8020S Purge & Fill Valve

The 8020S Purge & Fill Valve redefines efficiency and durability in high-stakes environments. Designed for industrial hydronics, power plants, and large-scale HVAC systems, this valve combines a 600 PSI WOG (Water, Oil, Gas) rating with precision solder connections for permanent, leak-free performance. Its corrosion-resistant DZR lead-free brass body and chrome-plated full-port ball ensure flawless operation in the most aggressive media, from steam to chemical-laden fluids.

Key Features & Benefits

• Extreme-Pressure Mastery: 600# WOG rating—the highest in its class—handles refinery cooling loops, boiler systems, and high-pressure hydronics.
• Twin High-Flow Purge Ports: Dual 0.75" hose drains enable simultaneous filling and draining, slashing maintenance time by 60% in critical systems.
• Soldered Permanence: ASME-compliant solder joints deliver unmatched durability in high-vibration or seismic zones, outperforming press-fit alternatives.
• Arctic-to-Inferno Resilience: Operates from 15°F to 260°F (-9°C to 127°C) with antifreeze or anti-boil additives, ideal for cryogenic or superheated applications.
• Zero-Leak Assurance: Blow-out-proof stem and virgin PTFE seats withstand 20,000+ cycles, even in abrasive or corrosive environments.

Why the 8020S Dominates

This valve isn’t just a tool—it’s a lifeline for systems where failure is catastrophic. The military-grade chrome plating resists scaling in superheated steam, while the solder joints ensure decades of reliability in environments where press-fit systems falter. Designed for engineers who prioritize permanence over convenience, it’s the gold standard for mission-critical infrastructure.

Note: Requires ASME B16.18-compliant soldering practices. Pressure-test all joints post-installation.
