  • Mid-Line Safety Lock: Dual-ball valve design enables safe isolation during active system maintenance—no full shutdowns required for cooling towers or HVAC glycol loops.
  • Hazard-Zone Ready: EzPress connections install solder-free in 30 seconds, eliminating hot work permits in chemical plants or food processing facilities.
  • CIP System Optimized: NSF/ANSI 61-certified for potable water, ideal for rapid sanitization cycles in breweries and dairy plants.
  • Emergency Drain Power: 0.75" high-flow port evacuates 500+ gallon systems 50% faster during municipal water treatment crises.

The 8070P Isolation Drain Valve combines industrial-grade durability with revolutionary maintenance efficiency. Designed for HVAC, industrial process loops, and commercial hydronics, this valve features a double ball valve design for failsafe isolation, enabling safe system servicing without full shutdowns. With a corrosion-resistant DZR lead-free brass body and 250 PSI WOG (Water, Oil, Gas) rating, it delivers unmatched reliability in aggressive media like glycol, steam, or brine.

Key Features & Benefits

  • Dual-Ball Isolation Security: Twin chrome-plated ball valves isolate drain ports mid-system, preventing accidental depressurization during maintenance.
  • EzPress Speed: Solder-free connections install in 30 seconds—ideal for emergency repairs or retrofits in cramped mechanical rooms.
  • High-Flow Drain Dominance: 0.75" hose port with cap/chain purges 500+ gallon systems 50% faster than standard drains.
  • Arctic-to-Boiler Toughness: Operates from 15°F to 260°F (-9°C to 127°C) with antifreeze/anti-boil additives for cryogenic or high-heat plants.
  • Zero-Leak Assurance: Blow-out-proof stem and virgin PTFE seats endure 10,000+ cycles, even in corrosive or high-vibration environments.

Why the 8070P Excels

This isn’t just a drain valve—it’s a system guardian. The double-ball design acts as a mechanical safety lock, while the EzPress fittings eliminate torch work in hazardous areas. Military-grade chrome plating resists pitting in chlorinated water, and the full-port design ensures zero pressure drop during high-volume purges.

Note: Pair with EzPress-compatible tools (sold separately) for code-compliant installations.
