Experience unmatched reliability and performance with our Stainless Steel Wafer Check Valve – 1 Inch, precision-engineered to safeguard your piping systems from backflow and contamination. Crafted from premium 316-grade stainless steel, this wafer-style valve combines rugged durability with compact design, making it the ideal choice for demanding industrial, commercial, and residential applications.

Key Features & Benefits

• Superior Corrosion Resistance: The 316 stainless steel body and disc ensure exceptional resistance to corrosion, pitting, and chemical attack, even in harsh environments such as seawater, chemical processing, and food-grade applications.

• Compact Wafer Design: Engineered to fit snugly between two flanges, the wafer configuration demands minimal face-to-face length and reduces installation footprint—perfect where space is at a premium.

• Smooth, Rapid Response: A streamlined disc and hinge mechanism guarantee instant closure when flow reversal occurs, preventing water hammer and protecting upstream equipment from damage.

• Low Pressure Drop: The wafer check valve’s streamlined internal profile minimizes flow resistance, ensuring efficient fluid transfer and energy savings over its service life.

• Versatile Sealing Options: Available with PTFE or EPDM seat inserts, the valve achieves bubble-tight sealing under a wide range of temperatures and pressures (up to PN16), accommodating liquids, gases, and steam.
