The Adjustable Non-Return valve is an innovative solution
for fluids flow adjustment (style needle-valves) with a self-cleaning
mechanism and integral reliable ball-based non-return
valve.
Its major parts are made of PVC-U to easily fit all standard
Ø25 mm PVC glue socket fittings. It is especially designed to
fit on top of a Rotameter.
All ANR-1500 parts are chemical resist based on standard
material resistance tables of each part’s structure material.
