Design features >>>
1. Zero leakage: The manufacturing process ensures two-way zero leakage performance for the butterfly valve;
2. Tongue and groove valve seat: Ensures that the valve body does not come into contact with the medium, eliminating the need for a flange gasket during installation;
3. Two-way sealing of valve plate: Reduces friction and extends the service life;
4. Customizable services: Includes options like vacuum design, powder transportation, and expansion valve seat designs.

Design features of centerline butterfly valve >>>
1. Installation platform: The connection with the actuator conforms to the ISO5211 standard. (See Figure ① above)
2. Pressing plate: Designed to prevent the valve stem from coming out and increase the service life. (See Figure ② above)
3. Stem sheath: Corrosion-resistant and capable of absorbing lateral thrust under heavy loads. (See Figure ③ above)
4. Valve stem: The male and female key teeth are designed to fit together tightly with interference, ensuring a secure connection with the valve plate to increase service life. (See Figure ④ above)
5. Valve seat: A variety of sealing materials can be selected according to different working conditions. (See Figure ⑤ above)
