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 ...

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.

Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

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, ...

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 ...

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