The 1.5-inch Wafer Check Valve from Kelor Valves is engineered to safeguard your pipeline system against reverse flow while occupying minimal space and weight. Crafted from corrosion-resistant stainless steel, its wafer-style design slips neatly between ANSI-flanged connections, making it ideal for applications where compactness and ease of installation are paramount.

Key Features & Benefits

• Slim, Space-Saving Profile: The wafer body is just 30–40 mm thick, reducing the need for long spool pieces and minimizing weight on elevated or mobile piping systems.
• Quick, Tool-Free Installation: Simply align the valve between matching flanges, insert studs or bolts, and tighten. No special gaskets—installation in minutes.
• Hydrodynamic Disc Design: The flap opens fully under forward flow, minimizing pressure drop; closes in under 0.1 seconds to prevent backflow.
• Durable Construction:
  • Body & Disc: AISI 304/316 stainless steel resists corrosion and scaling.
  • Seat: PTFE or NBR for tight shut-off and chemical compatibility.
  • Hinge Pin: Hardened stainless steel for long-term reliability.
• Low Maintenance: Fewer moving parts, easy in-line inspection and servicing.
