Pneumatic 5/3-Way Valve, Closed Center, Spring Return | Aignep

The AIGNEP 01VP07OC03 Pneumatic Actuation Valve, 5/3-Way Closed Center with Spring Return is a directional valve from the 01V Series, actuated by pneumatic pilot with three positions: advance, retract, and locked center position (closed center). In the center position, all ports are blocked, holding the actuator fixed in its intermediate position. When the pilot signal ceases, it automatically returns to the center position by spring. It is the most advanced configuration of the 01V Series, ideal for applications requiring precise actuator stop and lock in an intermediate position. Compatible with 01V Series manifold. Anodized aluminum body, nickel-plated spool, NBR seals. Operates up to 10 bar. Manufactured in Italy by AIGNEP.

01V Series Configurations Comparison — Which to choose?

• 5/2 Monostable (01VP050003): 2 positions, spring return. Simple control of a double-acting cylinder with safe return
• 5/2 Bistable: 2 positions, pneumatic memory. Maintains position in case of signal loss
• 5/3 Closed Center (01VP07OC03 — this valve): 3 positions, center position blocks all ports. Ideal for precise actuator stop and lock in an intermediate position

Closed Center Operation

• Pilot signal A: Valve in position 1 — actuator advance
• Pilot signal B: Valve in position 2 — actuator retract
• No signal (center position by spring): All ports blocked — actuator fixed in intermediate position
• Advantage: Allows stopping and locking the actuator at any intermediate point of its travel

Applications

• Control of double-acting pneumatic cylinders with stop and lock in an intermediate position
• Systems where the actuator must stop and remain fixed when the signal ceases
• Pneumatic circuits without PLC or electricity at the control point
• ATEX zones or explosive environments requiring locking in an intermediate position
• Precision pneumatic positioning machinery
• Mounting on 01V Series manifold for pneumatic control units
