Flow is controlled by either throttling or diverting it. Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through ...

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 ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

The DV Series bidirectional high-flow electronic valves offer flows to 100 liters/min. The precision-built, two-way valves use a patented valving principle and come in a variety of voltage, connector, ...
