Product Overview
Introducing the H71 Wafer Check Valve, a true marvel of engineering excellence! Experience cutting-edge innovation with its advanced wafer connection design, which remarkably compresses structural length to a mere 1/4 to 1/8 of conventional flange check valves. lightening the load to just 1/4 to 1/20 of traditional designs. Revel in its rapid closure capability that powerfully minimizes water hammer risks, while also offering ultra-low fluid resistance. Designed for effortless fitting in both horizontal and vertical pipelines, the H71 overcomes the bulky nature and upkeep demands of traditional H41 flange check valves. Elevate your pipeline operations with the modern efficacy of the H71 solution.
Structural Features
- Experience lightning-fast responsiveness with the Fast Closure feature. The spring-loaded disc facilitates rapid, short-stroke closure, significantly mitigating water hammer pressure, even amid high-flow conditions.
- Our Sealing Performance is second to none. The innovative single-disc, coupled with a spring-assisted mechanism, ensures a perfect seal, guaranteeing zero leakage and an impressively extended service life.
- Enjoy Material Versatility with customizable options in carbon steel, stainless steel (304/316/316L), and duplex steel. Tailor components like the body and disc to seamlessly meet a diverse range of media requirements.
Application Range
- Media Compatibility: Versatile and robust, this valve is your solution for a wide array of media including water, steam, oil, nitric acid, acetic acid, highly oxidative environments, and even urea, thanks to materials that withstand the harshest, most corrosive conditions.
- Operating Parameters:
- Pressure Rating: Engineered for durability, offering a formidable PN10-PN420 (Class150-Class2500) range.
- Size Range: Catering to all needs with versatile sizes from DN15-DN600, ensuring a perfect fit for any application.
- Temperature Range: Unmatched adaptability from an icy -196°C to a blazing 540°C, covering every extreme.
- Industry Applications: Proudly enhancing operations in diverse sectors such as petrochemical, power generation, metallurgy, food processing, environmental protection, and municipal pipeline systems with unparalleled excellence.
