Submittal Sheet

Typical Specification
Furnish and install on the plans and described herein, a Caleffi 535HA
series pressure reducing valve as manufactured by Caleffi. Each valve must
be designed with a pressure balanced seat and self-contained removable
cartridge. The valve design must include a DZR low-lead forged brass
body, glass reinforced nylon cover, stainless steel filter, EPDM membrane
diaphragm and sealing gaskets, with PTFE compensating piston rings.
Equipped with operating knob with downstream pressure adjustment scale
for manual setting and tamper-proof adjustment locking screw. The valve
must be ICC-ES certified to ASSE 1003, CSA B356, NSF 61, NSF 372, low
lead laws and listed by ICC-ES; and meet codes IPC, IRC and UPC for use
in accordance with the US and Canadian plumbing codes. Each valve shall
be Caleffi model 535HA series or approved equal. (See product instructions
for specific installation information.)
CALEFFI
Application
Pressure reducing valves are devices which, when installed on water
systems, reduce and stabilize the pressure of the water entering from
the water supply main. This pressure, in general, is too high and
variable for domestic systems to operate correctly. The 535HA series
pressure reducing valves feature a dial indicator with direct readout allowing
easy pressure pre-adjustment. The valve is constructed of DZR low-lead
forged brass and incorporates a unique noise reducing and high flow seat
design, easy inline servicing with a replaceable cartridge and an integral
stainless steel filter (35 mesh), suitable for water systems that may contain
sediment and debris.
