About this asset

Engineered for commercial MEP systems, this Revit family depicts a 957 Series reduced pressure backflow preventer with dual shutoff valves. The assembly incorporates a central cylindrical stainless-steel body flanked by two heavy-duty flanged gate valves finished in industrial red coating. Prominent top-mounted handwheels allow clear operational clearance verification, while an integrated differential pressure relief valve projects downward from the central section. Stainless-steel hydraulic sensing tubing connects the upstream zone to the relief module. Two adjustable metal support brackets cradle the lower pipe sections for structural floor anchoring. Four distinct test cocks with protective caps are positioned along the body for cross-connection control testing.

The download is a 645 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Designed for insertion into pipework networks within Autodesk Revit, this family aligns directly with domestic cold water or fire suppression supply lines. Connect MEP pipe elements directly to the flanged ends to maintain continuity in flow calculations and hydraulic system graphics. Visualisers and coordinators can run collision checks in technical rooms and verify clearance envelopes around the valve stems and downward discharge port.

Essential for commercial mechanical rooms, industrial plants, hospitals, and high-rise developments, this RPZ valve assembly safeguards potable water infrastructure against contamination from backpressure and backsiphonage. The component coordinates cleanly with water main risers, booster pump skids, water meter assemblies, and fire service lines during detailed design and construction documentation. MEP engineers and BIM technicians search for this model under backflow preventer, RPZ assembly, and flanged pipe accessory.
