The Basics Of A Pneumatic Pilot Valve

by | Apr 13, 2018 | manufacturing

There are many situations where a high pressure or high flow system would be very different to operate either manually or automatically due to the flow and pressure. It would become very challenging to shut off the air flow through the system due to resistance from the high flow or high pressure.

In these applications, a pneumatic pilot valve can create an easy to operate a valve which then controls the flow of air through the large system. Through manipulating the pilot valve, either manually or through automated control, the system can be easily controlled.

Configurations and Options

Often a pneumatic pilot valve is used when there is a need for immediate and rapid control of the flow through the system. They are often designed with a variety of different configurations, including a two or three way exhausting or non-exhausting flow as well as the valve in the normally closed normally opened positions.

Each of the pilot valves will also be rated for the pilot actuation force. Most will be configured to be a ninety-degree angle on the valve, with a 35-psi pilot actuation force rating.

There are also options for pilot actuated valves that are designed to be mini valves. These may also be known as mini needle valves. They will have various configurations for the body as well as the inlet and outlet on the valve. These types of mini pilot actuated valves will be rated for a maximum operating pressure in psi for the system.

A pneumatic pilot valve can also be used as part of a master shut-off assembly. These types of valves need to be carefully designed and selected, including the choice of materials and the installation method, to ensure they provide the application requirements needed for the systems for the safety of operation.
