V-ball (pneumatic control) is a quarter-turn valve V-shaped structure sellers, by V-type valve, pneumatic actuators, positioners and other annexes; there is an approximately equal percentage flow characteristics inherent ratio; dual bearings Structure V-ball offer, start torque, with excellent sensitivity and speed sensors; superior shear capacity. V-ball (pneumatic control) pneumatic piston actuator using compressed air as a power source to drive the movement of the piston crank through a 90-degree V-type rotary valve manufacturers, to automatically open and close the valve. V-ball leaks common problems and solutions (1) leak was sealed between the V-ball valve seat and causes: A. when you close the actuator does not reach 90 degrees; Solution: Adjust the actuator stroke, it can entirely in the fully closed state. B. sealing surface wear; Solution: Remove the seal seat, remove the ball, seal and valve seat grinding repair. If the seal seat badly damaged, you can replace the seal seat. (2) V-type valve actuator leak causes: AO-ring badly damaged; Solution: Replace with a new O-ring.
