Pneumatic Plastic PVC Butterfly Valves With Fluorine Lined
The standard ISO square size allows for the direct mounting of actuators, ensuring compatibility and ease of installation. The disc and seat feature a trapezoidal elastic lining, which ensures a hermetic seal, enhancing the valve’s performance and reliability.
Furthermore, the bushing serves to completely isolate the valve body from the process flow, preventing any contamination or interference. Acting as flange gaskets on both sides of the valve, the bushings contribute to the overall sealing integrity of the system.
To prevent liner slippage and compression, the body cavity is equipped with special channels, ensuring the stability and longevity of the valve’s components. Additionally, EPDM, NBR, and PTFE seal O-rings are employed to provide effective shaft sealing, further enhancing the valve’s sealing capabilities across various operating conditions.
