Butterfly Valve for Water is a rotary valve that uses a disc-type opening and closing member to rotate 90° or 90° to open and close the channel. The movement of the Butterfly Valve for Water disc is wiping, so most butterfly valves can be used for media with suspended solid particles. Commonly used Butterfly Valve for Water has two types: wafer type butterfly valve and flange type butterfly valve. The wafer type Butterfly Valve for Water uses stud bolts to connect the valve between the two pipe flanges. The flange type Butterfly Valve for Water has a flange on the valve, and the two ends of the valve are flanged to the pipe with bolts. On the flange.

1) The Butterfly Valve for Water has small dimensions, short length, simple structure and light weight.
2) Butterfly Valve for Water is easy to operate, open and close quickly, only need to rotate the valve flap 90°
3) The Butterfly Valve for Water has good sealing and adjustment performance. Since rubber is used as the sealing ring, the compression and resilience are good, so the sealing performance is good. The valve flap is open between 15° and 70°, which can carry out sensitive flow control.
4) The operating torque and fluid resistance of the Butterfly Valve for Water are small. According to measurement, the fluid resistance of butterfly valves is less than that of other types of valves except ball valves.
5) Due to the limitation of the sealing material of the Butterfly Valve for Water, the operating pressure and operating temperature range of the butterfly valve is relatively small.
1) Butterfly Valve for Water is suitable for water engineering, water supply and drainage pipelines, petrochemical, smelting, food and other system pipelines.
2) Butterfly Valve for Water can be used as a regulating and intercepting device on a variety of corrosive and non-corrosive liquid, gas, semi-fluid and solid powder pipelines and containers.
3) The Butterfly Valve for Water for fire protection is widely used in high-rise building fire protection systems and other pipeline systems that need to display valve switching status.
