What Are Hydraulic Servo and Proportional Valves?

A hydraulic servo valve is a valve which controls how and when hydraulic fluid is delivered to a hydraulic actuator. Typically, servo valves are controlled electronically and are known as EHSVs, or electrohydraulic servo valves. They've been used since World War II and come in various forms, including single-stage and dual-stage models. A hydraulic proportional valve, meanwhile, controls the level of pressure in a cylinder or motor. These valves have also been used for a long time and play a critical role in many hydraulic machines.

How Do Hydraulic Servo and Proportional Valves Work?

Typically, a proportional or hydraulic servo valve will receive some sort of pressurized hydraulic fluid from a pump and then transfer it through to a cylinder. Some of these valves have a simple on-off, binary functionality, but they may also have variable levels of control in order to adjust the flow rate with high levels of precision. They're often used in the manufacturing industry for processes like blow molding, as well as in the world of aircrafts, controlling the flow of fuel to the engine.
