Trane SWT3277 Pressure Switch 320720-756 This specific model is primarily

This specific model is primarily designed for high-pressure R-410A systems

requiring no special tools for component extraction or seating

especially on heat pump changeouts or low-ambient cooling setups

This valve is utilized in atmospheric burner setups where standard modulation valves cannot provide the necessary higher outlet pressure for specific manifold requirements

is a heavy-duty 2-way normally closed (N/C) control solution built specifically for the demanding conditions of commercial and industrial steam applications

Trane SWT3277 Pressure Switch 320720-756 This specific model is primarilyFor high pressure protection in commercial and industrial HVACR systems, the Trane SWT3277 Pressure Switch (also identified as Trane SWT03277) is a critical SPST high pressure switch designed for overpressure protection. This single pole, single throw component is engineered to maintain system integrity by monitoring refrigerant line pressures. The switch features 650 PSI open and 500 PSI close settings, providing a precise pressure switch cut out to
