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, ...

Boiler feedwater valves operate under severe service conditions and are subject to premature failure from seat leakage, cavitation, particulates, and frequent cycling. However, once the type and root ...

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 ...
