This Kerick SR12 stainless steel rod is 1/4" in diameter and 12" long. It is made of 18-8 stainless steel for resistance to corrosion and has 1/4"-20 male threads on each end. It is intended for use with 1" inlet float valves and 6" or 8" float balls (sold separately). As part of a float valve installation, it is suitable for use in a variety of applications, such as fountains, livestock water tanks, and chemical manufacturing plants.

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 in a variety of applications, such as fountains, livestock water tanks, cooling towers, and chemical manufacturing plants.

Kerick Valve manufactures fluid level control valves for industrial applications. The company, founded in 1994, is headquartered in Jacksonville, FL.
