What lurks beneath the surface? What is underneath, where eyes cannot see? Is it something valuable? Is it something old? Is it some treasure or something frightening to behold? These are common ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

We report the design, fabrication and characterization of a microelectromechanical systems (MEMS) flow control device for gas chromatography (GC) with the capability of sustaining high-temperature ...

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, ...

The High-Flow Namur Valve, built with an anodized aluminum body, a stainless-steel spool, and brass internal parts, is designed for direct mounting to pneumatic actuators. The High-Flow Namur Valve, ...

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...

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 ...

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.

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...

FLUID POWER CONNECTORS & COMPONENTS ULTRA-MINIATURE PRESSURE COMPENSATED FLOW CONTROL VALVE WITH LOW FRICTION DIAPHRAGM, BESWICK ENGINEERING CO. INC. Some applications need flow control valves that ...

Bessemer invested in Leonard Valve in 2019 alongside third-generation owner, Niles Wilcox. During Bessemer’s ownership, Leonard Valve expanded its digital and thermostatic mixing portfolio and ...
