Stainless Steel Wafer Type Swing Check Valve

Stainless Steel Swing Check Valve – Wafer Type (A Range)

The Stainless Steel Wafer Swing Check Valve offers a compact, efficient, and corrosion-resistant solution for preventing backflow in pipelines. Designed to operate automatically with line pressure, this non-return valve is constructed from durable 304 stainless steel, making it ideal for aggressive or corrosive media in processing, water treatment, and industrial applications.

Its wafer-style body ensures easy installation between flanges without the need for extensive pipework modification, and its EPDM soft seat provides excellent sealing with minimal cracking pressure—ensuring low resistance to flow while reliably stopping reverse flow.
