to maintain oil-water interface
-to maintain a back pressure in the purifier -to control water flow through water port outlet -to control discharge of oil flow rate
Maintain the osmotic pressure of the blood
Back pressure regulating valve is used in ammonia refrigeration plant to maintain the minimum pressure in the evaporator coils. It helps in preventing ice formation / choke upin the PHE chiller.
If you have water pressure and wish to maintain it, do not cause flow in the line, which will reduce pressure due to friction. To keep pressure up, reduce friction by increasing the line size or eliminating some other restriction. To maintain water pressure in the line, it might have a pressure transmitter and Booster pump to maintain the set Pressure in the network & I disagree the above answer to maintain the pressure we shouldn't increase the line size by reducing the line size we can increase/Maintain the pressure to overcome the losses in the Network
To maintain fuel pressure at the fuel rail, for fast start up.
veins have valves that prevent back flow, and I believe the pressure within circulatory system prevents back flow.
with a pressure tank and pressure switch
when two refrigerated spaces are severed by only one compresser & condenser but need to be maintained at different temps. a back pressure regulator comes into play. The back pressure regulator will be installed on the outlet of the refrigeration system to maintain a minimum back pressure in the evap coils. Since pressure is directly related to temp. then the temp. desired can be maintained by the pressure you set.

To maintain the pressure of the water line it serves.
The function of Lock ring or lock nut in the purifier is basically to the parts in the purifier together.As the lock ring is tightened the bowl is compressed ,in turn compressing the disc stack.The disc stack pressure is very important and the lock ring should never be overtightened. The lock ring usually has a left hand thread if the purifier turns clockwise as vice versa to prevent it from slackening during operation.
