不锈钢对夹式止回阀

Type：H71W，H77X

Subtitle：Corrosion-Resistant Wafer Check Valve

The Stainless Steel Wafer Check Valve is a corrosion-resistant, non-return valve designed to prevent reverse flow in demanding environments such as chemical processing, marine applications, and high-purity systems. Featuring a wafer-style design, this valve is installed between flanges, offering a compact, lightweight solution with minimal pressure drop. Constructed entirely from stainless steel (ASTM A351 CF8M/CF3M), this valve excels in handling corrosive media, high temperatures, and high-pressure conditions. Its swing disc or dual disc design ensures rapid sealing upon flow reversal, making it ideal for applications requiring reliability and durability.

产品概览	The Stainless Steel Wafer Check Valve is a corrosion-resistant, non-return valve designed to prevent reverse flow in demanding environments such as chemical processing, marine applications, and high-purity systems. Featuring a wafer-style design, this valve is installed between flanges, offering a compact, lightweight solution with minimal pressure drop. Constructed entirely from stainless steel (ASTM A351 CF8M/CF3M), this valve excels in handling corrosive media, high temperatures, and high-pressure conditions. Its swing disc or dual disc design ensures rapid sealing upon flow reversal, making it ideal for applications requiring reliability and durability.

主要功能	Full Stainless Steel Construction:Body, disc, and fasteners made of CF8M (316 stainless steel) or CF3M (316L stainless steel).Resists pitting, crevice corrosion, and oxidation in aggressive media (e.g., chlorides, acids). Wafer Design:Compact and lightweight, ideal for space-constrained installations.Installed between ANSI/DIN/JIS flanges without additional bolts or gaskets. Low Resistance & Rapid Closure:Optimized flow path minimizes pressure drop.Swing disc or spring-assisted dual disc ensures immediate sealing to prevent water hammer. High-Temperature Capability:Operates reliably in temperatures up to 400°F (204°C), with optional materials for higher temperatures. 遵守规定：Meets API 594, ASME B16.34, ISO 17292, and NACE MR0175 standards.

运行优势	Corrosion Resistance: Ideal for harsh environments, including marine and chemical exposure. 卫生设计 Electropolished surfaces (Ra ≤ 0.8 μm) meet FDA and EHEDG standards for sanitary applications. Low Maintenance: Self-cleaning design reduces fouling and extends service life. 多功能性： Suitable for both high-purity and industrial corrosive media.

为什么选择我们	Material Integrity: Full stainless steel construction ensures longevity in aggressive environments. Fast Delivery: Standard DN50-DN300 sizes in stock with global logistics support. Customization: Optional coatings (PTFE, DLC), high-temp springs, or specialty seals. Certifications: 3.1 Material Certificates, NACE compliance for sour service.
