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.

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 ...

BBB CoreCap reinvents the tire valve. More airflow & durability than Presta. Better compatibility than Schrader. And no extra cap needed!

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, ...

Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Over the course of hot rodding, one of the more debatable upgrades has been swapping camshafts--especially in modular engines. Given the Two-Valve's complexity and cost of buying two camshafts, the ...

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

"I want big power," was the comment from Editor Smitty to Mike Dezotell and myself during a brainstorming meeting last month. The power he was referring to is the little supercharged Two-Valve bullet ...
