Product Description

Product Overview
Introducing the H71 Wafer Check Valve, a marvel of engineering that redefines compactness with its wafer connection design. Boasting an ultra-slim profile, it occupies merely 1/4 to 1/8 of the structural length of traditional flange check valves, shedding 75% to 95% of the weight. This revolutionary valve assures rapid closure, effectively minimizing water hammer phenomena. Its design minimizes fluid resistance, seamlessly integrating into both horizontal and vertical pipeline configurations. In stark contrast to the cumbersome H41 flange models, the H71 offers a streamlined solution, eliminating bulk and simplifying both installation and maintenance.

Structural Features
- Fast Closure: Experience the rapid response of our spring-loaded disc, achieving a swift short-stroke closure that markedly diminishes water hammer pressures even in high-velocity flow situations.
- Sealing Performance: The innovative single-disc structure, enhanced by spring-assisted sealing, guarantees a leak-proof operation with a remarkably prolonged service life, redefining reliability.
- Material Versatility: Tailor the valve to your needs with components available in carbon steel, robust stainless steel (304/316/316L), and durable duplex steel, ensuring compatibility across a wide spectrum of media.

Application Range
- Media Compatibility: Perfectly suited for diverse media such as water, steam, oil, and corrosive substances like nitric and acetic acid. With specialized materials, it confidently handles harsh, oxidative environments.
- Operating Parameters:
- Pressure Rating: Withstand pressures from PN10 to PN420 (Class150 to Class2500) with unwavering strength.
- Size Range: Accommodates a vast diameter range from DN15 to DN600, ensuring adaptability to extensive pipeline systems.
- Temperature Range: Engineered to operate from an extreme -196°C to 540°C, embodying versatility in varying thermal conditions.
- Industry Applications: A trusted choice across petrochemical, power generation, metallurgy, food processing, and more, it champions environmental protection and municipal pipeline networks.

Technical Standards
- Design & Manufacturing: Meticulously crafted in accordance with JB/T 8937 and API 594 standards, epitomizing excellence.
- Flange Connections: Excellently supports international standards like GB/T 9113 and ASME B16.5, ensuring global applicability.
- Testing & Certification: Rigorously tested to meet API 598 and GB/T 13927 protocols, with leading manufacturers accredited with ISO 9001, API 6D, ensuring unparalleled quality and reliability.

Installation & Maintenance
- Flow Direction: For optimal performance, align the flow with body arrow markings; suitable for both horizontal and vertical installations.
- Support Requirements: For larger valves, ensure independent support systems to maintain sealing integrity and prevent undue pipeline stress.

Performance Parameters
- Flow Resistance Coefficient: Notably decreases as diameter increases, exemplified by DN50 at 2.6 and DN1200 at 0.7, affirming superior efficiency.
- Flow Capacity: The DN100 valve showcases an impressive Kv=289 m³/h (Cv=338 as per US standards), signifying remarkable throughput capacity.

Material Configuration
- Standard Options:
- Body: Available in rugged WCB and premium 304/316 stainless steel, offering robustness and corrosion resistance.
- Disc & Spring: Crafted from high-grade stainless or alloy steel, ensuring enduring performance under varied conditions.
- Sealing Surface: Choose between reliable rubber or a durable hard-faced alloy overlay for superior sealing efficacy.

The H71 Wafer Check Valve exemplifies unparalleled efficiency, reliability, and adaptability, ideal for industrial pipeline systems. Prioritize media characteristics, pressure/temperature parameters, and installation environments for optimal selection. Consult manufacturer datasheets or technical experts for tailored specifications to maximize your project's success.
