which aim to reduce the time spent on filling and checking the water tank, sealing effect and high pressure; using a smaller float control device, which can withstand greater fluid pressure used for waterer bowl automatic bowl tank horse dog cattle water leveler auto fill float valve, durable, corrosion resistance, no deformation, clean and sanitary dimension: the float ball valve has a 1/2 npt pipe thread, this is common in the pipeline world significantly saves more than 30% of the water when cattle drinking, reduces the sewage discharge pressure, water flow, and high efficiency. water faster than the traditional straight-sealed, less splash wide range of use: the sink float valve is suitable for ponds, chickens, livestock pools, aquariums, fish and vegetables, aquaculture, hydroponic reservoirs, and its adaptability is more than traditional metal float valves floating principle: the tank float valve uses floating principle to control the inlet and outlet water switch, to achieve a constant water level effect, saves time and labors on checking manually application: cattle, horse, pig, etc large animals water trough color: white, creamy-white material: plastic size: length: 95mm line port size: 1/2 inch package contents: 3 x float valve only the above package content, other products are not included note: light reflection and different displays may cause the color of the item in the picture a little different from the real thing. the measurement allowed error is +/- 1-3cm
