1. Dual half-shaft design: The valve opening and closing process is more stable, reducing fluid resistance and improving flow control accuracy.
2. Vulcanized valve seat: Made of special vulcanized material, it has good wear resistance and sealing performance, ensuring long-term stable operation of the valve.
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.
7. Easy maintenance: Simple structure, easy to maintain and repair, reducing operating costs.
