3/2 Push Button Valve, Monostable NC, Spring Return | Aignep

The AIGNEP 01VT03NC03 Pull Valve, 3/2-Way Monostable NC with Spring Return is a manual compressed air control valve actuated by a pull handle, designed to manually, quickly, and safely activate or deactivate pneumatic circuits. In the rest position, it is Normally Closed (NC) — the air passage is blocked. Pulling the handle opens the air passage to the circuit. Upon release, it automatically returns to the closed position by spring. Unlike the mechanical tappet valve (01VV), this one is activated by direct human action (manual pull handle). 1/4" BSPP connection. Manufactured in Italy by AIGNEP.

Types of Manual Actuation Series 01V — Which to choose?

• Pull Handle (01VT — this valve): Actuation by pulling a handle. Direct manual operation by the operator. Ideal for control panels and workstations
• Mechanical Tappet (01VV): Actuation by physical contact of a part or mechanism. Ideal for automatic limit switches
• Solenoid (01VS): Electrical actuation by PLC. Ideal for automation without human intervention

Principle of Operation

• Rest Position (NC): Air passage blocked — the pneumatic circuit is deactivated
• When pulling the handle: The air passage to the pneumatic circuit opens
• When releasing the handle: Automatic return to closed position by spring
• Monostable: Requires continuous operator action to keep the passage open

Applications

• Manual control of industrial pneumatic circuits from control panels
• Manual activation of pneumatic actuators in machinery and production lines
• Workstations where the operator manually controls air flow
• Pneumatic safety systems with manual emergency control
• Maintenance and testing of industrial pneumatic circuits
