Product Overview
Introducing the H71 Wafer Check Valve, a revolutionary advancement in valve technology, crafted with a compact wafer connection design that showcases an ultramodern approach to reducing structural length to just 1/4 to 1/8 of conventional flange check valves. This innovation not only minimizes size but also dramatically lowers weight to between 1/4 to 1/20 of traditional valves. The pinnacle of its design lies in its rapid closure capabilities, effectively mitigating water hammer effects, while ensuring minimal fluid resistance. Its universal adaptability to both horizontal and vertical pipelines makes it an unparalleled choice over the bulkier H41 flange check valves, which often present challenges in installation and maintenance.
Structural Features
- Unmatched Speed in Closure: Featuring a state-of-the-art spring-loaded disc that enables a swift, short-stroke closure, this valve is engineered to significantly decrease water hammer pressure even in the most demanding high-flow conditions.
- Superior Sealing Technology: Utilizing a single-disc vertical movement with spring-assisted sealing, this design guarantees zero leakage and extends the operational life far beyond traditional expectations.
- Versatile Material Configuration: Designed with flexibility in mind, components such as the body and disc are available in a variety of materials including carbon steel, stainless steel (304/316/316L), and duplex steel, accommodating a wide spectrum of media requirements with ease.
Application Range
- Extensive Media Compatibility: Crafted to handle a diverse range of media including water, steam, oil, nitric acid, acetic acid, strongly oxidative environments, and urea, its material selection ensures robust functionality even in corrosive environments.
- Operating Parameters:
- Pressure Rating: Specifically engineered to accommodate a wide pressure range from PN10-PN420 (Class150-Class2500), ensuring suitability for varying system demands.
- Size Range: Accommodates a diversity of applications with sizes ranging from DN15 to DN600.
- Temperature Range: Engineered for extreme conditions, withstanding temperatures from -196°C to 540°C.
- Broad Industry Applications: This versatile valve finds its application across numerous industries including petrochemical, power generation, metallurgy, food processing, environmental protection, and municipal pipeline systems.
Technical Standards
- Rigorous Design & Manufacturing Standards: Built to conform with top-tier standards such as JB/T 8937 and API 594, ensuring excellence in manufacturing and design.
