Bard HVAC 1804-0462 High-Pressure Switch 650/520 PSI

The Bard HVAC 1804-0462 High-Pressure Switch is a safety part that is indispensable for regulating the pressure in HVAC systems. This switch works under the pressure range of 520 PSI to 650 PSI, ideal for high-pressure applications. Its main purpose is to regulate refrigerant pressure, turning on or off the system when the pressure reaches a certain level to avoid harm. When the system pressure reaches the upper limit, the switch turns off the system by tripping the system. This switch is preferred for different HVAC applications such as chillers, boilers, and refrigeration systems.
