Trane SWT3277 Pressure Switch 321142-301 This bronze body control valve

This bronze body control valve is rated for hot water

This ball valve is optimized for on/off service but is suitable for throttling and balancing of non-abrasive fluids where flow is between 20% and 100% of capacity

Field Adaptability: Features reversible rotation to eliminate the need for stocking multiple single-direction motor variants

The probe is equipped with factory-applied Teflon (PTFE) sheathing (often referenced in specific high-temp applications as an alternative to PVC) to prevent tracking and false trips caused by vapor-phase condensation or foam buildup
