MANUAL RESET PRESSURE SWITCH

 Egret BLPS-YKM series of manual reset pressure controllers are suitable for overpressure protection of all types of air conditioning and refrigeration systems. When the system pressure is above the rated security pressure, the pressure induction disk within the sensor moves instantaneously, the security disk through a guide rod is driven to the lock location, while the security disk pushes the switch touch point to disconnect through the connected guide rod; when the pressure drops to the rated security pressure below, the induction disks automatically reset, while as the security disk has been at the lock location and cannot be automatically reset, the switch touch point cannot be connected, and the system can return to the normal working condition only by pressing the external button and forcing to push the security disk lock to the switch touch point into the connected state.

Features of Manual Reset Pressure Switch

Egret BLPS-YKM series manual pressure switches using thread quick joint or copper tube, capillary welding connection structure, simple and convenient to meet the needs of different users.

 

The shell adopts plate mounting type (with mounting ears) or line mounting type (without another external fixed installation) two kinds of mounting methods, can be arbitrarily selected by users

 

Sealed double safety disc stainless steel sensor, to ensure that the system will not be switched on and start the machine due to accidental failure of the sensor, especially safe and reliable.

 

The independent automatic disconnection and manual reset double structure design greatly improves the safety and reliability of pressure protection
