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 ...

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...

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 ...

3D printing techniques enable quieter, higher performing designs for final control elements. Control valve noise is a problem in many plant environments. The sound is created by very high pressure ...

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, ...

Scaling is one of the most frequently occurring problems in geothermal power plants and can prohibit the control of well flow if it builds in the well or wellhead. At HS Energy on the Reykjanes ...
