Festo VSVA-B-P53E-D-D2-1R5L (Part Number: 566998) Solenoid Valve

The Festo VSVA-B-P53E-D-D2-1R5L (566998) is an industrial ISO-standard 5/3-way mid-position exhausted solenoid valve designed for high-flow pneumatic automation, machinery safety circuits, and multi-axis control. Built according to the ISO 5599-1 (Size 2) sub-base standard, this valve provides reliable directional control for double-acting pneumatic actuators.

Featuring a 5/3-way function with mid-position exhausted (normally unpressurized in center position), this valve releases pressure from both actuator ports when de-energized, allowing safe manual movement or emergency vent function during system stops.

Key Features & Benefits

• ISO Standardized Sub-Base Interface: Conforms strictly to ISO 5599-1 Size 2 for universal sub-base mounting, fast replacement, and modular manifold expansion.

• 5/3-Way Mid-Position Exhausted: Center-exhausted layout vents work ports 2 and 4 to exhaust when both solenoids are de-energized, ideal for safety and positioning circuits.

• High Flow Performance: Delivers up to 2300 L/min standard nominal flow rate, ensuring rapid cycle times for large pneumatic cylinders.

• Integrated LED & Central Plug: Features a central plug connection with integrated LED status indicators for clear operational diagnostics.

• Heavy-Duty Construction: Built with an aluminum die-cast housing, high-alloy stainless steel spool, and durable NBR seals to withstand demanding factory environments.
