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.

Float Valve Bodies for Chemicals

Npt Female Inlet × Npt Female Outlet

Made of stainless steel, these float valves have excellent corrosion resistance even when exposed to chemicals. Combine them with floats and rods (not included) to create float valves that meet exact specifications.

Valve bodies with a PTFE seal withstand higher temperatures than valve bodies with a fluoroelastomer seal.
