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

Npt Male Inlet × Npt Male Outlet	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.

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.

Polypropylene Float Valves

Able to withstand higher temperatures than PVC float valves, these valves have a temperature range of 35° to 175° F. Use them to control water levels in processing tanks and cooling towers. Valves have an unthreaded discharge outlet, which releases contents into a tank.
