Pneumatic Solenoid Valves provide directional control in compressed air systems where fast response, compact installation, and repeatable actuation are required.
The 3V Series is a 3/2 pneumatic solenoid valve with an aluminum alloy body, single-solenoid operation, and air return function for use in industrial automation and pneumatic control circuits.
This series comes in 1/8 inch to 1/2 inch female NPT sizes and features a normally closed configuration. It works well for compressed air applications that require dedicated supply, work, and exhaust paths.

Pressure, Temperature, and Media Fit
This series supports compressed air and low-flow pneumatic circuits that need directional control through supply, work, and exhaust ports. Additionally, the pressure range starts at 22 psi, so it suits systems with stable available air pressure better than very low-pressure pneumatic service.
The valve operates within a temperature range of -4 to 158°F. However, it does not permit use in applications below freezing. That line matters and should stay visible on the live page because it filters out a bad-fit use case early.
Dimensions
The 3V Series fits compact pneumatic assemblies, manifolds, pilot circuits, and machine-mounted control points where overall body length and installation space matter.
