Festo VL/O-3-1/8-B Pneumatic valve

• Festo VL/O-3-1/8-B: High Flow 3/2-Way Pneumatically Actuated Valve
• Reliable G1/8 Classic Tiger Series Valve (Festo Part 7803)

Achieve high-speed, reliable control in your pneumatic automation systems with the Festo VL/O-3-1/8-B Pneumatic Valve (Part Number 7803). As part of the popular Tiger Classic’ series, this directional control valve is engineered for durability and high flow capacity in demanding industrial environments.

This valve functions as a 3/2-way monostable valve, meaning it has three ports and two switching positions, returning to its home position via a mechanical spring when the pilot signal is removed. It is pneumatically actuated and allows for operation in both normally open and normally closed  circuits.

Key Technical Specifications:

• Valve Function: 3/2-way, monostable (single-piloted, spring return).

   

• Actuation Type: Pneumatically actuated (external pilot air required).¹⁰

   

  Connections: Features G1/8 internal threads on all working and pilot ports.

   

• Flow Rate: Offers a high standard nominal flow rate of 500 liters per minute (500 liters/minute).

   

• Operating Pressure: Wide range from -0.95 bar (vacuum) up to 10 bar

   

• Pilot Pressure: Requires a pilot signal pressure between 1 bar and 10 bar

   

• Durable Design: Constructed with a rugged Die-cast Aluminum housing and seals

   

• Protection: Rated to IP65, offering protection against dust and low-pressure water jets.¹⁷

   

• Mounting: Versatile mounting options including direct through-hole installation or on a manifold rail.¹⁸

   

The Festo VL/O-3-1/8-B’s robust poppet valve concept and high flow make it ideal for quick cycling and reliable control of single-acting cylinders and pneumatic functions
