Features
The concentric design of Lever-Operated Flange Concentric Butterfly Valve makes the butterfly plate and the valve body concentric, reducing fluid resistance and increasing flow rate. Replaceable seals are adopted, featuring replaceable rubber seals for convenient maintenance. The unique sealing design and low-friction bearings ensure easy operation. A variety of sealing materials can be selected, suitable for different media and temperature ranges. The ISO 5211 installation interface is adopted to facilitate the installation of various actuators, including manual, electric and pneumatic actuators. Manual lever operation can complete the switch operation in a short time.
