Compensated flow control valves
Needle valves are used to equalize the oil flow to the engine. They are generally used to control the flow rate of liquids and gases as they can regulate the oil in one or both directions. A relief valve is mandatory in the system to discharge the oil in excess. The valves dissipate energy and increase the temperature of the fluid. They are sutable for use in low frequency applications or with reduced excess of oil.
