Control valve

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. In automatic control terminology a control valve is . The control valve manipulates a flowing flui such as gas, steam, water, or chemical compounds to compensate for the load disturbance and keep the regulated process variable as close as possible . Each of these control loops is designed to keep some important process variable such as pressure, flow, level, temperature, etc.

Control Valves Pressure Relief Valves.

Bürkert control valves make up a uniquely integrated system of valve , actuator, positioner or process controller ‒ working perfectly in concert for ideal control. Fit and forget – that is what the extensive Bürkert valve program stands for, with its pneumatic and electromotive actuators as well as advanced control technology. Process Valve Automation. GEMÜ offers control valves , control systems and individual automation components for controlling liquids, steam and gases.

Products with highly reliable control valves and cutting-edge smart valve positioners as their key components to continuously meet needs arising from diverse and wide-ranging business sectors. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is achieved as very small . They can be fitted with.
