| The 110570 is a specially designed control line valve that differs from the other valves on this page. Although it looks very much like the 110580 one delivery port (marked "Dolly") is configured for modified flow. This arrangement can be very beneficial in full (pull) trailer or multiple vehicle trailer trains. |
