The 8020E Purge & Fill Valve redefines closed-loop system servicing with its twin high-flow purge ports and rugged PEX F1960 connections. Designed for HVAC, industrial hydronics, and geothermal systems, this valve streamlines filling, draining, and pressure testing without system shutdowns. Its corrosion-resistant DZR lead-free brass body and chrome-plated full-port ball withstand extreme pressures up to 400 PSI WOG (Water, Oil, Gas), making it the go-to choice for demanding environments.
Key Features & Benefits
✅ Twin-Port Power: Dual 0.75\\” hose drains enable simultaneous filling and draining, cutting maintenance time by 50%.
✅ Extreme-Pressure Ready: 400# WOG rating outperforms standard valves in refinery cooling loops and high-rise HVAC.
✅ Torque-Free Installation: PEX F1960 press connections eliminate soldering—secure leaks in seconds, even in tight spaces.
✅ Arctic-to-Boiler Resilience: Operates from 15°F to 260°F (-9°C to 127°C) with antifreeze or anti-boil additives.
✅ Decades-Long Seal Integrity: Blow-out-proof stem and virgin PTFE seats endure 10,000+ cycles without leakage.
