These hydraulic-over-air relay valves are designed to convert hydraulic modulated input pressure to a proportional output air pressure. Single input design provides one hydraulic pilot port to control ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

The cascading bypass system is perhaps the most common design for managing high-pressure steam in a combined-cycle plant. It is the hot reheat (HRH) bypass valve actuator that defines the valve’s ...

The best controllers and software can't overcome a poorly designed hydraulic system. Global competition ensures that plant operators face the neverending task of making equipment more productive. This ...
