Control Valve

‘CBRO’ Pneumatic & Electric Actuated Butterfly Valves, control the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle, which permits flow in only one direction. Unlike ball valves, they do not have any pockets in which fluids may become trapped when the valve is closed. They are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe, which when rotated on a shaft, seals against seats in the valve body. They are normally used as throttling valves to control flow.
