Refrigeration control valves for industrial refrigeration systems have been an important system component since the 1920s. When a control valve fails, the result can be as significant as a more costly ...

Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

Among the various types of valves on the market, ball valves are critical in high-pressure systems, enabling precise fluid control in industries like power generation, chemical processing, and oil and ...

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, ...

Food and beverage applications must meet a variety of process temperature and pressure control requirements to maintain the tight temperatures that ensure product quality and safety. Selecting the ...

Intro: A graph of your car’s idle speed shouldn’t resemble architectural plans for a new Cedar Point roller coaster. Once the car warms up to normal operating temperature, it should run in a smooth ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...

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 ...
