Detail Information
Lever Opreated Wafer Butterfly Valve D71X/J
Wafer butterfly valve is wafer butterfly valve developed with the technology introduced from foreign country, with the advantage of simple structure, good seal performance, easy to open, long service life, easy to maintain. Wafer butterfly valve is widely used in various pipelines for drainage. Wafer butterfly valve can correctly show the open/close status of valve, so ductile iron butterfly valve is widely used in fire control system.
Advantages:
1. Wafer butterfly valve is small operating torque, worm gear actuator.
2. Wafer butterfly valve is easy to operate.
3. Wafer butterfly valve suitable to install handle, worm gear drive, pneumatic, hydraulic, electric and other control devices.
4. Wafer butterfly valve can be installed in any location, easy maintenance.
5. Wafer butterfly valve is sealing performance is reliable and zero leakage.
