Rheem-Ruud 47-102478-01 Low Pressure Limit-Low Ambient Control A/R 250PSI-Open 450PSI-Close

The Rheem-Ruud 47-102478-01 Low Pressure Limit-Low Ambient Control is an indispensable part of HVAC systems since it is intended to stabilize the operation of the equipment. This control device controls the pressure in the system and it opens at 250PSIG and closes at 450 PSIG to avoid low or high pressure conditions. It has a burst test pressure of 5000 PSIG to make it strong enough to withstand pressure to suit its use in different conditions. Measuring 36” in capillary length and connecting with a sweat connection of 3/32”, this control is portable and can be incorporated into different HVAC systems. It has an automatic reset function which makes its maintenance easier and also brings convenience to the users. This low pressure limit control is one of the most common controls found in HVAC systems.
