The Tri-Set pressure limiting valve gives you three selectable pressure settings in one compact valve — 350kPa, 500kPa or 600kPa — so a single SKU covers jobs that would otherwise need three different valves. Setting is adjusted with the supplied Allen key: turn clockwise for 600kPa, anti-clockwise for 350kPa, with a visual alignment mark to confirm the setting. Ships preset at 500kPa.
Built from dezincification-resistant DR brass with waterways engineered for strong flow characteristics, it suits vertical or horizontal installation and works well in enclosed spaces — cupboards, under sinks, and tight service risers. The no-vent-hole design means it can be installed in an approved in-ground box, though the valve itself must not be buried directly.
Ideal for limiting pressure to electric, solar, gas storage, and heat pump hot water systems, and general mains pressure limiting applications.
