How can it Work?
The water that enters in the house from municipal's water source is in really high pressure. That is the reason why we must use Pressure Reducing Valve to modulate the pressure of plain water.
It keeps the pressure in this manner which is not dangerous for our expensive equipments. It has been made with tough and long-lasting material to ensure that it could simply resist using the high pressure force it's always under.
A spring actuated valve system, which can be constructed inside the PRV, can be used to handle the pressure in the machine. This spring actuated valve system is linked to diaphragm. The diaphragm function will be to control the stream of liquid in the pipe line. It meticulously keeps the preset pressure.
The water that comes from municipal's water source pushes against the diaphragm as well as the spring's work would be to drive the diaphragm back another way.
You may also increase or reduce the water pressure as per you needs. To do so first you must loosen the lock nut. After losing the nut, turn the screw clockwise in increment place to raise the water or in the event that you would like to reduce the pressure, just turn the screw counter clockwise in increment position. Ensure that you tighten the nut after reaching your desired water pressure.
