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 ...

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, ...

• 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 ...

The Belimo Energy Valve™ revolutionized the industry's approach to pressure independent control valves by combining precise ...

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 ...

ISA recently published Fluid Mechanics of Control Valves: How Valves Control Your Process by Hans D. Baumann, Ph.D., PE — a world-renowned expert on control valve technology who is credited with more ...

The newly unified manufacturer and distributor combines Reliable Automatic Sprinkler’s fire-protection portfolio with ASC ...

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 ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...
