Transfer Valve

National Filtration Systems transfer / diverter valves are manufactured to exacting standard by Hydraulic Company of America.  Featuring all fabricated steel construction, these valves provide unequaled performance in a wide range of fluid flow applications.

The positive mechanical lockdown of the patented shoe seal assures zero leakage to the inactive side of the flowing system.  The sealing mechanism delivers zero frictional drag on the valve change-over while maintaining uninterrupted flow with very low pressure drop.  The center body “lip” ring seal assures no leakage of contaminated fluid to the clean side of the valve for filtration applications.

The rugged construction with welded machine steel body (internally plated) and stainless steel shoe / linkage mechanism assures a long trouble free service life.  The efficient design also allows for field replacement of any component with standard hand tools.  The standard valve series is also available in a 3-way valve design and a split 3-way for cooler applications.  All with the same patented seal system.
