Resideo D146M1040 1-1/4" Differential Pressure Regulator Range 0-17PSI

The Resideo D146M1040 is a 1 1/4” differential pressure regulator that maintains a differential pressure across HVAC systems to guarantee the better performance and efficiency. This pressure regulator has a brass valve body and is designed to work on a pressure of 0-17 PSI. Because of its high efficiency even under 230°F, this unit can be used in any HVAC applications. They help in maintaining the various pressures in the system constant thus do away with problems in the system like pump cavitation and energy loss. The connection size of 1 1/4” NPT is easy to connect with other piping systems, and hence it can be applied in residential as well as commercial.
