Servo-Assisted Solenoid Valves

Have you ever wondered how machines and equipment are able to control the flow of fluids with such precision? One technology that has made this possible is servo-assisted solenoid valves.

What is Meant by Servo-Assisted?

A servo-assisted solenoid valve is a type of valve that uses electrical signals to control the flow of fluids. The term “servo-assisted” refers to the mechanism that controls the valve. It uses a combination of a solenoid and a hydraulic or pneumatic mechanism to operate. This allows for precise control of the valve, even in high-pressure applications. 

The servo-assisted mechanism provides additional force to the solenoid, making it easier to operate and more responsive to changes in the electrical signal.

Why use a Servo-Assisted Solenoid Valve instead of a Direct-Acting Solenoid Valve?

Using a servo-assisted solenoid valve instead of a direct-acting solenoid valve can provide precise control and improved energy efficiency. The assisted design allows for greater accuracy and responsiveness in controlling the valve, making it ideal for applications that require a high degree of precision.

Additionally, the servo-assisted valve can operate at lower pressures than a direct-acting valve, which reduces the amount of energy required to operate the valve. This can result in significant cost savings over time, particularly in applications where the valve is required to operate frequently or continuously.

Are Servo-Assisted Solenoid Valves Known by any Other Names?

Servo-assisted solenoid valves are also commonly referred to as proportional solenoid valves. Other terms used to describe these valves include proportional control valves, electrohydraulic valves, and electro-pneumatic valves. Despite the different names, they all refer to the same type of valve that uses a solenoid to control the flow of a fluid or gas.

What Industries use Servo-Assisted Solenoid Valves?

Servo-assisted solenoid valves are commonly used in industries that require precise control of fluid flow. One such industry is the automotive industry, where these valves are used in fuel injection systems to precisely control the flow of fuel into the engine.

They are also used in the medical industry, particularly in equipment such as ventilators, where precise control of airflow is critical to patient safety and well-being.

In the aerospace industry, servo-assisted solenoid valves are used in hydraulic and pneumatic systems to control the flow of fluids and gases, ensuring the safe operation of aircraft.

Other industries that use these valves include food and beverage processing, HVAC systems, and industrial automation.


In conclusion, servo-assisted solenoid valves are a game-changer in the world of fluid control. With their precision, reliability, and efficiency, they’re the perfect solution for any application where accuracy and consistency are key. 

Whether you’re in the medical field, the automotive industry, or anywhere in between, these valves are sure to make your life easier and your processes more effective. So why wait? Start exploring the world of servo-assisted solenoid valves today!
