Reduced Port Stainless Steel
Single Chamber Basic Valve with
Mechanical Check Feature
The Watts ACV Models S6400 and S61400 are reduced port,
single chamber basic valves that incorporate a two-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 lower portion of
this two-piece assembly is a mechanical check feature, which
acts independent of diaphragm position or pilot control system,
and provides immediate check action when flow ceases. The
reduced port design offers improved low-flow performance as
compared to a full port valve in the same service.
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.
