Floats for Chemicals

Made of polyethylene, these floats can be used with chemicals, salts, and caustic fluids.

Ball floats are self-tapping when used with a threaded rod.

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.

Valves with compression inlet connections are for small-scale applications using tubing.

Compact Metal Float Valves

Smaller than other float valves, these are sized for containers with limited space. Use them to control water levels in processing tanks and cooling towers.

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