VC-1195A valve controller allows for control of one or two dispensing valves. When dispensing medium to high viscosity materials using a valve, the normal spring return action may be too slow. To speed up the return closing cycle and to eliminate dripping it is recommended to use this controller to control both the ON and the OFF action of the valve. Controller greatly enhances the performance of any valve designed for a 4-way operation. It is recommended for all automated/robotic dispensing applications using the 790 HP series valves.
