  • Dual-Action System Optimization: Twin 0.75" purge ports enable simultaneous filling and draining, halving maintenance time in geothermal and high-rise HVAC systems.
  • Torch-Free Time Saver: EzPress connections install in seconds—bypass soldering for emergency retrofits in cramped mechanical rooms.
  • Municipal-Grade Toughness: Military chrome plating + DZR brass resist chlorine and brine, engineered for aggressive water treatment plants.
  • Extreme Climate Mastery: Operates from -9°C to 127°C (-9°C to 127°C) with antifreeze/anti-boil additives, ideal for Arctic geothermal or foundry cooling.

The 8020P Purge & Fill Valve revolutionizes closed-loop system maintenance with its twin high-flow purge ports and rugged EzPress connections. Designed for HVAC, industrial hydronics, and geothermal systems, this valve streamlines filling, draining, and pressure testing without system shutdowns. Built with a corrosion-resistant DZR lead-free brass body and a chrome-plated full-port ball, it delivers unmatched durability in high-pressure environments up to 250 PSI WOG (Water, Oil, Gas).

Key Features & Benefits

 Dual-Port Efficiency: Twin 0.75" hose drains enable simultaneous filling and draining, slashing maintenance time by 50% in industrial cooling loops and geothermal systems.
 EzPress Innovation: Solder-free connections install in seconds—ideal for retrofits or emergency repairs in tight mechanical spaces.
 Extreme-Temperature Resilience: Operates from 15°F to 260°F (-9°C to 127°C) with antifreeze (below freezing) or anti-boil additives (high-heat).
 Zero-Leak Assurance: Blow-out-proof stem and virgin PTFE seats ensure leak-free performance over 10,000+ cycles, even in corrosive media.
 Full-Port Dominance: Unrestricted flow design minimizes pressure drop during purging, critical for high-demand commercial systems.

Why the 8020P Stands Out

This valve isn’t just a tool—it’s a workflow revolution. The EzPress® fittings eliminate torch work, while the twin purge ports allow operators to fill and drain systems simultaneously, drastically reducing downtime. The DZR brass body and military-grade chrome plating resist pitting in chlorinated or brine environments, ensuring decades of reliable service.

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