单一的压力开关

Single pressure switches P series pressure controls can be used not only in fluoride refrigeration, but also in air and liquid.It can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure. P series pressure controls are fitted with a single pole double throw (SPDT) changeover switch. The position of the switch is determined by the pressure control setting and the pressure at the connector. Approvals: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
