Specification:Material: Nylon PA66+Food grade rubberSize: 72x50x70mmWorking pressure range:1-10KG (0.1-1MPa)Applicable Medium: clean waterApplicable Medium temperature: ≤70°Resistance to high temperature medium temperature: 70°~120°Package Contents:1 x Water Level Control ValveNote:Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bidDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!Note:This production belongs to the liquid level control valves.When installed, the float must be vertical. if you need to install from the top , a Elbow needed to connect the float valve and the inlet line.Firstly, the feed line should be fixed in horizontal plane and then connect the automatic water level control valve on the water inlet according to the standard.The main water inlet should be lined with the control valves' Normal Diameter.When using, the globe valve should be all open.If two valves are installed in the same pool, the two valves should be held in the same horizontal plane.Before installing, please clean the impurities in the pipes in case of blocking.If the water quality is not good, then the valves need to be maintained properly.If the users find the time of adding water becomes longer, he can just upload the water inlet and make it washed.When the pool or tank water levels fall, the valve body will sink down and then the forerunner of the control valve will be opened.As the pipe water pressure affects, the seal face of control valve will be opened.Finally the water comes out and vice versa.
