type of operation, e.g. electrical, pneumatical or manual. Directional control valves are often characterised by two numbers: the number of main ports followed by the number of switching positions.

Air valves allow metered flow of fluid in one or both directions. Many of them allow for free flow in one direction and reduced or metered flow in the reverse direction. They are used in pneumatic ...

The compact design of the VSNG6 solenoid-operated directional-control valves features reduced solenoid dimensions, making the valves suitable for mini-power pack, mobile, and agricultural applications ...

Hydraulic circuits are comprised of cylinders, valves, pumps, and are connected via hydraulic pipes and tubes. The complexity of these components are difficult to represent fully so hydraulic symbol ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
