2、 Detailed information
Product Overview
Eccentric hemispherical control valve ball valve belongs to trunnion ball valve and is also a single seat sealed ball valve. It has the characteristics of fast opening and closing, lightweight, low fluid resistance, simple structure, small relative volume, light weight, easy maintenance, good sealing performance, arbitrary medium flow direction, no vibration, and low noise. This valve is widely used in fields such as chemical engineering, papermaking, petroleum, and power.
Design and inspection can follow standards such as GB/T 12237, GB/T 12221, and GB/T 13927.
main features
① The fluid resistance is small, and its resistance coefficient is equal to that of pipe segments 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 Convenient operation, quick opening and closing, with only 90 ° rotation from full opening to full closing, facilitating remote control.
⑤ Convenient maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement more convenient.
⑥ When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
⑦ Wear compensation can be achieved by increasing the closing angle to compensate for seat wear
