Description
The Sensus-Gas Division 121-12-2 1/2 Gas Pressure Regulator is used for the regulation and maintenance of gas pressure as a combustion requirement. It controls the flow of incoming gas by the use of a spring-loaded diaphragm mechanism in HVAC systems like boilers, furnaces and gas-fired units with a 6″ to 14″ WC outlet range and 2-1/2″ connection size to allow constant pressure and compatibility with lines. It is connected to the gas supply piping and is responsive to the downstream demand to ensure a constant supply. It facilitates consistent burning, consistent pressure equilibrium and consistent heating operation.
