Commonly installed in air conditioning units, heat pumps, refrigeration equipment, and packaged HVAC systems requiring a 1\/4-inch pressure connection. HVAC service technicians use this pressure control for replacement, repair, preventive maintenance, and restoration of refrigerant system safety controls.
