A control valve opens, closes or modulates flow automatically through an actuator or pilot mechanism, holding flow, pressure or temperature at the desired value. Unlike manual valves, it acts on a control signal or on a physical value in the line. From heating and cooling systems and steam heat exchangers to water networks and process automation, control valves are key to energy efficiency and safe operation.
Five main groups by duty: on-off control valves (pneumatic or electric, fully open/closed); modulating control valves (positioned by 4–20 mA / 0–10 V signals); pressure control valves (pressure reducing valves and regulators); thermostatic control valves (self-acting, temperature sensing) and hydraulic control valves (pilot-operated by line pressure).

On-off, modulating, pressure control (pressure reducing), thermostatic and hydraulic control valves.
An on-off valve is either fully open or closed; a modulating valve holds intermediate positions according to the control signal for precise flow control.
The Kv value is calculated from required flow and pressure drop; the valve size is chosen from it and is often smaller than the pipe.
Yes – thermostatic valves use a temperature sensor and hydraulic control valves use line pressure.
