A dual plate wafer check valve is a highly efficient non-return device that uses two spring-assisted semicircular plates to prevent backflow. Compared to traditional swing check valves, its compact wafer design saves significant installation space and weight, while the rapid spring closure minimizes water hammer and protects upstream equipment.
This 16-inch model is specifically engineered for demanding applications requiring high corrosion resistance and high-temperature capability. It features a fully stainless steel construction: a CF8M (AISI 316) body and disc, a CF8M/SS316 metal seat, and an SS316 stem. Because it uses a metal-to-metal hard seal rather than a rubber elastomer, this valve is highly resistant to aggressive chemicals, high temperatures, and abrasive media.
As a direct OEM/ODM manufacturer with over 15 years of export experience, Tianjin Worlds Valve Co., Ltd. builds valves to your exact specifications. Our facility is ISO 9001:2015 certified by LRQA, and our pressure equipment holds CE/PED (Module H) and UKCA certifications.

1. Fully Metal Seated (Hard Seated) Design
High-Temperature Capability–Unlike soft-seated valves (EPDM/NBR), the SS316 metal-to-metal seal is not limited by rubber degradation. It is suitable for high-temperature steam, hot oil, and thermal fluids.
Superior Wear Resistance–The metal seat withstands abrasive media, slurries, and high-velocity flow without tearing or swelling.
Long Service Life–The hard-faced sealing surfaces maintain their integrity over hundreds of thousands of cycles, reducing maintenance frequency.
2. 100% Stainless Steel Construction (CF8M)
Ultimate Corrosion Resistance–Both the body, disc, and seat are made from CF8M (cast 316) or SS316, providing excellent resistance to chlorides, seawater, and highly corrosive chemicals.
Hygienic & Non-Toxic–The all-metal wetted parts make it suitable for high-purity applications, avoiding the extractables often found in rubber seats.
3. Spring-Assisted Rapid Closure
Protection Against Water Hammer–The stainless steel torsion springs close the dual plates rapidly upon flow reversal, preventing damaging pressure surges before they can travel back to the pump.
Low Pressure Drop–When fully open, the streamlined dual-plate design offers minimal flow resistance, reducing energy consumption.
Any Orientation–The spring-assisted mechanism allows for horizontal, vertical, or angled installation without relying on gravity.
Industry | Application |
Chemical & Petrochemical | Handling aggressive acids, alkalis, and solvents where rubber seats would degrade |
Power Generation | High-temperature cooling water, condenser systems, and steam lines |
Desalination & Seawater | Brine transfer and seawater intake (CF8M resists chloride pitting) |
High-Purity Processing | Pharmaceuticals and fine chemicals where zero contamination is critical |
Oil & Gas | Refining and process lines with elevated temperatures |
