Automatic watering system / Zamadi Abdul Ghani

Directional control valves manage the flow path of the fluid in the system. They function to stop, start, check, divert, shuttle, divide proportionally, and by other means direct the flow of of fluid in one, two, three, four, or more flow' paths or ways. Pressure and flow compensation, in addit...
