What Are The Classifications Of Sanitary Butterfly Valves?
Sanitary Butterfly Valve is a valve specially designed to meet the high requirements of hygiene and cleanliness in industries. It is widely used in pipeline systems in food, pharmaceutical, cosmetic, beverage and other industries. So do you know what the classification of sanitary butterfly valves is?
The classification of sanitary butterfly valves is as follows:
Classification by sealing form
Soft-sealed sanitary butterfly valve: The seal is made of soft materials such as rubber, has good elasticity and sealing performance, and can adapt to different working conditions and media. The soft-sealed butterfly valve has a good sealing effect, can effectively prevent the leakage of the medium when closed, and the price is relatively low, and it is widely used.
Hard-sealed sanitary butterfly valve: The seal is made of cemented carbide and other materials, with high hardness, resistance and high temperature resistance. Hard-sealed butterfly valves are suitable for harsh working conditions such as high temperature, high pressure, and strong corrosion, but the sealing performance is slightly inferior to that of soft-sealed butterfly valves, and the price is also higher.
Classification by drive mode
Manual sanitary butterfly valve: The opening and closing of the valve is controlled by manually operating the handle or handwheel. It has a simple structure and low cost. It is suitable for occasions where the operation frequency is not high and there are people on duty on site.
Pneumatic sanitary butterfly valve: uses compressed air as a power source to drive the cylinder to drive the valve stem to rotate. Pneumatic butterfly valves are quick to act, quick to respond, and explosion-proof. They are often used in industrial environments where flammable and explosive gases exist, as well as occasions where the valve opening needs to be quickly controlled.
Electric sanitary butterfly valve: The valve stem is driven by an electric actuator to rotate, which can achieve remote control and automatic operation. The electric butterfly valve has high control accuracy and is suitable for occasions with strict requirements on valve opening control, frequent operation or unattended operation.
The sanitary butterfly valve adopts materials and reasonable structural design. The sanitary butterfly valve has high resistance and corrosion resistance. It can operate stably for a long time in harsh working environments, reducing the frequency of equipment maintenance and replacement and reducing the cost of use.
