Precise Calibration: Factory-set at -0

Common Questions & Technical Support Can this kit be used on a step-opening gas valve

The valve is CSA listed and meets ANSI Z21

The thermostat will open the electrical circuit when the sensed temperature reaches 105°F (to prevent overheating) and will close (reset) once the temperature cools to 73°F

Natural gas requires a larger orifice diameter to account for the difference in energy density and manifold pressure

Danfoss 020-1012 Check Valve Precise Calibration: Factory-set at -0The Danfoss 020 1012 (NRV 12s) is a professional grade, straightway HVAC check valve designed to maintain unidirectional flow in liquid, suction, and hot gas lines. Featuring a 1 2" ODF solder connection, this robust component utilizes a built in damping piston, making it highly effective for discharge lines where compressor pulsations are common. Its brass body and copper connections allow for a maximum working pressure of up to 710 psig (49 bar),
