Product Overview
Introducing the H71 Wafer Check Valve, a marvel of modern engineering that is designed with a sleek and compact wafer connection design. This innovation drastically reduces the structural length to merely 1/4 to 1/8 of conventional flange check valves, providing substantial savings in both size and weight. Imagine a valve that weighs just 1/4 to 1/20 of traditional models, offering unparalleled efficiency. Its rapid closure feature is meticulously crafted to drastically reduce the impact of water hammer, ensuring your systems run smoothly. Additionally, it boasts low fluid resistance and is effortlessly adaptable to both horizontal and vertical pipelines. The H71 type triumphs over the H41 flange check valves, eliminating issues of bulkiness and simplifying installation and maintenance, setting a new standard for user-friendly design.
Structural Features
- Fast Closure: The ingenious spring-loaded disc design ensures a swift and brief stroke closure, significantly diminishing water hammer pressure, especially during high-flow conditions. Experience efficiency like never before.
- Sealing Performance: With a single-disc vertical movement coupled with spring-assisted sealing, the check valve guarantees absolute zero leakage and promises an extended, trouble-free service life.
- Material Versatility: The components are crafted in a range of materials like carbon steel, stainless steel (304/316/316L), and duplex steel. This versatility allows adaptation to a wide array of media demands, offering a bespoke solution for every need.
Application Range
- Media Compatibility: This valve is your versatile ally, proving compatible across a spectrum of media such as water, steam, oil, nitric and acetic acid, strongly oxidative media, and urea. Its material selection extends its ability to thrive even in corrosive environments, ensuring resilience and performance.
- Operating Parameters:
- Pressure Rating: Expertly designed for a pressure range from PN10 to PN420 (Class150-Class2500), making it ideal for various industrial applications.
- Size Range: Available in sizes ranging from DN15 to DN600, meeting diverse operational requirements with precision and flexibility.
- Temperature Range: Capable of withstanding extreme temperatures from -196°C to 540°C, ensuring reliability in the most demanding conditions.
