The proportional hydraulic control valve precisely controls the output flow and the input current to be applied to the electromagnetic variable internal port. The miniature direct acting PC3 valve has been tested for 100 million cycles and has a full range of response speeds, quiet operation, low hysteresis, and consistent flow "gain". This is an ideal choice for hydraulic valves in the high-tech market segments such as analytical instrumentation professional applications , test and measurement, medical equipment, process control, and automation in the factory is a dynamic pressure or speed controller and actuator cylinder.Control Valve, Flow Control Valve, Hydraulic Control Valve, Proportional Directional Control Valve
