Product Specifications

 

1.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.

 

2.Plugging or wiring connection designed to customers’ choice.

 

3.SPST connection,normal open or normal close structure designed to customers’ choice.

 

4.Security and reliability by adopting fusion welding stainless steel pressure inductor and full-tight connection.

 

5.Any pressure value within -14.5~750PSI(-0.1Mpa~5.17Mpa) or extra high pressure switch (more than 800PSI)can be made based on customers’ requirements.

 

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