The sequential Valve Gate Controller is mainly used in valve gate hot runner injection molding system. By detecting the signal of the injection mold machine and meeting the customer’s injection mold needs, it can be adjusted and delayed through locking the injecting and closing at different times and then through opening and closing the valve pin of pneumatic type accurately to make plastic products have no binding line . 1.Applied to voltage and frequency of 50/60Hz 220VAC 2.Time-control precision to the 0.1S 3.The time setting ranges 0S~9999S 4.Input signal :the passive switch signal 5.The output current/W(10A/2200W/240VAC) 6.Form of control output is relay output (AC220V output or passive output ) 7.Slot design is fit for well-known brands of hot runner systems and control box 8.The variety specification: from 1 to 8 9.Connection method: The first 1,2, the second in 3,4 and so on
