Quick-install butterfly valve (duckbill handle) not only has simple structure, small size, light weight, low material consumption, small installation size, and small driving torque, easy and fast operation, but also has good flow adjustment function and closing seal. characteristic. The sanitary manual quick-load butterfly valve has a small flow resistance when it is fully opened, and can perform sensitive flow control when it is opened between about 15° and 70°. Therefore, in the field of large-diameter adjustment, the application of butterfly valves Very common; the movement of the valve plate of the sanitary manual quick-release butterfly valve is wiping, so the welded butterfly valve can be used for media with suspended fixed particles, and can also be used for powdery and granular media depending on the strength of the seal.

The advantages of sanitary manual butterfly valve:

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

2. The valve body is precisely turned by CNC lathe, which ensures the reliable interchangeability of the butterfly valve and avoids the trouble of not guaranteeing its performance due to the replacement of rubber.

3. The valve stem is inlaid with nylon bushing, which reduces the friction force and makes it flexible and easy to open.

4. The steel parts are all made of stainless steel, and the rubber is made of food rubber, with high hygienic quality.

5. The diameter of the valve body is equal to the inner diameter of the pipeline. When opening, the narrow and streamlined valve plate is consistent with the direction of the fluid. The flow rate is large, the resistance is small, and there is no material accumulation.

6. The handle adopts the pulling type and the pulling type, which can bear a large operating torque and is not easy to break.

7. The opening and closing range is 0~90 degrees, which can be fixed at every 15 degrees, with adjustability, quick opening and closing, and convenient operation.

Features

1. The design is novel, reasonable, structure, light weight, quick opening and closing.

2. Small operating torque, convenient operation, labor-saving and smart.

3. It can be installed in any position and easy to maintain.

4. The sealing material has the characteristics of anti-aging, long service life and so on.
