Characteristics

Pneumatic butterfly valves use compressed air as their power source. When compressed air enters the pneumatic actuator, it pushes the piston or gear rack and other components inside the actuator to move, which in turn drives the valve stem and butterfly plate to rotate, achieving the opening or closing of the valve. By installing a valve positioner, the rotation angle of the butterfly plate can also be controlled, thereby accurately adjusting parameters such as flow rate and pressure of the medium in the pipeline.

Key Advantages

Quick Opening and Closing Response

Powered by compressed air, the opening and closing time only takes a few seconds, far faster than manual or electric drives, ideal for emergency shutdowns.

Adaptive Automation Integration

Compatible with solenoid valves, positioners, and limit switches to connect easily to PLC and DCS systems for intelligent production.

Low Operating Cost

Simple structure with a low failure rate. It eliminates complex explosion-proof protection needed for electric drives in hazardous zones.

Packing

📦 Standard export wooden case packaging for maximum protection during transit.

Application Scenarios

The application scope covers municipal engineering, industrial manufacturing, and fluid regulation, especially where space is limited and automation is required.

Frequently Asked Questions

?What is the working principle of this valve?

Pneumatic wafer butterfly valves use compressed air to drive a piston or gear rack, which rotates the valve stem and plate. This allows for rapid opening, closing, or precise flow modulation when paired with a positioner.

?What temperature range can it handle?

The valve is suitable for temperatures between -20°C and 120°C, covering standard industrial applications for water, air, and various chemical media.

?Is it compatible with automated systems?

Yes, it can be integrated with solenoid valves, limit switches, and positioners to connect with PLC or DCS systems for remote monitoring and proportional control.

?How reliable is the sealing?

It features a concentric structure and bidirectional sealing, achieving a zero-leakage grade. The investment casting workmanship ensures long-term reliability in high-pressure environments.

?Is it safe for explosive environments?

Absolutely. Since it is pneumatically driven, there is no risk of electric sparks at the actuator, making it ideal for flammable and explosive chemical or mining sites.

?How is the product protected during shipping?

Every valve is packed in a standard export wooden case to prevent physical damage and ensure it arrives in perfect condition at your facility.
