Product Description
The Festo VBOH is an elegant, ergonomically shaped hand slide valve featuring a non-overlapping design that eliminates pressure losses during switching, ensuring consistent system performance even under high flow and operating pressure conditions . This 3/2-way bistable manual shut-off valve is used for pressurising and exhausting compressed air systems, typically installed upstream of service units, for air blow guns, or for directly exhausting pneumatic cylinders .
Key Features & Advantages:
Non-Overlapping Design for Zero Pressure Drop: Designed to avoid overlapping switching positions, resulting in no pressure drop when shifting between states . This ensures uninterrupted flow in the open position and a complete seal in the closed position.
Extremely High Flow Rate & Operating Pressure: Boasts impressive pneumatic performance allowing for high compressed air flow with standard nominal flow rates from 777 L/min up to 7,691 L/min, and supports an operating pressure range of -0.95 bar to 12 bar .
3/2 Bistable Valve Function: Retains its switched position without needing a continuous pilot signal . This reduces energy consumption and is ideal for applications requiring stable open or closed positions.
Minimal Installation Effort & Ergonomic Design: The valve is designed for simple in-line or screw-in installation via female G-threads, minimizing assembly time . The slide mechanism is ergonomically shaped for comfortable and easy manual operation .
Robust Metal Construction for Durability: Features a high-quality housing made of anodized wrought aluminum alloy, providing moderate corrosion resistance (CRC 2) and robust performance in harsh operating conditions .
