Festo VSVA-B-B52-H-A2-1R2L (Part Number: 534776) Solenoid Valve

The Festo VSVA-B-B52-H-A2-1R2L (534776) is an industrial-grade 5/2-way bistable double solenoid valve built to the international ISO 5599-1 (Size 1) sub-base standard. Designed for robust performance in automated machinery, this valve delivers high pneumatic flow in a standardized, modular footprint.

Featuring a 5/2-way bistable (impulse) function, the valve maintains its switched position even during electrical power disruptions until a counter-signal is applied to the opposite solenoid coil. Operating on a 24V DC supply with an integrated LED status indicator, it provides dependable control for double-acting pneumatic actuators.

Key Features & Benefits

• ISO 5599-1 Size 1 Standard Interface: Fits universal ISO sub-bases and manifold blocks for easy interchangeability and system expansion.

• 5/2-Way Bistable Operation: Double solenoid mechanism holds position without continuous electrical power, offering energy efficiency and process safety.

• High Flow Rate: Delivers up to 1100 L/min standard nominal flow rate for fast actuator speed and system productivity.

• Central Plug & Visual LED: Central electrical connection standard (1R2L) equipped with an integrated LED indicator for real-time status diagnostics.

• Industrial Ingress Protection: Rated IP65 to resist dust ingress and low-pressure water jets in harsh plant environments.

• Manual Override: Built-in non-detenting/detenting manual control for effortless commissioning and valve testing.
