How to choose the right sanitary butterfly valve?
Working pressure of sanitary butterfly valve is lower than the standard atmospheric valve in the vacuum pressure. Now common health-class food-grade butterfly valves are refers to the case of sanitary under normal pressure butterfly valve, the nominal pressure is PN <1.6MPa.
Sanitary butterfly valve was installed in the pipe diameter direction. In the butterfly valve body cylindrical channel, the disc-shaped butterfly plate rotated around the axis, sanitary pneumatic butterfly valve rotation angle is 0 ° to 90 °, the valve is fully open card status, rotation angle is 0 ° -90 °, the valve is in a fully open state. Sanitary pneumatic valve is featured by simple structure, small size, light weight, simple operation, while the valve has good fluid control characteristics. Butterfly valve is in a fully open position, the disc thickness is the only flow through the valve body in different occasions, sanitary pneumatic butterfly valve models are different, choose to do the appropriate adjustments.
Installation requirements of sanitary butterfly valve in the drying equipment storage tank
Stainless steel large-diameter sanitary valve has good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics; bending, pressing and other hot workability, no heat treatment hardening phenomenon. In a variety of health-valve products are more popular. Common sanitary butterfly valves: sanitary food grade butterfly valve, large diameter sanitary thread butterfly valve, sanitary clip on the butterfly valve, large diameter sanitary flange butterfly valve, sanitary quick-mounted butterfly valve.
Large diameter sanitary butterfly valve has the valve body and disc plates are used to process high-precision CNC lathes. Sanitary butterfly valve is featured by small size, simple composition, light weight.
The use is relatively simple, able to quickly open and close. Valve has a very good fluid control characteristics, sanitary pneumatic butterfly valve in a complete open position, the disc thickness is the only medium through the valve body resistance, the pressure generated by the valve is small, with good flow control characteristics. Sanitary butterfly valve has a ballistic seal and metal seal two seal types. The sealing ring is on the disc side of the valve body.
1. With high-precision CNC lathe body to ensure the reliability of the butterfly valve interchangeable, eliminating the better performance can not guarantee the rubber trouble;
2. Large-diameter sanitary butterfly valve rubber seals and valve plate with imported parts to ensure the use of hard surface sealing butterfly valve performance and service life;
3. Steel pieces made of stainless steel, rubber, rubber used in food, health, high quality;
4. When the narrow and streamlined valve plate and the fluid is in the same direction, the flow is large with small resistance, no material accumulation;
5. The valve body can be removed by using the connection, simple structure, maintenance is also more aspects.
