Product Overview
Introducing the meticulously engineered H71 Wafer Check Valve, a marvel of compact design with an innovative wafer connection. Its structural length is a mere fraction (1/4 to 1/8) of traditional flange check valves, shedding the typical bulk and reducing weight dramatically (down to 1/20 of conventional designs). This valve not only ensures rapid closure for effective water hammer mitigation but also provides minimal fluid resistance, making it a versatile choice for both horizontal and vertical pipeline integrations. It addresses and rectifies the size and maintenance challenges found in the H41 flange check valves, offering a streamlined solution for modern industrial needs.
Structural Features
- Fast Closure: Engineered with a spring-loaded disc, ensuring swift and efficient short-stroke closure. This feature significantly diminishes water hammer pressure, even in high-flow environments.
- Sealing Performance: The single-disc mechanism moves vertically with spring assistance, guaranteeing impeccable sealing with zero leakage, thereby prolonging the valve's service life phenomenally.
- Material Versatility: Constructed with a range of materials including carbon steel, stainless steel (304/316/316L), and duplex steel, making it adaptable to diverse media requirements across industries.
Application Range
- Media Compatibility: Versatile across various media such as water, steam, oil, nitric acid, acetic acid, strongly oxidative substances, and urea. The thoughtful material selection extends its compatibility to corrosive environments as well.
- Operating Parameters:
- Pressure Rating: Withstands pressures from PN10 to PN420 (Class150-Class2500), accommodating a wide range of industrial applications.
- Size Range: Available in sizes ranging from DN15 to DN600, offering flexibility for different system requirements.
- Temperature Range: Operates efficiently in extreme temperatures from -196°C to 540°C, ensuring reliability under demanding conditions.
- Industry Applications: Ideal for use in sectors such as petrochemical, power generation, metallurgy, food processing, environmental protection, and municipal pipeline systems, showcasing its broad application spectrum.
Technical Standards
- Design & Manufacturing: Adheres to industry-leading standards like JB/T 8937 and API 594, ensuring top-notch design and manufacturing quality.
- Flange Connections: Compatible with international standards such as GB/T 9113 and ASME B16.5, guaranteeing seamless integration.
- Testing & Certification: Rigorously tested to meet API 598 and GB/T 13927 protocols. Numerous manufacturers possess ISO 9001, API 6D, and other prestigious quality certifications.
Installation & Maintenance
- Flow Direction: Align the medium's flow with body arrow markings for correct installation. It supports both horizontal and vertical mounting applications.
- Support Requirements: Large valves necessitate independent supports to avoid pipeline stress, which could compromise sealing integrity.
Performance Parameters
- Flow Resistance Coefficient: Demonstrates a decrease as diameter increases (e.g., DN50: 2.6; DN1200: 0.7), ensuring smoother flow dynamics.
- Flow Capacity: The DN100 valve exhibits a remarkable flow capacity, with Kv=289 m³/h (Cv=338 per US standards), underscoring its high throughput efficiency.
Material Configuration
- Standard Options:
- Body: Constructed from WCB, 304/316 stainless steel.
- Disc & Spring: Crafted from durable stainless steel or alloy steel, ensuring longevity and optimal performance.
- Sealing Surface: Available with a choice of rubber or hard-faced alloy overlay, tailored to meet specific application needs.
The H71 Wafer Check Valve epitomizes incredible efficiency, unparalleled reliability, and exceptional adaptability across varied industrial pipeline systems. When making a final selection, consider the properties of the media, pressure/temperature conditions, and the specific installation environment. We encourage consulting manufacturer datasheets or reaching out to technical services for project-specific specifications and optimal performance insights.
