Product Description

Sanitary Double Live Connection Butterfly Valve

Sanitary double live butterfly valve is a midline stainless steel soft seal butterfly valve, its sealing principle is that when the valve plate is processed to ensure that its sealing surface has a suitable surface roughness value; sanitary grade double live butterfly valve inside and outside with a high-end polishing equipment processing to reach the surface Precision requirements; sanitary double butterfly valve is suitable for liquids, gases, oils, all kinds of highly corrosive chemical media.


First, the health of double live butterfly valve working principle

The hygienic double live butterfly valve is a Stainless Steel Valve that uses a round butterfly plate as the opening and closing part and opens, closes and regulates the fluid passage with the rotation of the valve stem. The hygienic double butterfly valve is installed in the diameter direction of the pipe. In the Stainless Steel Butterfly Valve body cylindrical passage, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0° and 90°, and when the valve rotates to 90°, the valve is fully open.

Second, sanitary double butterfly valve use

Sanitary double live butterfly valve is dedicated to dairy products, food, pharmaceuticals, beer, cosmetics and other industrial fields. All parts in contact with the media are mirror-polished.

There are two types of sanitary double-live butterfly valve seals Ф25-Ф108: EPDM, silicone (SI), Ф57 and below are EPDM; the opening and closing parts reciprocate around 90°. A stainless steel butterfly valve that opens, closes, and regulates fluid passages.

Sanitary double-acting butterfly valve not only has simple structure, small size, light weight, material consumption, small installation size, but also small driving torque, easy and quick operation, and can also have good flow regulation and close sealing properties at the same time. When it is fully opened, it has a small flow resistance, and it can perform sensitive flow control when it is opened between about ° and 70. Therefore, in the field of large-diameter adjustment, the movement of the valve plate is wiping off. It can be used for media with suspended solids and can also be used for powdered and granular media depending on the strength of the seal.

Third, sanitary double live butterfly valve sealing performance:

Sanitary double live butterfly valve is a midline stainless steel soft seal butterfly valve, the sealing principle is that when the valve plate is processed to ensure that the sealing surface has a suitable surface roughness value, the synthetic rubber valve seat in the molding forming the sealing surface suitable surface roughness value. When the stainless steel butterfly valve is closed, through the rotation of the valve plate, the outer circular sealing surface of the valve plate presses the synthetic rubber valve seat, so that the synthetic rubber valve seat generates elastic deformation and the elastic force acts as a sealing ratio to ensure the sealing of the valve.
Four, sanitary double butterfly valve features

1. Imported parts are used for rubber seal ring and valve plate to ensure the performance and use of stainless steel butterfly valve.

2, the use of high-precision CNC lathe fine car body, to ensure the reliable exchange of stainless steel butterfly valve, eliminating the need to replace the rubber and can not guarantee the performance of the trouble.

3. The valve stem is equipped with a nylon bushing, which reduces the friction force and thus opens up flexibility. The steel parts are made of stainless steel. The rubber is made of food rubber and has high sanitary quality.

4. The valve body diameter and pipe diameter are equal, the narrow and streamlined valve plate opens in the same direction as the fluid, the flow rate is large and the resistance is small. No material accumulation handle adopts a pulling type and a pulling type and can withstand a large operating torque. It is not easy to pull off.

5, opening and closing range of 90 degrees, can be fixed at every 15 degrees, with adjustable, and opening and closing quickly, easy to operate.

6, the valve body is detachable connection, the structure is simple, easy maintenance.

7, the shape of light and beautiful, bright surface without sticky dust, no burr bar.

8, through strict strength and sealing test to ensure quality.

9. Sampling tests for fatigue life of not less than 30,000 times ensure the service life.
Fifth, the principle of selection of sanitary three-piece butterfly valve

Sanitary double live butterfly valve (middle line soft seal butterfly valve) is applicable to fresh water, sewage, seawater, salt water, steam, which require complete sealing, zero gas test leakage, high life expectancy, working temperature in this 10°C to 150°C, Natural gas, food, medicines, oils, and various acids and alkalis and other thin-walled pipelines.
