This float valve is a tank-mount style with an adjustable arm, and is made of PVC with 18-8 stainless steel hardware. The valve has a 0.093″ orifice and its estimated rate of flow is 1.3 gallons per minute (gpm) at 40 pounds per square inch (psi) and 1.5 gpm at 60 psi. The valve inlet has 3/8″ NPT male extended threads with a sealing washer and jam nut for mounting through a tank wall, and the valve outlet is free flowing. The valve inlet includes a compression fitting for use with 3/8″ tubing. The valve is made of National Sanitation Foundation (NSF) approved PVC (polyvinyl chloride), its replaceable seals are made of TPE (thermoplastic elastomer) for durability and chemical resistance, and its hardware is made of 18-8 stainless steel for corrosion resistance. The valve has a 1.5″ in diameter and 4″ long polyethylene float attached to the adjustable shutoff lever arm. This float valve is suitable for use in a variety of applications, such as fountains and livestock water tanks.

Float valves use a rod and float ball attached to a valve shutoff lever to control flow in or out of a tank. The float ball rises or falls with the level of liquid in the tank, changing the angle of the valve shutoff lever. When the angle of the valve lever changes sufficiently, the valve opens or closes. Float valves are rated according to the volume of liquid that can flow through them at a particular pressure to ensure the tank can be refilled as quickly as it is emptied. The material that a float valve is constructed from must be suitable for the liquid in which it operates, which may be corrosive or at an extreme temperature. Float valves are used to automatically regulate the level of liquid within tanks
