The Pneumatic Butterfly Valve is a high-performance, wafer-type valve designed to offer reliable operation in a variety of industrial applications. Compliance with design standards IS 13095 / BS EN 593 (BS 5155) ensures that this valve meets rigorous quality and safety requirements. Constructed from durable S.G. iron, it features a high-grade stainless steel disc (CF8 / CF8M) that is precisely guided between two stems for efficient operation. The double-acting pneumatic actuator is built with advanced scotch yoke technology, enabling higher torque at both end positions while eliminating the complexities associated with rack and pinion systems. With an integrated position indicator and adjustable center stopper, this valve guarantees accurate positioning for both open and closed states. Additionally, it is equipped with integrally molded rubber lining options, including EPDM, Nitrile, Neoprene, Viton, and Silicon, providing effective sealing to the valve disc and ensuring a long-lasting service life. This product is capable of handling various testing pressures and is ideally suited for applications needing compatibility with numerous flange standards.
