Butterfly Control Valve
Butterfly Control Valve Solutions
Chemoil Advance Technology supplies Butterfly Control Valves from recognized manufacturers for flow regulation and automated process control in industrial and process piping systems. Butterfly control valves combine the compact quarter-turn design of a butterfly valve with suitable actuation and control systems to regulate process flow according to operating requirements.
The valve uses a rotating disc to vary the available flow area. By adjusting the disc position, the valve can regulate the flow of compatible liquids, gases and other process media. Depending on the application, the valve can be equipped with pneumatic or electric actuation, positioners, solenoid valves, limit switches and other control accessories.
