First, AT Pneumatic V-Type Adjustment Flange Ball Valve Introduction
 AT pneumatic V-type adjustment flange ball valve pneumatic actuator with a new AT / GT series of pneumatic actuators, the structure of the national utility model patents, double and single acting (spring reset ), The use of rack and pinion structure transmission, more secure and reliable performance; large diameter valve with AW series of pneumatic actuators, fork fork structure structure, reasonable structure, the output torque. 
 AT pneumatic V-type flange ball valve according to the sealing performance is divided into soft seal and hard seal; according to the adjustment method is divided into adjustable and cut off type, cut off by the role of single-acting and double-acting, adjustable type for the double acting. The unique advantage of single acting 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. 
 
 Second, AT Pneumatic V-Type Adjustment Flange Ball Valve Works
 AT aerodynamic V-type ball valve with a special shape of the fixed V-shaped incision ball and adjustable metal seat structure, when the valve is closed, V-shaped incision and the valve seat to form wedge shear Function, can prevent the ball and the seat between the dirt generated by the phenomenon of stuck, with self-cleaning function, especially for fiber-containing pulp, sewage and sticky particles of the media, coupled with the valve positioner can be continuously adjusted, and With a small flow resistance, wide adjustment range, is a wide range of high-quality control valve.
