Imported pneumatic flange ball valve (Q641F, Q641H) has the characteristics of fast switching speed, large circulation capacity and good sealing performance. It is composed of a flanged ball valve connected with a pneumatic actuator, which can be divided into switch type and adjustment type according to different functional forms. When the pneumatic flanged ball valve is opened, the diameter of the valve body channel and the connecting pipe forms an opening, and the medium flows without resistance. In addition to oil, gas, liquid and other media, it is also suitable for controlling sewage and media containing fiber impurities. The pneumatic flange ball valve is equipped with a valve positioner, which can input an analog signal of 4-20mA, which can arbitrarily control the opening of the ball valve spool and realize the proportional adjustment of medium flow, temperature, pressure and other parameters.
Advantages of imported pneumatic flanged ball valve (Q641F, Q641H):
1.According to the working conditions, the pneumatic flange ball valve can be divided into two sealing structures: soft seal (-30 180) and hard seal (-40 450), so as to be used reasonably under different media, different temperatures and different pressures.
2.The power source of the pneumatic flanged ball valve is gas, which does not come into contact with sparks. Theoretically, it has explosion-proof function and is relatively safe. And if there is a gas leak, the gas can be discharged directly, which has no pollution to the environment and high safety.
3.From the point of view of valve diameter, due to the reason of torque force, manual ball valves can generally only be configured with ball valves below DN300, while pneumatic flange ball valves can be configured with a wide range of diameters, not only small diameter ball valves, but also large diameter ball valves. Pneumatic ball valves are now available up to DN1200 diameter.
Imported Pneumatic Flange Ball Valve (Q641F, Q641H) Optional Accessories:
