YK Series Extra-High  Pressure Auto-reset Pressure Control

Product specification

◆ Adopt Eng. thread quick connector (copper flare connection) or brass tube welding structure, easy to use and no special installing requirement.

◆ Plugging or wiring connection designed to customerschoice.

◆ Single cut single thrower switch mode and normal open structure..

◆ Security and reliability by adopting fusion welding stainless steel pressure inductor covered by burstproof outer shell made of steel.

◆ Any pressure value within 1305PSI~2610PSI (9~18MPa) can be made based on customers' requirement.

◆ Pre-set pressure parameter before delivery allows direct use without resetting on the customers' site.

Operation Principle

The series of pressure control are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing certain pressure. The electric contact opens with the leader when the diaphragm moves. The switch resets automatically when induced pressure reduces below rated value.


The series of products are specially designed and manufactured for the refrigeration equipment using CO2 as refrigerant, the pressure of this kind of refrigeration system is much higher than that of the normal system. The product also applies to all equipments and toolings with the high protection pressure over 800PSI(5.5 MPa).
