The Flomatic Model C000/CA000 Main Valve is a self contained hydraulically operated, single diaphragmactuated globe or angled body valve with no pilot controls. The valve has three major components: the
body with a removable seat, the cover with bushing, and the diaphragm assembly. The diaphragm
assembly is the only moving part. The cover forms a sealed chamber above the diaphragm to separate
operating pressure from line pressure. Long service life and dependable operation are ensured due to
packless construction. The valve is designed for use with various types of pressure and/or electric
controls to provide the desired control of pressure or flow for a variety of water system applications. The
Flomatic Model C000/CA000 is the basic valve used for all Flomatic full port automatic control valves.
Principal of Operation
Full Flow Tight Closure
Full flow is achieved by releasing control
pressure from the cover chamber to a
lower pressure zone which allows line
pressure to open the diphragm assembly.
Tight closure is achieved by applying inlet
pressure to the cover chamber to leverage
the differential force of the larger
hragm surface area against the smaller
dia
seat area.
Modulating control is achieved by utilizing
a pressure regulating control valve to
automatically compensate for line pressure
fluctuations.
