Information

 Product  Speci?cations


◆ Adopt Eng. thread quick connector (copper ?are connection) or brass tube (incl. capillary)

welding connecting structure, easy to mount for different needs.

◆ Board-assembly (with mounting ears) or wire-assembly (no need for separate ?xing) can

be chosen for outer shell assembly.

◆ The air-tight bi-security disc and stainless steel sensor ensure that the switch opens instantly automatically under the pressure and cuts off the connection between the switch

contact and the pressure inside the system. The system will not be able to start up the machine by accidentally actuating the pressure switch, which is safe and reliable enough to prevent the machine from damaging.

◆ The independent structure design of auto switching off and manual resetting enhances the

maximum security and stability for the pressure protection.

Operating Principle

◆ When pressure inside the system is higher than rated safe pressure, the sense disc starts to function instantly, resulting in pushing the security disc to the lock position by the rod and cutting off the switch by security disc through connecting rod at the same time. When the pressure reduces, the sense disc resets automatically while the security disc can’t reset because it is at the lock position,

hence the switch can’t cut in. The system will reset to normal status only when pressing the outside button to push the security disc

forcibly to unlock in order to cut in the switch.

Application

◆ The series of switches are used to all air conditioning and refrigeration systems that require special pressure protection and broad

range of extra-high pressure protection for the pressure systems of variety of tools and equipments. They can be directly installed on

the pipeline or on the control panel based on the equipments situation.
