DE WIT VA7 Series Air-Piloted Pneumatic Valve - 5/3-Way

DESCRIPTION FOR PILOT-OPERATED VALVE SERIES VA7 (5/3 WAY - CENTERS)

The Series VA7 5/3-Way (Centers) Air-Piloted Pneumatic Valve is the heavy-duty line designed for robust control of medium- and long-stroke actuators and cylinders. By combining high flow capacity with the precise control of a 3-position valve, it becomes the ideal choice for the manufacturing industry and automated processes that demand safe intermediate stops and fast response through 100% pneumatic signals.

Key Features:

• Advanced Position Control (Centers): Its three center configurations (Closed, Open/Exhaust or Pressurized) provide full control over the piston in its rest state, vital for emergency stops or exact positioning.

• High Flow Capacity: Features optimized internal passages to move large volumes of air without drastic pressure drops, ensuring actuator force and speed.

• Intrinsically Safe Operation: Being actuated solely by air pilots (no electricity), it is ideal for zones with explosion risk, high humidity or heavy washdown.

• Flexible Mounting: Allows a direct individual inline installation or a centralized assembly using multiple bases (BM series Manifolds) for high-density circuits.

Technical Specifications:

• Function: 5/3 Way (5 ports, 3 positions with spring return to center).

• Center Configurations: Closed Centers (C), Open/Exhaust Centers (E) and Pressurized Centers (P).

• Actuation Type: Double Pneumatic Pilot.

• Body Sizes: 100, 200, 300 and 400.
