V-ball in the pipeline is mainly used for cutting, distribution and change the flow direction of media Z641F pneumatic valve vendors, it requires can be closed tightly with a 90-degree rotation operation and a small torque. Most suitable valve make the switch, cut off valve Z641F pneumatic valve manufacturers, but the recent development has been designed to make it a ball and control the flow of the throttle, such as V-ball. Valve Co., Ltd. Shandong Everbright produce such a wide range of application types of valves, reliable, no internal leakage, leakage phenomenon, frequent switching is not stuck, rusty Weifang valve, the vast chemical plants, thermal power plants, steel mills, printing and dyeing plants, food plants are the best choice. 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. _ Everbright valve pneumatic valve price model (certified) _ pneumatic valve provided by Shandong China Everbright Limited valve.
