VFD and Minimum Flow Valve - Pump engineering - Eng-Tips

Modulating control valves have an inherent operating characteristic called angeability factor.?The rangeability factor of a control valve is the ratio of the maximum flow to the minimum controllable flow. This characteristic is measured under laboratory conditions with a constant differential applied to the valve only. A rangeability factor of 10:1 indicates that the valve alone can control to a minimum flow of ?/p>

A modulating valve is used for controlling pressure. The government focus on increasing the capacity additions of power plants across the country is the factor that is boosting the demand for cooling water treatment chemicals. In the upstream segment, valves control the flow of crude oil and natural gas from high pressure injection

Modulating Feedwater valves allow for constant incremental adjustments to feed water into your boiler. They come in all types from ball valves, to knife gates, to globe valves and operate off of many types of signals. Some typical applications are 0-135 ohm slide wires from a McDonnell and Miller 7b switch or a 4-20ma signal from a differential pressure transmitter.

Condensate drainage - Recommended Piping. When using a steam modulating control valve with a water heater or unfired steam generator, it is most important to discharge the condensate from the float and thermostatic trap to gravity drain and do not to attempt to lift the condensate above the outlet of the float and thermostatic trap without the use of a properly installed condensate pump.
