The VED03M direct-operated four-way proportional-control valves conform to NFPA D03 and ISO 4401 mounting standards. The valves control direction and flow rate based on the current supplied to the ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

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 ...

Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

With sliding ceramic plates (instead of rubber seals) that form a tight seal, Ceram ISO 5599-1 pneumatic directional-control valves are tolerant of dirty air and harsh conditions. With sliding ceramic ...
