Pilot Operated

Pilot operated and air operated spool valves are two different types of control valves used in fluid power systems.

Pilot operated spool valves are controlled by a small, auxiliary fluid signal that is used to move the spool and control the flow of fluid through the valve. The auxiliary fluid signal is amplified by the main fluid pressure, allowing for precise control over fluid flow. These valves are often used in applications where fast response times and high flow control precision are required.

On the other hand, air operated spool valves are controlled directly by compressed air that is supplied to the valve. The compressed air moves the spool and changes its position, allowing fluid to flow through the valve. Air operated spool valves are typically used in applications where quick response times are not a concern and cost is a major consideration.

In summary, the main difference between pilot operated and air operated spool valves is the way in which they are actuated and the level of control precision they offer.

These spool valves are ideal for use in sensitive areas such as clean rooms and pharmaceutical and food processing sectors, where protecting the environment is of utmost importance. With a focus on quality and durability, the ASCO Series 551 552 553 Spool Valves are a reliable choice for your industrial needs.
