WANVALVE Pneumatic 3-Piece Flanged Ball Valve WP11-3PS-F

The WANVALVE WP11-3PS-F Pneumatic Actuated 3-Piece Flanged Ball Valve delivers superior flow control and automation efficiency. Featuring a full port design, this valve minimizes pressure drop and enables unrestricted flow through the system. Built with precision-engineered stainless steel (SS304, SS316, or SS316L), it offers outstanding resistance to corrosion and mechanical wear, ensuring optimal reliability in demanding environments.

Working Principle

The pneumatic actuator of this flanged ball valve operates by converting the energy of compressed air into mechanical motion. When air pressure is applied to the actuator chambers, it rotates the valve stem through a 90° turn, allowing the full port ball to open or close the flow path. The double acting option provides air supply for both opening and closing, ensuring precise control and fast response in automated systems.

Design & Features

This pneumatic actuated ball valve integrates a high-performance actuator that uses compressed air to operate the valve with smooth and consistent torque. The actuator supports both single acting and double acting configurations, allowing flexibility for different control setups. Its ISO standard mounting pad makes installation compatible with various actuator systems and accessories.
The 3-piece flanged ball structure simplifies maintenance, while the socket weld options provide secure and leak-proof connections in specialized installations.
