Product Specifications
Adopting Eng. Thread quick connector (copper flare connection) or brass tube welding fitting structure, flexibly setting, easy to use and no special need for mounting and fixing.
Plugging or wiring connection designed to customers' choice.
SPST connection, normal open or normal close structure to customers' choice.
Security and reliability by adopting fusion welding stainless steel pressure inductor and full air-tight connection.
Any pressure value within 3~700 PSI (0.02Mpa~4.8Mpa) can be made based on customers' requirement.
Pre-set pressure parameter before delivery allows direct use without resetting on the customers' site.

Operating 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 or closes with the leader when the diaphragm moves. The switch resets automatically when induced pressure reduces below rated value.

Application
The series of pressure control is used to the high, low pressure protection of some refrigeration system like residential, commercial, automobile air-conditioner and ice maker etc. It can also be used to hydraulic pressure and steam pressure control system of all kinds of air compressor, equipment or tool and agricultural machine.
