Pneumatic ball valve features

The structure of the pneumatic ball valve compared with other ball valve ( Such as: stainless steel ball valve,
forged steel ball valve, sulfur discharge ball valve, ball valve, three-way ball valve, pneumatic ball valve, etc. ) Is simple, it is only by a few parts with pneumatic actuators with respect to OK, information consumption province; Small volume, light weight, small installation feet inches, small drive moment,
pressure regulating valve, easy to operate, agile, quick opening and closing in a rotate 90 °.


pneumatic ball valve has a good flow regulating effect and closed sealing characteristics, application in large and medium diameter, low and medium pressure fan domain, pneumatic ball valve is the dominant valve situation; Ball valve is in full open position when the butterfly plate thickness is medium flow
only after the body resistance, so by what happens to the valve pressure drop is small, so it has good flow control characteristics; Valve seal and metal sealing machine has two sealing type. Elastic sealing valve, sealing ring can be set
embedded in the body or attached to the butterfly plate around; Take the metal sealing valve generally live longer than elastic sealing valve; If the request is used as flow control, pneumatic ball valve is important to accurately select the valve size and type of the
. The structure of the pneumatic ball valve principle, especially suitable manufacturing large diameter valves. It not only in oil and gas, chemical industry, water disposal industry widely applied, but also used in cooling water system of thermal power plants.


the commonly used pneumatic ball valve has a wafer pneumatic ball valve and the flange type pneumatic ball valve two kinds. The wafer pneumatic ball valve is the valve with stud
door connection in place between two pipe flanges, the flange type pneumatic ball valve is a valve with flange, bolts on the valve flange connection on both ends on the pipe flange.
