Water pressure of the valve apply to: 0.003-1 .0Mpa, Hydrostatic pressure of water outlet: 0.004Mpa +5%.Escape pipe should be 30 cm higher than water heater. The valve's water level has been adjusted before they leave factory, use the screw bolt in the upside of the valve can adjust it again if needed, and water valve will rise when tightening the bolt and drop conversely. It is a normal phenomenon if there is a little spilling water when the solar water heaters vent pipelines in light heating. To prevent blockage, the pipeline should be rinsed out before installing the valve. Double-pipeline mode has built-in check valve, single-pipeline mode is configured using articulated water-meter check valve, it can prevent reflex water when the water stops. As long as installing the check valve in the articulated water-meter position, this has solved the trouble of the users that can't install the check valve inconveniently.
