S&S Newstar S-17766 Control Valve with Knob and Nut and Roll Pin -

REPLACEMENT FOR BENDIX PP-8
Delivery: (2) 1/8: PT
Supply: 1/8" PT
Exhaust: 1/8"

Our Push-Pull dash control valves include a pressure sensitive on/off control valve that immediately returns the valve to the exhaust position when the air supply pressure drops below the required minimum. Our control valves are tested for proper leak down detection, automatic "pop" pressures, and proper crack pressures.

The PP-8 is a manually operated on/off control valve. Unlike others, it is not automatic and will remain in the position it is placed in, regardless of delivery or supply pressures. It is commonly used to control the tractor parking brakes only on "121" air brake systems.
