Specification

DESCRIPTION
When the pressure of port one reaches the valve setting ,the pilot spool starts to open,Next the main spool opening because of the pressure drop between inside and outside of main spool, Realize overflow from port one

 to port tow , This pressure is the first level setting one, When a certain pressure is applied to port three , The overflow pressure from port one to port tow  will increase accordingly, This pressure is the secondary.
