A. AT Pneumatic V-type Adjusting Flange Ball Valve Introduction
       AT Pneumatic V-type Adjusting Flange Ball Valve Pneumatic Actuator adopts the new AT/GT series pneumatic actuator. Its structure has obtained the national utility model patent, with double action and single acting type (spring reset ), the use of rack and pinion structure transmission, the performance is more safe and reliable; large-diameter valves using AW series of pneumatic actuators, fork-type transmission structure, reasonable structure, large output torque.
      AT Pneumatic V-type adjusting flange ball valve is divided into soft seal and hard seal according to the sealing performance; it is divided into regulation type and cut-off type according to the adjustment mode, and the cut-off type is divided into single action and double action type according to the action mode, and the adjustment type is double action type. The unique advantage of the single-acting type is that once the power source fails, the ball valve will automatically be in the closed or open position as required by the control system.

Two, AT pneumatic V-regulating flange ball valve working principle
       AT pneumatic V-ball valve has a special shape of the fixed V-notch ball and adjustable metal seat structure, when the valve is closed, the V-shaped incision and the valve seat to form a wedge cut Function, can prevent the jam between the ball and the valve seat caused by the phenomenon of dirt, with self-clearing function, especially suitable for media containing fiber slurry, sewage and sticky particles, with a valve positioner can achieve continuous adjustment, and With a small flow resistance, a wide range of adjustment, is a wide range of high-quality control valve.
