All standard Bob^® Brass Float Valve Assemblies consist of brass valve, brass stem, and copper float ball. The stem and float ball listed are the recommended minimum size for positive water level control . Of course other combinations may also work or be necessary depending on your inlet pressure.

Chances are, we already offer the valve or assembly you are looking for, HOWEVER, custom assemblies, heavier/longer stems, other float balls, etc. are available! Special valve designs and/or assemblies can be engineered, manufactured, and tested to your specifications!

For special assemblies, list parts separately, i.e. valve, stem, and float ball.

For High Temp or Hydrocarbon Fluid (oil) applications, add suffix "V" to the part number for DISC and/or CUP made of Viton®. R900 & R600 standard with CUP made of Teflon®.

For polypropylene float add suffix "P" to the assembly number.
