V-ball leaks common problems and solutions 1.V A. ball valve packing leak may be because of the V-ball packing bolt is not pressed; run lead in the use of V-ball filling out the wear on BV ball valve. Solution: Remove the back cover of V-ball packing V-ball price, replace V-ball packing. Under normal circumstances rather tight V-ball packing gland nut can be resolved at the V-ball packing leaks V-pneumatic valve characteristics and uses a pneumatic piston actuator using compressed air as a power source V-ball supplier, by movement of the piston driven by a 90-degree rotation crank V-ball valve manufacturers, to automatically open and close the valve. It's part of: adjusting screw actuator box, crank, cylinder block, cylinder shaft, piston, connecting rod, cardan shaft. 2, pneumatic control valve works: pneumatic valve actuators and regulation by agencies. Implementing agencies regulating valve thrust component, which according to the size of the control signal to produce a corresponding pressure thrust, push adjusting mechanism action. Pneumatic control valve is a valve regulating member, it is in direct contact with the regulating medium, adjusting the flow rate of the fluid.
