Vessel G 1 / 4 " Inlets Air Compressor Parts Pressure Switch With M20x1.5 Mounting Connection
Introduction:
1, P series pressure control can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure.
2, P series pressure controls can start and stop refrigeration compressors and fans of air condensers.
3, P series pressure controls can be used not only in fluoride refrigeration, but also in air and liquid.
4, P series pressure controls are fitted with 3 kinds of changeover switch: a single pole double throw (SPDT), a double pole single throw(DPST) and a double pole double throw(DPDT). The position of the switch is determined by the pressure control setting and the pressure at the connector.
