ES-ACV-M6400-M61400
M6400 / M61400
Reduced Port Ductile Iron Single
Chamber Basic Valve with
Mechanical Check Feature
The Watts ACV Models M6400 and M61400 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.
