Twin Purge Ball Valve | 8020P Series | EzPress × EzPress w/ Dual Drains
Red-White Valve’s 8020P Twin Purge & Fill Valve delivers precision control and time-saving functionality for high-performance hydronic, geothermal, and industrial cooling systems.
Featuring dual ¾″ hose drains and EzPress press-fit ends, this valve enables simultaneous filling, purging, and testing without shutting down the system.
Constructed from DZR lead-free brass with a chrome-plated full-port ball, it withstands pressures up to 250 PSI WOG (Water, Oil, Gas) and ensures corrosion resistance, leak-free service, and efficient system maintenance.
