Let’s start with the basics.
What is a pressure regulator?
A pressure regulator is a normally-open valve used to regulate or reduce undesirable, high upstream pressure. The pressure regulator must be installed at the START of a system, before any pressure-sensitive equipment.
The valve is held open by springs, and a screw that sets spring force. When outlet pressure exceeds the setpoint, the valve will close. When the valve closes, pressure is reduced downstream.
