Adjustable arm: The float valve has an adjustable arm that can be adjusted over 180 degrees to adapt to different water levels. No power source or pump required, hand tight for leak-free operation. Material: The mini float valve, with adjustable arm, is made of plastic and brass, more stable and will not rust, has good water inlet control function, providing a good experience. Dimensions: The float valve uses 1/2 NPT pipe threads; this is common in plumbing and has thread sizes of approximately 1/2 inch with standard washers to eliminate leaks. The applicability exceeds that of traditional float valves. Wide range of applications: Tank float valves are suitable for ponds, chicken coops, livestock ponds, aquariums, aquaponics, aquaculture, and hydroponic reservoirs, and are more adaptable than traditional float valves. Packing quantity: 2 packs of water tank float valves, designed to reduce the time of water filling and checking the water tank, sealing effect and high pressure; adopts a smaller float control device, which can withstand greater fluid pressure. The water level floating principle of the float ball is used to control the water inlet and outlet switch to achieve a constant water level effect, keep the water volume sufficient, and the water quality is always clean. Cattle drinking water is significantly saved by more than 30%, reducing sewage discharge pressure. Colour: Photo Color Material: plastic + metal Package Contents: 2 x Float valve
