When it comes to servo valves there are many different kinds out there that can either help, or hinder the flow of different materials through the valve. Most Parker valves are used in different things like electrohydralic systems in which they are used to control the flow of different gases and liquids throughout the device, or mechanism they are attached to.
The most prominate place you would find Parker valves are on different hydraulic systems, and different systems in the military, the military force is the number one consumer of different things like servos, and servo valves they use them on different things like anti-aircraft guns, and different devices that they use for defense, and military coordination.
Finding a Parker Valve
Its really difficult in trying to find a Parker servo valve, many people look all over the place and most of the time they are very difficult to find because they are not used by everyone on a daily basis.

You just have to do some research on the many different servo valves and the different kinds that you may need, because there are many different types of valves out there.
Types Of Servo Valves
There are many different types of Parker servo valves out there, ranging from different ones that regulate gases, liquids, steam, different hydraulics, and many different other substances. The servo valve regulates the flow and the different pressures that the fluids are gone through, and at, many different valves regulate different substances, and different pressures at different levels, you just have to do some research to see which one you need, for your project.
