A regulator is simply a valve with a preset pressure point that causes the valve to open and close. A pressure sensor (a diaphragm with an adjustable spring) is on the side of the valve that the pressure you want is on. When the desired pressure (we will use 50psi) is reached, it causes the diaphragm to expand against the spring.The diaphran is connected to the valve and when it expands, it closes the valve, letting no more pressure to build. when you flush a toilet or turn on the sink, the diaphragm contracts opening the valve wider and wider until enough water is flowing in to raise the pressure expanding the diaphragm to close the valve.
the diaphragm is just like a ballon, the more pressure, the more it expands.
the set screw on most regulators puts more or less pressure on the diaprham raising or lowering the amount of pressure needed to move the diaphragm enough to close the valve.
do not confuse the regulator with the pressure switch on a pump system. they are not the same. the job of the regulator is to keep constant pressure in your system. the pressure switch on pumps works about the same but has two preset pressures. the first to turn a pump off when the desired pressure is reached and the second to turn it back on. the off pressure is always higher then the on pressure by about 10psi or your pump would be constantly turning on and off.

What a pressure regulator valve?
A pressure regulator is a control valve that reduces the input pressure of a fluid to a desired value at its output.
Is it true that pressure reduces valve?
There are pressure regulator valves that exist. The purpose of these pressure regulator valves is to cut off the flow of a liquid or gas when the pressure within the valve reaches a certain level.
Why do some homes have a water pressure regulator installed whilst some don't?
The only time you would need a Pressure Regulator Valve is when the pressure from your supply is too high. The Valve will lower the pressure to a usable pressure and keep it constant.
What is the definition of a servo pressure regulators?
it is a regulator of servoing and pressure control to oversee the valve
Where is the fuel pressure regulator valve in 2001 Chrysler town and country?
The fuel pressure regulator is part of the pump module in the fuel tank.
What is the purpose of a pressure regulator?
Purpose of a pressure regulator is to match the flow of gas through the regulator to the demand of gas placed upon the system. It is a valve that can automatically cut off the fluid of a liquid at a certain pressure.
What is the difference between a pressure regulator valve and a pressure reducing valve?
Pressure reducing valve reduces the pressure of fluid upto a predetermined pressure in this case downstream pressure will be obviously lower than upstream pressure but in case of pressure regulating valve it will regulate the pressure( either increase or decrease) depending on the requirement of system at that time.

By a pressure regulating valve- or regulator.

Slam shut valve?
Slam Shut-off valve is installed immediately after the filter & prior to the Regulator. It normally remains open, incase the outlet pressure of the regulator exceeds the permissible limits, the slam shut off the valve senses it through the impulse line & immediately shuts off the flow to the downstream. When the regulator is repaired, the slam shut off is to be open manually by pulling the knob. Once the flow starts through the shut off valve it will remain open till the outlet pressure of the regulator is within limits.
