Float Valve Bodies for Water

Combine these float valve bodies with floats and rods to create float valves that meet exact specifications. Made of brass, they resist corrosion from water. This makes them ideal for use in cooling towers, high-pressure washers, and processing tanks. However, if exposed to salt or chemicals, they’ll tarnish.

90° Elbow, NPT Male Inlet × NPT Male Outlet


	Smooth Rotating Plunger	Fluted Rotating Plunger

Valve bodies with an NPT outlet thread onto pipe to direct water to a specific location. They’re often used to send water to the bottom of a tank, limiting splashing and disruptions at the surface level.

Viton® Fluoroelastomer Seal—Valve bodies with a Viton® fluoroelastomer seal withstand higher temperatures than those with a Buna-N seal.

Fluted Plunger—Valve bodies with a fluted plunger keep contaminants from getting trapped between the plunger and valve body. This gives your valve stem a seamless path to actuate, extending the life of your valve. They’re ideal for sandy or silty applications, such as in livestock tanks.

Rotating Plunger—Valve bodies with a rotating plunger minimize wear on the internal seal. When the valve opens and closes, the plunger rotates freely. This means the internal seal wears evenly, extending the life of the valve body.

Float Valve Bodies for Drinking Water

Safe for use in drinking water systems, these float valve bodies meet NSF/ANSI 61 standards. Combine them with rods and floats to create custom float valves. They’re made of PVC, so they’re a lightweight alternative to metal valve bodies. With a nonrotating plunger, they maintain a tight seal even in turbulent water, such as in mixing tanks and tanks with boiling water.

Float Valve Bodies for Chemicals


	Round Rotating Plunger

Often found in tanks that are frequently washed down, these float valve bodies are 316 stainless steel, so they resist corroding from harsh cleaners. To create custom float valves, combine these valve bodies with floats and rods. Thread them onto pipe to direct water to a specific location. They’re frequently used to send water to the bottom of a tank to limit splashing and disruptions at the surface level. When the valve opens and closes, the plunger rotates freely. This means the internal seal wears evenly, extending the life of the valve body.

Teflon® PTFE Seal—Valve bodies with a Teflon® PTFE seal withstand higher temperatures than those with a Viton® fluoroelastomer seal.
