Genuine Bendix craftmanship Has 3/8" tubing push-to-connect fittings 1/4-20 threaded mounting holes The PP-DC park control double check valve is a push-pull, manually operable on/off valve with an integral double check. It is dashboard mounted and provides in-cab control of truck or bus parking brakes. Manually pushing or pulling the button will release or apply the parking brakes. The integral double check valve allows the PP-DC valve to receive supply air pressure from either, or both, the front or rear axle service reservoirs. The valve is pressure sensitive and automatically moves from the applied (over the road position) to the exhaust position (thus applying the parking brakes) if total system pressure (both front and rear axle reservoirs) drops below 20 to 30 psi.
