Double Ball Isolation Valve | 8070S Series | Solder Connections

Red-White Valve’s 8070S Double Ball Isolation Valve is purpose-built for high-pressure industrial hydronic and steam systems requiring absolute reliability. Its 600 PSI WOG (Water, Oil, Gas) rating and dual-ball isolation design allow safe mid-line servicing and drainage without shutting down the system. Constructed from DZR lead-free brass with chrome-plated full-port balls, this valve provides permanent, leak-free performance with ASME-compliant solder joints and maximum corrosion resistance.

Key Features & Benefits

  • 600# WOG Rating — Handles double the pressure of standard 300# brass valves for industrial-grade performance.
  • Dual-Ball Isolation Design — Enables simultaneous isolation and drainage for efficient system maintenance.
  • DZR Lead-Free Brass Body — ASTM B927 C27453 compliant and NSF certified for potable-water use.
  • High-Flow ¾″ NH Drain — Chain-secured cap prevents loss; EPDM gasket ensures tight sealing during service.
  • ASME Solder Connections — Permanent leak-free joints outperform threaded alternatives and resist vibration stress.
  • PTFE Seats + Blow-Out-Proof Stem — Delivers 20,000+ cycle life in high-pressure, corrosive environments.
  • Temperature Range — 15°F to 260°F (-9°C to 127°C) with antifreeze or anti-boil additives for extreme conditions.
