How to Choose a Control Valve? - Instrumentation Tools

2020-10-23 · When choosing a control valve for a process, there are many things that must be considered, including the valve's flow characteristic, its size, noise, the potential for cavitation or flashing damage, body and trim materials, actuator size and type, and its dynamic response to changes in the control signal.. The selection primarily depends upon the application and the pressure and

Size Boiler Feed - MathWizard™ - Shipco® Pumps

For boiler feed pumps running ON/OFF, the pumps are controlled by a boiler level controller. The receiver size on boiler feed units is typically based on the total system load of all boilers fed by the boiler feed unit with 20 minutes GROSS storage. The size of boiler feed receivers are expressed in gross gallons.

Spring selection for safety valve - Practical Machinist

2010-4-1 · The valve size should be determined using the maximum heat input (based upon, for example, fire-side boiler surface area), not upon an heuristic or the fact that others are using a 7/16" valve. If you scale both boiler and valve (including valve orifice size) linearly from the prototype, you could have a valve that is over-sized. On a scale
