    DOT-7000 Series Dual Orifice Trap

    Dual Orifice steam traps are ideally suited for use on shipboard steam systems. The Dual Orifice steam trap is intended to perform with shipboard steam systems where steam is created from demineralized or purified water. The water used onboard does not contain minerals and impurities typically found in land-based steam systems.
