PRODUCT REVIEW
“A PRV reduces the pressure to a required value, but what frequently causes confusion is the difference between dynamic and static pressure.”
WHICH PRV SHOULD I USE? There is a selection to choose from based on the application (cold water or hot and cold water service), with or without a pressure gauge, set using a screwdriver or a Dial up setting. When it comes to static control valves, the Caleffi PRESCAL 535 series of pressure reducing valves are a high quality WRAS approved example. This series of pressure reducing valves have the feature to be pre-adjustable. The pressure reducing valve can be set to the desired pressure value before installation, using an adjustment knob with a pressure setting indicator. After installation, the system pressure will automatically adjust itself to the set value. The internal cartridge containing all the regulating components is pre-assembled as a “self-contained unit”, to facilitate inspection and maintenance procedures.
