Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

After all, the best value comes when a product enhances production and profitability. That is why ROSS is pleased to introduce customers to its two latest additions to the ROSS product family—the new ...

Industrial valves are transforming into intelligent, connected systems that can detect and address issues before they escalate. With IoT integration, advanced materials, and proper installation ...

New ZL Series proportional flow control valves from HydraForce Inc. (Lincolnshire, IL) are internally pressure-compensated and operate in two directions. "The valves provide identical flow vs current ...

• Standard solenoid valves pose an ignition danger near hazardous materials. • Valves with pneumatic and magnetic actuators require no electricity, making them inherently safe in hazardous locations.

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 ...

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, ...
