Control valves

We supply to specification general control valves. A flow control valve regulates the flow or pressure of a fluid. Flow Control valves are controlled elextronically or mechanically. Flow meters or temperature gauges are often used. Control valves usially include actuators and positioners. Pneumatically-actuated globe valves and hydraulic actuators (also known as hydraulic pilots)are typically used with the valve. With an automatic control valves, the hydraulic actuators respond to changes of pressure or flow and will open/close the valve. Hydraulically operated automatic control valves do not need an external power source. The fluid pressure is opens and closes the valve.
