Pneumatic Air Solenoid Spool Valves

Solenoid Spool Air Valves

Balanced-Spool Directional Control for Pneumatic Automation

Solenoid spool air valves direct compressed air to pneumatic actuators using a balanced spool design. The source range includes 3-way and 5-way configurations with port sizes from 10-32 UNF through 1/2 NPT, covering compact control circuits through larger machine-air requirements.

N3V and N5V valves are body ported and can also be mounted to an inline manifold system with up to twelve stations. A black hard-anodized aluminum body is listed as standard for durable industrial service.

Why Use a Spool Valve?

Spool valves are widely used for directional control because one compact valve can route supply and exhaust air to pneumatic actuators.
Manifold mounting can simplify machine plumbing and centralize multiple valve functions in one organized assembly.

Frequently Asked Questions

What is a solenoid spool valve?

It is an electrically actuated directional valve that uses a sliding spool to route compressed air between supply, work and exhaust ports.

What configurations are available?

The source range includes 3-way and 5-way versions.

What port-size range is listed?

The source description lists sizes from 10-32 UNF through 1/2 NPT.

What does balanced spool design mean?

A balanced spool arrangement is designed so supply pressure has less influence on the force needed to shift the spool, supporting consistent directional switching.

Can these valves be mounted on a manifold?

Yes. The source description states that they can be mounted to an inline manifold with up to twelve stations.

What body material and finish are listed?

The source description lists aluminum construction with a black hard-anodized finish.

Where are spool valves commonly used?

They are commonly used to control pneumatic cylinders and actuators in automated machinery.

How do I choose the correct spool valve?

Match the number of ways, port size, flow, pressure, actuator function, electrical requirements and manifold arrangement to the machine.
