WANVALVE WP11-3PS Pneumatic Actuated 3-Piece Threaded Ball Valve Full Port Stainless Steel
The WANVALVE WP11-3PS Pneumatic 3-Piece Threaded Ball Valve combines strength, precision, and automation to deliver stable flow control in modern industrial systems. Engineered with a full port passage and constructed from high-quality stainless steel (SS304, SS316, or SS316L), this pneumatic actuated ball valve provides minimal flow resistance and outstanding durability. Its 3-piece ball valve structure allows quick disassembly for maintenance or cleaning without removing the valve body from the pipeline.
Durable Stainless Steel Construction
The robust stainless steel body ensures superior resistance against corrosion and oxidation, even in demanding environments. Ideal for use with compressed air, gas, and chemical fluids, the valve maintains mechanical strength under high air pressure and temperature variations. The 3-piece design improves flexibility, making it easy to service seals or seats and extend the valve’s overall service life.
Advanced Pneumatic Actuation
Fitted with a high-performance pneumatic actuator, the WP11-3PS is available in double acting and single acting configurations. The actuator converts air pressure into precise quarter-turn motion, allowing stable and reliable automation. This makes it a preferred choice among engineers using pneumatic actuated ball valves for precision control, safety, and energy efficiency.

Connection Flexibility: Threaded and Socket Weld Options
This 3-piece ball valve comes with standard threaded connections for easy installation and optional socket weld ends for high-pressure or permanent installations. Both configurations provide excellent sealing performance and compatibility across different pipeline systems handling liquids or compressed air.
Full Port Flow Design
The full port internal bore ensures unrestricted flow and minimal pressure loss, maintaining high efficiency in your process line. This design also reduces turbulence and wear, ensuring smoother operation and better medium control across a wide range of applications, from pneumatic automation to chemical processing.
Performance and Maintenance
The WP11-3PS is designed for long-term operational reliability under fluctuating air pressure. It offers stable torque output and smooth valve rotation, tested for over one million cycles. Maintenance is simplified by the 3-piece construction, allowing internal parts to be cleaned or replaced without full system shutdown—reducing downtime and extending service life.

Customization Options
WANVALVE provides flexible customization for its pneumatic actuated ball valves. Customers can select actuator types (NAMUR, ISO, or direct mount), signal feedback options, limit switches, or positioners to integrate with control systems. End connections are available in threaded or socket weld, and actuation can be tailored as double acting or spring return to fit various automation needs.
Compliance and Standards
Each WP11-3PS is tested to meet ISO 5211 and API 607 standards for fire-safe and pressure-tight performance. Every unit undergoes hydrostatic and pneumatic testing before shipment, ensuring zero leakage and full compliance with CE and RoHS regulations. These stainless steel ball valves meet the reliability demands of industries such as pharmaceuticals, food processing, and petrochemicals.
