Extended Stem Flange Butterfly Valve

The filter pressure reducing valve can accurately filter the moisture and oil in the air source, ensuring the cleanliness of the air source entering the pneumatic actuator. The limit switch can timely feedback the opening and closing status of the valve, avoiding errors caused by improper operation. The pneumatic actuator adopts a double acting design, which can quickly respond and cut off in case of emergency.

Extended rod pneumatic flange butterfly valves can usually be used in underground deep wells. Workers do not need to go underground, and the valve can be opened and closed on the ground. In humid and easily polluted environments, filter pressure reducing valves can ensure the stable operation of pneumatic actuators. The staff can monitor the status of the valve in real time based on the limit switch to prevent abnormal situations.

Ordinary pneumatic butterfly valves do not have extension rods, making underground work very difficult and greatly increasing costs. However, this flange butterfly valve with extension rods solves this problem. In terms of gas source processing, it has a filter pressure reducing valve that is more adaptable than ordinary pneumatic butterfly valves, and the limit switch is also more suitable for intelligent scene management.
