Function
Pressure reducing valves are devices which, when installed in 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 PresCal ™ Compact 533H series pressure reducing valve, ideal for small
system applications, is constructed of a DZR low-lead forged brass body and
incorporates a unique noise reducing and high flow seat design. It is easily
serviced with a replaceable cartridge and has an integral stainless steel
filter (35 mesh), helpful for water systems that may contain sediment or
debris. A tamper-resistant cap is included to replace the standard cap to hide
the adjustment screw to help prevent set point tampering.
The valve is ICC-ES certified to ASSE 1003, CSA B356, NSF/ANSI 61
(180°F/82°C Commercial Hot) , NSF/ANSI 372, low lead laws and listed by
ICC-ES. It meets codes IPC, IRC, NPC and UPC for use in accordance with
the US and Canadian plumbing codes.
