Flomatic 4501SSX 1″ Stainless Steel Auto-Drain Valve 5 PSI – Model 70 | Pump Professionals

Description

The Flomatic 4501SSX is a 1″ stainless steel automatic drain valve from Flomatic’s Model 70 series, engineered to protect piping systems from freeze damage, water hammer, and residual pressure buildup. Built for reliability in outdoor and exposed installations, this valve automatically opens when system pressure drops, draining standing water from lines without any manual intervention.

As part of the trusted Flomatic Model 70 lineup, the 4501SSX functions as a true automatic drain back valve SS, using a simple pressure-actuated mechanism that opens at 5 PSI to release trapped water from the line once the pump shuts off. The auto-drain valve, with 1-inch stainless-steel construction, ensures long-term corrosion resistance in harsh outdoor environments where less durable materials would deteriorate quickly. This 5 PSI drain valve design requires no electrical components, timers, or manual operation — the valve responds directly to system pressure, making it a dependable set-and-forget solution. For pump system operators in cold climates, the freeze-protection valve pump capability is a critical feature, eliminating the need for manual draining or costly heat-tape installations. Its 1″ threaded connections integrate seamlessly into standard discharge piping configurations.

The Flomatic 4501SSX is well-suited for pump discharge lines, irrigation mainlines, sprinkler systems, and any above-ground piping exposed to freezing temperatures. It is equally effective in drip irrigation systems, booster pump installations, and seasonal water supply lines where complete drainage between cycles is essential. Contractors and irrigation system designers working in cold-weather regions will find this valve an indispensable component for protecting infrastructure and reducing winterization labor costs season after season.
