3-Way Air Pilot Valves

3-Way Pneumatic Pilot Control for Directional Air Circuits

3-Way air pilot valves use a pneumatic control signal rather than an electrical solenoid to switch compressed air flow. They are useful in machinery where a fully pneumatic control scheme is preferred or where an air pilot signal is already available.

The source range lists 3-way spool-valve configurations with port sizes up to 1/2 NPT, hard-anodized aluminum and stainless-steel body materials, and standard NBR seals with Viton or silicone options.

Pilot Valve Specifications

• 3-Way configuration
• Port sizes up to 1/2 NPT
• Hard-anodized aluminum and stainless-steel body options
• Maximum pressure listed at 20–125 psi(g) for spool-design models
• Response time listed at under 20 ms
• Temperature range 32–150°F / 0–65°C
• NBR seals standard; Viton or silicone options

Why Use Air-Pilot Control?

• Allows directional control without an electrical coil at the valve
• Useful in pneumatic logic and remote air-signal applications
• Fast switching and compact spool-valve construction

Common Applications

• Pneumatic logic circuits
• Cylinder and actuator control
• Packaging machinery
• Automated assembly
• Process machinery
