“FLOW-ON” offers Pneumatic Actuator Operated Investment Casting WCB / CF8 / CF8M Ball Valve in Two Piece / Three Piece design engineered for multiple ON/OFF operations in the down stream. Actuators are effectively used in a ball valve to control the flow of different liquid and gas from a remote location with the use of electrical or pneumatic power. With the help of this feature, we can reduce the need for the operator to open or close the flow of liquid manually and increase safety concerns with productivity. We provide ball valve actuators that are driven by pneumatically or by an electrical motor. However, some standard options given are position indication and safe spring, which can open or close in the event of energy loss. We provide these pneumatic ball valve in a wide variety of size, configurations, and designs to automate any application.
