S100 / S1100
Full Port Stainless Steel
Single Chamber Basic Valve
The Watts ACV Models S100 and S1100 are full port, single
chamber basic valves that incorporate a one-piece disc and diaphragm assembly. This assembly is the only moving part within
the valve allowing it to open, close, or modulate as commanded
by the pilot control system.
The Stainless Steel design offers superior corrosion resistance,
as well as a lightweight alternative to conventional heavy iron
valves. Stainless Steel construction reduces corrosion, reducing
diaphragm wear and the frequency and labor costs associated
with traditional maintenance repairs.
