Maxitrol 210DZ-1 1/2 1-1/2" Zero Governor Regulator 5 PSI Max

The Maxitrol 210DZ-1 1/2 1 1/2 Inch Zero Governor Regulator is a pressure regulator used in a variety of HVAC (Heating, Ventilation, and Air Conditioning) applications. It maintains a steady pressure and controls the gas flow to gas-fired appliances to guarantee safe and effective operation. The regulator operates by dividing the pressure at the entrance and outlet using a diaphragm. The diaphragm presses up against a spring as the inlet pressure rises, opening a valve and letting in additional gas. On the other hand, the spring pushes back to close the valve and limits gas flow when the pressure drops. Regardless of changes in the supply line, this device keeps the gas pressure constant, avoiding excessive pressure building and possible safety risks.
