Stainless Steel Series Basic Valves
ES-ACV-S6500-S61500
S6500 / S61500
Reduced Port Stainless Steel
Dual Chamber Basic Valve
The Watts ACV Models S6500 and S61500 are reduced port,
dual 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 or close as commanded by
the pilot control system.
When pressure is applied to the upper diaphragm chamber and
released from the lower diaphragm chamber, the valve travels
to a closed position. When pressure is applied to the lower
diaphragm chamber and released from the upper diaphragm
chamber the valve travels to a full open position. When pressure
is balanced between the upper and lower diaphragm chambers,
the valve will hold an intermediate position until commanded to
modulate open or closed 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.
