Highlight: Three-piece flanged ball valve
Product introduction:
Three-piece ball valve is a relatively new type of ball valve, which can be tightly closed with only 90 degrees of rotation and a small turning torque. The completely equal valve body cavity provides a small resistance and straight flow path for the medium, which gives it advantages that ordinary ball valves do not have. For example, the switch has no friction, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the equipped actuator, and equipped with a multi turn electric actuator, it can achieve the adjustment of the medium and tight cutting, which can be widely used in strict cutting off conditions such as petroleum, chemical, urban water supply and drainage.

Product features:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close, with only a 90 ° rotation from full open to full close, facilitating remote control.
5. Easy to maintain, the ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement more convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
