pressure regulator

1. In a fire sprinkler system, a device that limits water pressure, under both flow and no-flow conditions, in those portions of the system where it is probable that the pressure may exceed 175 pounds per square inch (11,400 kPa).
2. A pressure-reducing valve.

pressure regulator

pressure regulator
The pressure is regulated by sending fluid back through the by-pass when it tends to exceed the pre-set datum.
A device that reduces the pressure of the fluid from a high value to a lower value and, thereafter, maintains a constant output. The out pressure of the regulator can be adjusted. This is achieved by bypassing a portion of the fluid back to the inlet side of the pump.
