Features of sanitary butterfly valve:

1. Sanitary pneumatic butterfly valve is simple, small volume, light weight, small flow resistance, large flow coefficient and good sealing performance. The adjustment range is large. It is the executive unit of instrument in automatic control system.

2. Sanitary butterfly valve adopts electric valve positioner, which is powered by electric signal and compressed air, receives 4-20madc current signal input from control system. The regulator converts compressed air into air source pressure signal input and output, changes the rotation angle of valve plate (0-90 ° arbitrary angle), and has better parameters such as flow regulation and control.

3. The actuator adopts piston type cylinder and crank arm conversion structure, with large output torque, small volume, fully sealed waterproof design and high protection level. The cylinder block adopts mirror cylinder, no oil lubrication, small friction coefficient, corrosion resistance, strong durability and reliability. All drive bearings adopt boundary self-lubricating bearing without oil lubrication to ensure that the transmission shaft is not damaged.

Advantages of sanitary butterfly valve:

1. The rubber seal ring and valve plate of butterfly valve are imported parts, which ensure the service performance and service life of butterfly valve.

2. High precision CNC lathe is used to finish turning the valve body, which ensures the reliable interchangeability of butterfly valve and avoids the trouble of not ensuring its performance due to rubber replacement.

3. The valve stem is inlaid with nylon shaft sleeve, which reduces the friction force, so it can be opened flexibly and easily.

4. The steel parts are made of stainless steel, and the rubber is made of food rubber, which has high sanitary quality.

5. The diameter of the valve body is equal to that of the pipe. When opened, the narrow and streamlined valve plate is consistent with the flow direction, with large flow rate and small resistance, and no material accumulation.

6. The handle is of pull and pull type, which can bear large operating torque and is not easy to break.

7. The opening and closing range is 0 ~ 90 degrees, which can be fixed at the position of every 15 degrees. It is adjustable, quick to open and close, and easy to operate.

8. Sanitary butterfly valve adopts detachable connection, simple structure and convenient maintenance.

9. The shape is light and beautiful, the surface is bright without dust and burr.

10. Through strict strength and sealing test, the quality is guaranteed.

11. At least 30000 times of fatigue life tests were carried out to ensure its service life.
