This stainless steel dual plate wafer check valve is a high-efficiency automatic valve designed to prevent reverse fluid flow. Made of premium 304/316/316L stainless steel, it offers exceptional corrosion resistance and structural durability for harsh industrial environments. The dual plate design ensures quick response, low pressure loss, and tight sealing, while the wafer type allows space-saving, easy installation between flanges. No external power is required—it operates via fluid pressure, reducing maintenance costs significantly.
