The 8070S Isolation Drain Valve sets the benchmark for critical system maintenance in high-pressure environments. Designed for power plants, refineries, and industrial hydronics, this valve combines a 600 PSI WOG (Water, Oil, Gas) rating with precision solder joints for unshakable reliability. Its double ball valve design enables safe isolation during active system servicing, while the DZR lead-free brass body and chrome-plated full-port ball thrive in aggressive media like steam, brine, or chemical-laden fluids.
Key Features & Benefits
- Dual-Ball Fail-Safe Design: Isolate drain ports mid-system without full shutdowns—critical for nuclear cooling loops or refinery steam lines.
- 600 PSI Brute Strength: Highest-in-class pressure rating for extreme industrial applications where standard valves falter.
- Soldered Permanence: ASME-compliant solder joints ensure leak-free integrity in high-vibration or seismic zones.
- Arctic-to-Inferno Resilience: Operates from 15°F to 260°F (-9°C to 127°C) with antifreeze/anti-boil additives.
- Zero Maintenance Leaks: Blow-out-proof stem and virgin PTFE seats endure 20,000+ cycles, even in abrasive fluids.
