Hydraulic-over-air relay valves are designed to convert hydraulic-modulated input pressure to a proportional output air pressure. The valves are suited for on and off-highway applications ...

While the engineering community continues to explore the benefits of electric and hybrid vehicles—i.e., the environmental and renewable energy factors—the automotive market is still dependent on ...

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 ...

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 ...
