Sanitary three-piece butterfly valve

The sanitary three-piece butterfly valve is simple in structure, small in size, light in weight, small in size, small in size, easy in operation and quick in operation, and has good flow regulating function and closed sealing characteristics. Three-piece butterfly valve is dedicated to dairy products, food, pharmaceutical, beer, cosmetics and other industrial fields.

First, the working principle of sanitary three-piece butterfly valve
Sanitary three-piece butterfly valve is a circular butterfly plate for the opening and closing parts and with the stem to open, close and adjust the fluid channel of a stainless steel valve. The sanitary three-piece butterfly plate is installed in the diametrical direction of the pipe.

Second, the use of sanitary three-piece butterfly valve
Sanitary three-piece butterfly valve is not only simple structure, small size, light weight, the material consumption of the province, the installation of small size, and the driving torque is small, easy to operate, and can also have a good flow adjustment function and close the sealing characteristics. When fully opened, with a small flow resistance, when opened at about ° to 70 °, but also for sensitive flow control, and thus in the field of large diameter adjustment, the movement of the valve plate with a wipe, and thus Can be used for suspension with fixed particles of the media, according to the strength of the seal can also be used for powder and granular media. 

Third, the sealing performance of sanitary three-piece butterfly valve:
Sanitary tri clamp butterfly valve is a neutral stainless steel soft butterfly valve with the sealing principle, the valve plate can ensure that the sealing surface has a suitable surface roughness value, synthetic rubber seat formed a good surface roughness value in the molding process.

Fourth, the features of sanitary three-piece butterfly valve
1, rubber seals and valve plates are imported, to ensure the use of stainless steel butterfly valve performance and use
2, the use of high-precision CNC lathe fine valve body to ensure a reliable stainless steel butterfly interchangeability, eliminating the need to replace the rubber and can not guarantee the use of its troubles.
3, stem set in the nylon sleeve, reducing the friction and thus open flexible and easy. Steel are made of stainless steel, rubber products.
4, opening and closing range of 90 degrees, can be fixed at every 15 degrees position, with adjustable, and open and close quickly, easy to operate.
5, the valve body are removable connection, simple structure, easy maintenance.
6, modeling light and beautiful, the surface of light and no sticky dust, no burr stalker.
7, the sampling carried out not less than 30,000 times the fatigue life test, to ensure its service life.

Fifth, the health level three-piece butterfly valve selection principle
Sanitary three-piece butterfly valve can meet the requirements to achieve a complete seal, gas test leakage is zero, high life requirements, the working temperature is 10 ℃ to 150 ℃，sanitary butterfly valve is widely used in fresh water, sewage, sea water, Natural gas, food, pharmaceuticals, oils and various acid-base and other thin-walled pipelines.
