Description
Description
The WATTS ACV Models S6100 and S61100 are reduced port, single chamber basic valves that incorporate a onepiece 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 reduced port design offers improved low-flow performance
and cavitation resistance.
The Stainless Steel design offers superior corrosion resistance, as well as a lightweight alternative to conventional
heavy iron valves. Stainless Steel construction provides extended diaphragm life, and reduces the frequency and labor
costs associated with traditional maintenance repairs.

Maximum continuous flow based on velocity of 20 ft. per second.
Maximum intermittent flow based on velocity of 25 ft. per second.
The CV factor of a valve is the flow rate in US GPM at 60° F that will cause a 1 psi drop in pressure.
The factors stated are based upon a fully open valve.
CV factor can be used in the following equations to determine Flow (Q) and Pressure Drop (r P):
Q (Flow) = CV r P rP (Pressure Drop) = (Q/CV)
