Air prep control valves shut off air pressure downstream when at rest and allow air to flow when activated. Manual valves are operated with a knob; solenoid-activated models are available as a standard shut-off valve, or with soft start (gradually increase air pressure downstream when energized) and dump (quickly relieve downstream pressure when de-energized) functions.
Pneumatic Control Valves
Category Selection
Norgren Excelon Plus 82 and 84 Series Air Manual Shut-Off Relief Valves
Excelon Plus 82 and 84 series lockable shut-off valves are available in a 3-way/2-position configuration with threaded exhaust and red knob. The full flow rotating ball valve and restricted 1/4" NPT exhaust port make it possible to add a silencer or pipe the exhaust away. The valve has a 'pop up' padlock feature, allowing the valve to be locked in the closed position for safety.
Features
- Downstream pressure is relieved when the valve is closed
- 1/4", 3/8", 1/2" and 3/4" PTF (FNPT - female NPT threaded ports)

Norgren Excelon Plus 82 and 84 Series Air Soft Start/Dump Valves
Excelon Plus 82 and 84 series soft start dump valves allow downstream pressure to gradually rise on initial start-up, before fully opening to deliver line pressure. The dump function allows the system to be exhausted quickly when required, particularly in the event of a power failure or emergency stop.
Features
- 24VDC solenoid valve with DIN 43650 Form C (8mm) plug
- High flow dump capacity
- 1/4", 3/8", 1/2" and 3/4" PTF (FNPT - female NPT threaded ports)
- Includes field wireable DIN connector

Norgren Excelon Plus 82 and 84 Series Air Control Valves
Excelon Plus 82 and 84 series control valves are helpful pneumatic system components. In the off position, the downstream system pressure is routed through the tapped exhaust port.
Features
- 24VDC solenoid valve with DIN 43650 Form C (8mm) plug
- High flow dump capacity
- 1/4", 3/8", 1/2" and 1/4" PTF (FNPT - female NPT threaded ports)
- Includes field wireable DIN connector

NITRA® Soft-Start / Dump Valves (ASD Series)
The three-way, two-position (3 threaded ports) design of these valves is used to gradually increase air pressure downstream when the solenoid is energized and to shut off upstream pressure and relieve downstream pressure when it is de-energized.
Provided with a mounting bracket for stand-alone applications, the modular design also enables easy field assembly with NITRA pneumatic filters, regulators and lubricators (using modular assembly brackets purchased separately).
Features
- 1/8", 1/4", 3/8" or 1/2" NPT port sizes
- 24 VDC or 120 VAC solenoid coil voltages
- 130 psi maximum operating pressure
- 11mm DIN style wiring connector with LED indication
- Modular design for easy field assembly with NITRA pneumatic filters, regulators and lubricators
- Mounting bracket provided for stand-alone applications
- 2-year warranty
Accessories
- T, L and U-brackets for assembly and mounting of NITRA air prep components
- AGP series gauge plates for replacement of integral pressure gauge with a larger pressure gauge or a pressure transmitter
