Pumps | Dairy Processing Handbook

The most simple flow control is to fit a throttling valve in the pump outlet line. It is then possible to adjust the pump exactly to the required pressure and flow rate. This is the correct method if the pump is used for varying pressures and flow rates. The disadvantage is that throttling is uneconomical when pressure and flow are constant.

Control Valve Sizing For Steam Systems | Spirax …

Control valves can be compared to convergent-divergent nozzles, in that each has a high-pressure region (the valve inlet), a convergent area (the inlet between the valve plug and its seat), a throat (the narrowest gap between the valve plug and its seat), a divergent area (the outlet from the valve plug and its seat, and a low-pressure region (the downstream valve body).

Positive Isolation - EnggCyclopedia

For such systems two block valves are required for additional isolation between operational process side and device requiring maintenance. A bleed is used to drain/vent the fluids trapped between the two block valves. A blind or a spade is used to provide additional positive isolation. Commonly a double block and bleed valve assely is used
