Flow Switch V121F Series

For high flow switching applications up to 20 GPM, this design offers the same proven advantages of the V121F series but features larger fittings for reduced pressure drop. The nonmagnetic switching principle produces resistance to both dirty media and external electromagnetic equipment. The inline design is easily integrated into most plumbing layouts.
