There are many different types of systems and applications that use a pneumatic pilot valve. These valves come in many different sizes and options, including the choice of material for the valve.
In general, a pilot valve is a small valve that is used to help to control the feed or the flow to another type of valve. The role of the pneumatic pilot valve is to control high or low air pressure in the system in an easy to manage way. As the pilot valve is smaller, it is easier to operate than a larger valve and requires less air flow. This makes a pilot valve a great choice for areas where air flow needs to increase, and where there is lower power.
Basic Considerations
Like most valves, the pneumatic pilot valve is selected based on the specifics of the system and the needs of the application. These valves tend to have a 90-degree body configuration as a standard valve, and they can operate as a two or three-way exhausting or non-exhausting valve. Some companies offer limited options in configurations and pilot valve designs, while others offer a more comprehensive selection.
Most of these valves are designed to be normally closed, but they can also be configured to be normally open based on the specific system and application. They can have different connectors, various pilot actuation force levels as well as various ends on the outlet ports for the pneumatic pilot valve.
As most of these valves are used in critical types of applications and system, they need to be manufactured from the types of materials that can stand up to the demands of the system and continue to work effectively. Most are made of nickel plated brass with the option to custom configure the pilot actuator port and the inlet and outlet ports to meet the requirements of the system.
