Overview

Made from forged bronze, this check valve resists corrosion in water, seawater and mildly aggressive media while providing reliable automatic non-return protection. An internal disc lifts under forward flow and reseats on flow reversal to block backflow without operator input. Its bronze construction and compact threaded or flanged connections make it a natural fit for marine, plumbing, fire protection and water-service applications where corrosion resistance is essential.
