Visual automatic water valve is installed in a new way to make water pipe valve closed loop heating or cooling system, which is a set of valves, globe valves, check valves, filters feature high-tech new valve . Automatic water valve so that the water supply system pressure is maintained at a set value, the valve is installed in the bottom of the filter can prevent the inflow of impurities, air conditioning water valve has a return function to prevent water from flowing back the main channel, the knob can be set by adjusting the outlet pressure, Even when the inlet pressure vary, you can ensure the stability of the outlet pressure, when a state of emergency, the bottom valve handwheel can be completely shut-off valve. Automatic water valve installation instructions 1. Automatic water valve can be installed horizontally or vertically, but not upside down, that is not in the upper plastic knobs. 2. Watch the outlet pressure gauge, adjust the top of the copper hex nut until the system pressure is needed to run 3. It is recommended to set automatic water pressure is higher than the hydrostatic valve 0.3 kg, but the water pressure is lower than the set value required, otherwise there can not normally pay. The automatic water injection valve automatically to the set pressure, water longer. 5 If you need to interrupt the automatic replenishment, you can manually turn off the automatic cut-off valve on the water. 6. If the valve can be replaced or cleaned dirty water valve spool conditioned internal filter to avoid impurities flow into the system, even if water-side pressure changes, but also to stable outlet pressure, emergency handwheel can be completely cut off the flow.
