The pneumatic butterfly valve consists of a pneumatic actuator and a butterfly valve. It uses compressed air as the power source and controls the fluid flow by rotating the butterfly plate to cut off and regulate the fluid.

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)
