Q641F-16P/C High Temperature Control Pneumatic Ball Valve Flange Cast Steel with Stainless Steel 304 Quick O-Type Shut-Off

Purpose and functions:

• The Q641 pneumatic flange ball valve only needs to be rotated 90 degrees by air and a small rotational torque to close tightly. The equal valve body cavity of the pneumatic flange ball valve provides a straight flow path with small resistance for the medium. It is generally considered that pneumatic flange ball valve is most suitable for direct opening and closing, but recent development has designed the ball valve to have the function of throttling and controlling flow. The main feature of the pneumatic flange ball valve is that it has a compact structure, is easy to operate and maintain, and is suitable for general working media such as water, solvents, acids, and natural gas. The pneumatic flange ball valve is also suitable for media with harsh working conditions, such as oxygen and peroxide. Hydrogen, methane and ethylene, etc. The body of pneumatic flange ball valve can be integral or combined.

Features:

• The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

• It has simple structure, small size and light weight.

• Tight and reliable, plastic is widely used as the sealing surface material of ball valves at present, with good sealing performance, and has also been widely used in vacuum systems.

• It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for long-distance control.

• Easy to maintain, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is relatively easy to disassemble and replace.

• 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.

• It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure. Pneumatic flange ball valves have been widely used in petroleum, chemical industry, power generation, papermaking,
