Dwyer Instruments DA-7031-153-2 Pressure Switch 326058-755 Contractors can rely on this

Contractors can rely on this resilient seated valve for bi-directional isolation and consistent on-off or modulating service in chilled water

this motor and blower housing unit maintains the precise static pressure required to trigger the pressure switch

applying a high-quality thermal conductive compound between the probe and the pipe surface significantly improves response time and accuracy

a faulty relay or logic gate on the control board is often the culprit

Exceeding this limit can damage the internal diaphragm and affect calibration
