1. Vulcanized valve seat: Made of special vulcanized material, it has good wear resistance and sealing performance, ensuring long-term stable operation of the valve.
2. Extended Stem Butterfly Valve this design is used in underground or buried service applications. The extended stem allows the valve to be operated from the surface or by extending the actuator. This makes it ideal for underground pipelines.
3. Flange connection: Standard flange connection is used to facilitate connection with other equipment and has a wide range of applications.
4. Various actuators: electric actuators, but other actuator also can be selected according to user needs to meet different operating needs,such as worm gear, pneumatic, etc.
5. Scope of application: widely used in pipeline flow control in petroleum, chemical industry, metallurgy, water treatment and other fields.
6. Sealing performance: When the valve is closed, it can ensure complete sealing and prevent fluid leakage.
