Product Description:

The expansion butterfly valve produced by Xingneng has a unique design. It uses gas pressure to inflate the special rubber valve seat, and the valve seat extends toward the valve disc, so as to provide uniform pressure for sealing at any time. During the opening and closing of the valve, the valve disc and the valve seat will only contact momentarily, so that the valve disc will only be slightly impacted. However, the hard friction generated by the disc of ordinary butterfly valve rubbing against the valve seat will reduce the performance and service life of the valve.

Xnpzd expansion butterfly valve requires only a small torque when opening and closing, which can make the actuator and valve more durable.

According to the actual comparison test and field application, the performance of xnpzd expansion butterfly valve is superior to other valves. The service life of the butterfly valve can reach 1 to 1 million times, even in the case of severe wear. For dry solids, gases and mud bodies, it is more suitable to use expansion butterfly valves.

Xnpzd expansion butterfly valve series is designed for harsh conditions. A complete range of actuators, limit switches and control devices can effectively meet different application requirements.
