Global functionality is one of Stiefel’s 220V valve's defining features. Each valve comes with custom dual voltage coils 220/240V with automatic voltage detection. Coils encased in epoxy resist moisture for outdoor boiler installations such as the steam system in a South East Asian rice mill where our valves functioned impeccably during the monsoon season. The M20x1.5 electrical connections are nickel plated brass which enhances resistance to corrosion while still allowing the elements of a humid climate.
