Soft Seal Electric Wafer Butterfly Valve
Basic Info
- Electric wafer butterfly valve can be controlled remotely. With electric actuators, butterfly valves can be controlled using electronic signals.
- Electric wafer butterfly valves are available in switch type and regulating type. That is to say, the butterfly valve can be controlled by opening and closing only, or by adjusting the flow rate.
- Wafer butterfly valve: Among all valves, the structure length is the shortest, the space is the smallest, and the cost is meager.
- Soft backseat: high elasticity and strong sealing. And can be replaced to achieve cost savings.
