STC QE N3/8 Quick Exhaust Valve 3/8" NPT x 3/8" Bore NPT

Quick Exhaust Air Valve Operation:

The Quick Exhaust Valve has three connecting ports: a pressure port & an exhaust port on opposite ends of the valve, and an outlet port on the top of the valve. When air pressure is applied to the pressure port, an internal check valve piston allows air to move from the pressure port to the outlet port. When the air pressure is removed from the pressure port, the internal check valve piston allows air to exhaust from the outlet port to the exhaust port. The Quick Exhaust Air Valve is designed to allow air to be quickly exhausted from an air reservoir or an air cylinder to achieve higher cycle speeds.
