pneumatic V-ball valve Description
A pneumatic V-ball valve is an industrial valve that controls media flow by rotating a V-notch ball driven by a pneumatic actuator. This valve features a right-angle rotary structure and is available in floating, fixed, and resilient types. The valve core and seat are sealed with metal or metal-to-PTFE seals. It supports double-acting/single-acting pneumatic modes, and a positioner can be used for proportional adjustment. Its V-notch design provides precise flow control and shearing capabilities, making it suitable for controlling media containing fibers, solid particles, and high viscosity.
The valve body is made of cast steel or stainless steel, with a nominal diameter of DN25-DN500. It is suitable for temperatures from -20℃ to 450℃. The actuator conforms to standards such as GB12237 and API608, and can be compatible with solenoid valves, limit switches, and other accessories. It supports Ex dIIBT4 explosion-proof rating. It is mainly used in industrial automation systems in petroleum, chemical, pharmaceutical, and power industries for pipeline pressure regulation, reactor feed control, and suspension treatment.

Features and Advantages of Pneumatic V-ball Valves
- Low Fluid Resistance: The fluid resistance coefficient of a pneumatic V-ball valve is equal to that of a pipe section of the same length, resulting in very low resistance when fluid flows through.
- Simple Structure: Pneumatic V-ball valves have a relatively simple structure, are small in size and lightweight, and are easy to operate and maintain.
- Reliable Sealing: The sealing surface materials of pneumatic V-ball valves widely use plastics and other materials with good sealing properties, which are also widely used in vacuum systems, ensuring reliable sealing.
- Easy Operation: Pneumatic V-ball valves open and close quickly, requiring only a 90° rotation from fully open to fully closed, facilitating remote control.
- Easy Maintenance: The simple structure of pneumatic V-ball valves and the generally movable sealing rings make disassembly and replacement convenient.
- Wide Application Range: Pneumatic V-ball valves have a wide range of diameters, from a few millimeters to several meters, and can be used in high vacuum and high pressure applications.
Pneumatic V-Port Ball Valve Ordering Instructions
Essential Information for Ordering:
① Product Name and Model: Please specify the product name and model of the pneumatic V-port ball valve.
② Valve Size (Bore Diameter): Please indicate the required valve size (e.g., DN25, DN50, etc.).
③ Accessories: Please confirm whether any accessories are required (e.g., solenoid valve, positioner, limit switch, air filter regulator).
Standard Ordering Process:
If the valve model has already been selected by your design institute (e.g., "Zhenggang Valves" model), please place your order directly with our sales department using the specified model number.
Complex or Critical Applications:
For applications with high importance or complex environmental conditions (e.g., extreme temperatures, pressures, corrosive media), we strongly recommend providing detailed design drawings and specifications. Our GNEE Group technical experts will review them to ensure optimal valve selection and application suitability.
