     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.

    The minimum vacuum pressure can be 15in.Hg

    Any pressure value within 15in.Hg~8PSI (-0.1~0.05MPa) can be made based on customers'


    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.


    These pressure controllor are used to protect the low pressure system of the refrigeration equipment which pressure is negative.(under normal atmospheric pressure). It can also be used for control of pneumatic, hydraulic, lubricating oil system.
