H71 Wafer Type Stainless Steel Check Valve

Core Structure: The H71 Wafer Type Stainless Steel Check Valve

1.consists of stainless steel valve body, rising stainless steel disc, corrosion-resistant return spring, bonnet and other components. Without external driving devices, it features a compact and lightweight structure.

Working Principle: When the medium flows forward through the H71 Wafer Type Stainless Steel Check Valve, the pressure pushes the disc to compress the spring and rise, opening the valve for unobstructed medium passage; when the medium flows backward, the spring force pushes the disc to reset quickly, which fits tightly with the seat sealing surface to block medium backflow and effectively reduce the damage of water hammer impact to the pipeline.

2.Superior Corrosion Resistance: The 304/316 H71 Wafer Type Stainless Steel Check Valve can resist erosion from corrosive media such as weak acid, weak alkali and salt spray, adapting to special working conditions in chemical industry, marine engineering, food and pharmaceutical industry, with a service life far longer than that of carbon steel check valves.

About Us

1.Our high-quality and durable H71 Wafer Type Stainless Steel Check Valve are manufactured via stainless steel precision casting + CNC finish machining. The disc sealing surfaces are precision-ground, ensuring sensitive opening and closing, reliable sealing and excellent corrosion resistance.

2.As an exporter, DIYE VALVE has strict requirements for the delivery of H71 Wafer Type Stainless Steel Check Valve. All products are wrapped with anti-rust film and packed in moisture-proof wooden cases, which are suitable for international logistics and transportation. This effectively prevents collision and rust during transportation and ensures the intact delivery of products.

Q:What are the core advantages of stainless steel wafer check valve compared with flange and lug types?

A: The stainless steel wafer check valve features a compact, lightweight wafer design—no flanges on the valve body, which saves installation space and reduces weight by 40% compared with flange types. It is clamped directly between pipeline flanges, simplifying installation and lowering costs. Combined with 304/316L corrosion resistance, it is ideal for narrow spaces, large-diameter pipelines and corrosive media scenes such as water treatment and chemical industry. Compared with lug types, it has higher cost performance for general on-off anti-backflow needs.
