Haiqiao Yap Valve Manufacturing Co., Ltd. [Q644F / Q645F pneumatic ball valve (L-type / T type)] of the manufacturer, with large spot to ex-factory sales! Companies adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect after-sales service, welcome to buy! A pneumatic ball valve Product Overview Q644F / Q645F pneumatic ball valve is a transition back to a three-channel valve for media streaming, confluence and flow switch, any one pipe can be used as an inlet or outlet. Pneumatic three-way ball valve with pneumatic sub-L-valve and pneumatic three T-ball are two, to meet different business process requirements. Pneumatic three L-shaped ball is three pipeline two pipe cutting, pneumatic three T-ball to achieve the three communication pipes confluence with the shunt. Pneumatic ball valve with electric valve positioner package, enter 4 ~ 20mADC signal and 0.4 ~ 0.7MPa air source to control operation to achieve the pressure, flow, temperature, level and other parameters to adjust. Also with travel limit switches, solenoid valves, valves and 0.4-0.7MPa gas source switching operation can be achieved, and sent two pairs of passive contact signal indicating the valve switch. Q644F / Q645F pneumatic ball valve is widely used in chemical, petroleum, textile, electricity, food and pharmaceutical, refrigeration, aviation, aerospace, paper and other industries. Second, pneumatic ball valve Features (1) the fluid resistance is small, its drag coefficient equal to the same length of pipe. Simple (2) structure, small size, light weight. (3) close and reliable valve sealing surface material widely used plastics, sealing, and has also been widely used in the vacuum system. (4) easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. (5) easy maintenance, simple ball valve, seals are generally activities, removal of the replacement is more convenient. (6) In the fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion pneumatic ball valve sealing surface. (7) for a wide range from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied.
