Benefits Of Pneumatic Actuated Wafer Thin Ball Valve:
In order to provide customers with special fluid control solutions, we create and provide this pneumatic wafer thin ball valve to you. The advantages of thin ball valves are compact design, saving installation space, easy installation and easy operation. It can be well used in various pipelines, such as water supply pipelines, oil pipelines and so on.
The advantages of pneumatic actuators are fast response, environmental protection and explosion-proof. Combined with other pneumatic components, it can be easily controlled remotely, helping you improve productivity and project safety.
Features of COVNA Pneumatic Actuated Wafer Ball Valve:
- The unique eccentric design enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve
- The clever wedge-shaped design makes the valve have the function of automatic sealing as the valve is closed and tighter, and the sealing surfaces are compensated with zero leakage
