What is a 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.
Control valve is widely used in heavy equipment such as excavator, tractor and loader. It can control fuel or pressure to make the parts of machine work more precisely.
Different types of valve
Control valve: Controls flow parameters proportional to an input signal received from the central control system. Examples: Globe valve, angle valve, ball valve
Shut-off / On-off valve: These valves are either completely open or closed. Examples: Gate valve, ball valve, globe valve, angle valve, pinch valve, diaphragm valve
Check valve: Allows flow only in a single direction
Steam conditioning valve: Regulates the pressure and temperature of inlet media to required parameters at outlet. Examples: Turbine bypass valve, process steam letdown station
Spring-loaded safety valve: Closed by the force of a spring, which retracts to open when the inlet pressure is equal to the spring force
