Butterfly valve

U-shaped butterfly valve adopts upper-mounted structure, which reduces the connecting bolts of the body itself under high pressure and large caliber conditions, enhances the reliability of the valve and overcomes the influence of system self-weight on the normal operation of the valve.

U-shaped butterfly valves are widely used in diversion and confluence or flow switching devices of medium in coal chemical industry, petrochemical industry, rubber, paper making, pharmaceutical and other pipelines.

Main parameters:

U butterfly valve nominal diameter: DN50mm-DN300mm;

U-type butterfly valve nominal pressure: PN1.0MPa-1.6MPa;

Temperature range of U-type butterfly valve: - 29 C - 300 C.

Butterfly valve, also known as flip valve, is a simple structure control valve, which can be used for switch control of low-pressure pipeline media. Butterfly valve refers to a valve whose closing parts (disc or butterfly plate) are discs and rotate around the valve axis to open and close.

Valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting off and throttling in the pipeline. The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating.

Butterfly valve is a kind of valve which uses disc type hoist to turn back and forth about 90 degrees to open, close or regulate medium flow. Butterfly valves are not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving moment, simple in operation and quick in operation, but also have good flow regulation function and sealing characteristics. They are one of the fastest growing valve varieties in recent decades. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large caliber, high sealing, long life, excellent regulation characteristics and multi-function of a valve. Its reliability and other performance indicators have reached a high level.
