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 that can withstand greater fluid pressure used for waterer bowl automatic bowl tank horse dog cattle water leveler auto fill float valve, durable, corrosion resistant, no deformation, clean and sanitary dimension: the float ball valve has a 1/2 NPT pipe thread, which is common in the pipeline industry significantly saves more than 30% of water when cattle are drinking, reduces sewage discharge pressure, provides steady water flow, and operates with high efficiency; fills faster than traditional straight-sealed valves with less splash wide range of use: the sink float valve is suitable for ponds, chickens, livestock pools, aquariums, fish and vegetable systems, aquaculture, and hydroponic reservoirs; offers greater adaptability compared to traditional metal float valves floating principle: the tank float valve uses the floating principle to control the inlet and outlet water switch, achieving a constant water level effect, saving time and labor on manual checks application: cattle, horse, pig, and other large animal water troughs 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 to appear slightly different from the real thing. the measurement allowed error is +/- 1-3cm
