Double Ball Isolation Valve | 8070P Series | EzPress Connections
Red-White Valve’s 8070P Isolation Drain Valve combines double-ball security with fast, solder-free EzPress connections for safe and efficient hydronic service.
Engineered for HVAC, process cooling, and commercial loop maintenance, this dual-ball valve design isolates drain ports mid-line—allowing section-by-section servicing without full system depressurization.
Built with a DZR lead-free brass body and chrome-plated full-port balls, it delivers 250 PSI WOG (Water, Oil, Gas) pressure handling and years of dependable, leak-free operation.
Key Features & Benefits
-
Double-Ball Isolation — Independent dual valves prevent crossflow and pressure loss during maintenance or system purging.
-
High-Flow Drain Port — ¾″ NH outlet with cap and chain purges large hydronic loops 50% faster than standard valves.
-
EzPress Connections — Quick, solder-free installation reduces downtime—ideal for retrofits and tight mechanical rooms.
-
Full-Port Chrome-Plated Balls — Maximize flow efficiency and eliminate internal restrictions.
-
DZR Lead-Free Brass Body — ASTM B927 C27453 brass ensures corrosion resistance and NSF potable-water compliance.
-
PTFE Seats & Adjustable Packing Gland — Maintain leak-free performance through 10,000+ operating cycles.
-
Temperature Range — Operates reliably from 15°F to 260°F (-9°C to 127°C) with antifreeze or anti-boil additives.
