Typical Specification
Furnish and install on the plans and described herein, a Caleffi AutoFill™
pre-adjustable automatic combination filling valve and backflow preventer as
manufactured by Caleffi. Each valve must be designed with a visual system
pressure setting indicator. The filling valve design must include a brass
body, nylon plastic cover, sliding surfaces in anti-scale plastic, diaphram
and seals in NBR and removable cartridge for maintenance operations. The
filling valve must have a pressure indicator for pre-adjustment of device,
accuracy ±2 psi (±0.15 bar). Complete with isolating valve and filter. The
dual check continuous pressure backflow preventer with atmospheric vent
must be certified to CSA B64.3 and ASSE 1012, constructed of brass body,
stainless steel filter, 35 mesh (0.474 mm), check valve in PSU, diaphragm
and seals in EPDM. Integral downstream pressure gauge (0-60 psi/0-4 bar)
for codes 573012A and 573019A. (See product instructions for specific
installation information.)
CALEFFI
Application
The automatic filling valve is a device consisting of a pressure reducing
valve with compensating seat, visual system pressure setting indicator,
an inlet filter, anti-scale internal parts, a shut-off valve (round knob
on bottom) and a check valve. It is installed on the water inlet piping
in sealed heating systems, and its main function is to maintain the
pressure of the system at a set value, automatically filling up with
water as required. The valve is pre-adjustable, meaning it can be
set to the desired pressure value before the system charging phase.
After installation, during the filling or topping-off phase, the water
feed will stop when the set pressure is reached. This valve fills 50%
faster than other valves. There are no levers to flip or valve to close.
Pre-assembled with the 573 series backflow preventer, the AutoFill
™
Combo features an atmospheric vent which is designed to protect
drinking water systems from return flow, caused by back-siphoning
or back pressure, of contaminated fluids. The 573 series has been
specifically certified to standards CSA B64.3 and ASSE 1012.
