1pc Water Pump Well Parts Double Pole Adjustable Pressure Switch 220VAC Features: This pressure regulator is specially used for Water Pump Automatically Turn On/Off. The default pressure range is 0.14-0.28mpa if lt pressure; 0.14 ± 0.02mpa,Controller is connected; If the pressuregt; 0.28 ± 0.02MPa, the driver is disconnected. The upper and lower pressure thresholds of the switch can be adjusted within the adjustment range. The controller has 2 springs to adjust the pressure threshold, easy to adjust and accurate. It automatically turns the pump on when the pressure is less than the set switch threshold and automatically turns the pump off when the pressure is more than the set threshold.
