In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...
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 ...
Pinch valves, the simplest valve design, include any valve with a flexible elastomer body that can be pinched close to cut off flow, using a mechanism or fluid pressure. They are linear motion valves ...
Steam valves are used to control the flow and pressure level of steam and heated water vapor. Steam is used in a large number of industrial applications. It is used for powering turbines to generate ...
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 ...
Oxford Flow has secured an order valued at nearly $1 million USD for its ES stemless axial flow valves. The order from bp is a significant milestone in Oxford Flow’s expansion in the U.S market, and ...
• 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 ...
Karl Benz is typically credited with designing and building the first automobile powered by an internal combustion (IC) engine, but it was almost 80 years earlier, in 1807, that a Swiss by the name of ...
