Zero Leakage and Zero Frictional Drag
Transfer valves engineered for filtration, gas separation, and critical fluid systems — built for decades of trouble-free service.
Engineered for Filtration Service
Every design decision in a National Filtration Systems valve is made with one goal: keep clean streams clean.
Core Technology
Center-Body Lip Ring Seal
The valve's center-body lip ring seal ensures that contaminated fluid cannot migrate to the clean side — a critical requirement in filtration and separation service.
