What are Moog Servo Valves?

Moog Servo Valves are used in the automotive and aerospace industries, as well as countless other applications, because they’re reliable, accurate and easy to use. But what are they? Read on to find out! Moog Servo Valves operate using input signals which move parts within the servo valve using air pressure or hydraulics. When an input signal moves the part inside of the valve, an output signal can be sent either to open or close a load port.

The Parts Of A Servo Valve

A servo valve consists of three parts: a small orifice, a spring and an actuator. The combination of these three elements work to regulate and control pressure. The orifice regulates how much fluid is allowed to pass through at any given time. A spring provides pressure, moving the spool back and forth against a stop, opening and closing within milliseconds to ensure constant pressure flow. An actuator controls how far open or closed it can go at any one time.

The Benefits Of A Servo Valve

A Servo Valve is a very high-tech product used in automobiles to control power steering, emissions, and safety. Although moog servo valves may look fairly straightforward, they are made with many advanced components that make them both reliable and powerful. It’s one of those high-tech products you can easily overlook but will be grateful for when you need it most. Here’s how they work

How To Troubleshoot A Leaking Moog Servo Valve

The first step in learning how to troubleshoot a leaking moog servo valve is to determine where it is leaking. You will be looking for small, pinhole-sized leaks that can appear on any of its seals and/or areas where metal meets metal, such as between components or around nuts and bolts. After you’ve determined where it is leaking, use a pencil eraser to remove any buildup around those seals.

How To Prevent The Seals From Failing On A Moog Servo Valve

Moog servo valves are essential in controlling a number of different devices, including power steering and brakes. If your seals start to fail on your Moog servo valve, you’ll have to replace it quickly because if they completely give out, you could end up with a much larger issue on your hands. This guide will teach you how to prevent that from happening.
