Expansion Tank Ball Valve | 8080 Series | NPT | Full Port | DZR Lead-Free Brass | 600 PSI WOG

RWV 8080 Series Expansion Tank Ball Valves are engineered for dependable performance in high-pressure, closed-loop hydronic, boiler, and industrial cooling systems. Designed with a full-port ball and 600 PSI WOG rating, these valves allow fast, leak-free isolation of expansion tanks without system shutdown—simplifying maintenance while enhancing safety.

Constructed from DZR (Dezincification-Resistant) lead-free brass and certified to NSF/ANSI 61 & 372 and AB1953 standards, the 8080FT valve offers superior corrosion resistance and long service life in harsh environments. A built-in high-flow hose drain with a tethered cap ensures quick, controlled draining, while an adjustable packing gland provides long-term sealing integrity under thermal cycling and pressure variations.
