(Reconditioned) The UC4MR hydraulic controller was designed to meet changing application trends. The greater variation in temperature and pressure seen in today's market demand much more from the valve design. The first steps of improvement are to regulate the area of greatest variation (down main speed). The UC4MR will allow the user to have direct adjustment control of loaded and unloaded down main speeds without applying a load. Coil and coil assembly not included with exchange. Core charge will be billed on initial invoice. Old rebuildable core from the job must be returned to Maxton within 90 days to be eligible for a core charge credit. JACK port is located to the left - TANK port straight across to the right - PUMP port at the bottom. Solenoid - Square pattern.
