Q71F-16P Clamped Thin Ball Valve is connected between two pipeline flanges with double-headed bolts, and the handle only needs to be rotated by 90° for quick opening and closing, which is easy to operate. When the ball valve is in the open position, the spool has no resistance, so the pressure drop through the valve is very small, so it has better flow control characteristics. Has a short structural length, small size, light weight, flexible opening and closing, easy to install and so on. Widely used in petroleum, chemical, metallurgy, pharmaceutical, food, power station, light industry and other various fields.
