The Fisher R622-1/2-13-20 Regulator is a pressure control component that manages gas flow regulation with a 1/2" NPT connection, 1/8" orifice, and 13-20" WC pressure range. The component adjusts gas pressure levels by responding to flow changes and maintaining the required output for heating operation. This regulator works with HVAC systems such as gas heating and boiler units to assist with fuel pressure management and control. Attached along the gas supply line, it provides steady pressure delivery and proper regulation between fuel source and burner sections.
