  • 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.
