Ratio Pressure Reducing Valves

Ratio pressure reducing valves provide a stable, fixed ratio between upstream and downstream pressure — typically 2:1 or 3:1 — without external power or pilot adjustment. AFC Valves EU supplies hydraulically operated ratio PRVs for trunk-main pressure management, district metered area inlets, and high-rise building feeders. Sizes DN50 to DN400, configurable with optional check function. Stable downstream pressure under varying upstream conditions reduces leakage and pipe-burst risk on aged networks.
