  • Technical Feature


    OPERATION:

    The valve is a direct-acting, dual cross-over relief valve in a single cartridge format. When
    pressure at either port exceeds the nominal setting value, flow will be transmitted to the
    opposite port. Back pressure at either port will affect the nominal setting of the opposite
    port on a 1 :1 basis.
    For correlation purposes, pre-set value will be measured at port     ② .Pressure at port ① will
    not exceed ±150 psi from the port     ② value.
