Description
The Sensus-Gas Division 243-8-IRV-2 pressure regulator valve is intended primarily for use in HVAC systems. By controlling the pressure of natural gas supplied to gas-fired equipment like boilers and furnaces, it is essential to their safe and effective operation. This regulator has two holes: one for the main gas line to attach to 2 inches and another for the gas appliance to attach to ½ inch. It is designed to withstand pressures between 12 and 28 inches of water column, which is a typical low-pressure system measurement unit for gas pressure. The Sensus-Gas Division 243-8-IRV-2 works by keeping the downstream pressure constant, independent of upstream pressure variations.
