Npt Female Inlet × Discharge Outlet	Npt Female Inlet × Npt Female Outlet	Npt Male Inlet × Npt Male Outlet

With Bobbing Polypropylene Float	With Bobbing Copper Float

Control water levels in processing tanks and cooling towers.

Bobbing Float—Use valves with bobbing float in tanks where the float may get jostled. The float moves independently of the rod, so valve operation is not disrupted.

Discharge—Valves with a discharge outlet release contents into your tank; the outlet is unthreaded.

Extra-Compact Plastic Float Valves

Control the water level in spaces where a rod and lever won’t fit; these float valves have an internal float and connect to your pipe. When the water level reaches the bottom of the valve, the float rises to stop the flow. The discharge outlet is unthreaded and releases contents into your tank.

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.

	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.

Bronze Float Valves

With a durable bronze body, these float valves can be used with water and hydraulic fluid. Use them to control liquid levels in processing tanks and cooling towers. They have a 360° rotating joint that allows you to alter the angle between the valve body and rod to fit in your tank.
