PIETRO FIORENTINIPILOT 204/A + R14/A REFLUX – SIZE:1/2 regulator & kits
½″ pilot loop combining 204/A (set‑point pilot) and R14/A (pre‑regulator) for REFLUX service. R14/A stabilizes feed to the 204/A so the main regulator maintains outlet pressure with high accuracy over varying inlet and flow. Kit includes diaphragms, seats, springs, filters and O‑rings for both devices.
