Description
The Maxitrol 210E-1 1/2 is a gas pressure regulator valve used in HVAC systems, specifically for natural gas or propane. By controlling the gas pressure supplied, it protects boilers and other gas-fueled machinery. Regardless of variations in the upstream pressure, the regulator functions by keeping the downstream outlet pressure constant. This is accomplished by the use of an internal spring that responds to changes in pressure to open or close a valve. The spring is squeezed to lessen the valve’s opening and restrict gas flow when the inlet pressure rises above a predetermined level. This guarantees a constant gas pressure for the apparatus to which it is attached.
