Pneumatic wafer butterfly valves are a type of valve featuring a disc-shaped valve plate that controls fluid flow through a pipe. The valve plate is mounted in the pipe's diameter direction and is connected to the valve stem, which moves to open and close the valve. The disc rotates within the cylindrical channel of the valve body around an axis, with its rotation angle ranging from 0° to 90°. When the disc rotates to 90°, the valve is fully open, allowing unrestricted flow.
These valves are known for their simple structure, compact size, lightweight design, and low material consumption, making them an efficient choice for various applications. The small installation size and quick opening and closing action make pneumatic wafer butterfly valves highly effective for on/off control, regulation, and fluid shutoff in pipelines. The valve's 90° rotary motion is highly responsive and provides low driving torque, which contributes to its energy-efficient operation.
Pneumatic wafer butterfly valves are particularly suitable for applications requiring good flow control and sealing performance. The disc design enables effective fluid regulation, providing tight closure and preventing leakage. Additionally, these valves are ideal for handling media such as mud and slurries, as they minimize liquid accumulation within the valve and maintain effective sealing even under low pressure conditions. Their low-pressure sealing capability and excellent performance in media adjustment make them a versatile solution in various industries, including water treatment, chemical processing, HVAC systems, and more.
The design also ensures that the valve can be easily maintained and operated with minimal effort, contributing to both cost-effectiveness and long-term durability.
