Product Overview
Introducing the innovative H71 Wafer Check Valve, a marvel of compact engineering that redefines efficiency and convenience. Its sleek wafer connection design boasts a remarkable structural length, just a fraction of traditional flange check valves, significantly trimming down both size and weight. Imagine a valve that's only 1/4 to 1/20 the weight of its conventional counterparts! This transformation doesn't just stop at aesthetics; it's about performance. Experience the benefits of rapid closure that curtail water hammer effects, enjoy the ease of low fluid resistance, and revel in its adaptability across both horizontal and vertical pipelines. Compared to the cumbersome H41 flange check valves, the H71 type triumphs over bulkiness and resolves installation and maintenance headaches inherent in older designs.
Structural Features
- Rapid Closure: The precision-engineered, spring-loaded disc ensures swift, short-stroke closure, a game-changer in reducing water hammer pressure, especially in high-flow environments.
- Superior Sealing Performance: Thanks to its single-disc vertical movement, combined with spring-assisted sealing, this valve guarantees zero leakage and promises an extended service life.
- Versatile Material Options: Crafted to meet diverse media needs, the components, including the body and disc, are available in a range of materials such as carbon steel, stainless steel (304/316/316L), and duplex steel.
Application Range
- Broad Media Compatibility: From water, steam, and oil to nitric acid, acetic acid, highly oxidative media, and urea, this valve excels. Tailored material selection extends its prowess to corrosive environments.
- Operating Parameters:
- Pressure Range: Effortlessly handles ratings from PN10-PN420 (Class150-Class2500)
- Size Versatility: Available in a wide range from DN15 to DN600
- Temperature Tolerance: Performs reliably from -196°C to 540°C
- Industry Applications: Encompassing petrochemical, power generation, metallurgy, food processing, environmental protection, to municipal pipeline systems, this valve is indispensable.
Technical Standards
- Design & Manufacturing: Adheres to the rigorous standards of JB/T 8937, API 594, ensuring quality and durability.
- Flange Connections: Compatible with international standards including GB/T 9113, ASME B16.5, and more.
- Testing & Certification: Conforms to API 598, GB/T 13927 testing protocols, with top manufacturers earning ISO 9001, API 6D, and other prestigious certifications.
Installation & Maintenance
- Proper Flow Direction: Align media flow with body arrow markings; suitable for both horizontal and vertical installations.
- Support Considerations: Large valves demand independent supports to safeguard against pipeline stress affecting sealing integrity.
Performance Parameters
- Flow Resistance Coefficient: As diameter increases, the coefficient decreases (e.g., DN50: 2.6; DN1200: 0.7), optimizing flow efficiency.
- Impressive Flow Capacity: The DN100 valve showcases a Kv of 289 m³/h (Cv equivalent to 338 per US standards), exemplifying its high throughput prowess.
Material Configuration
- Standard Material Options:
- Body: Choose from materials like WCB, 304/316 stainless steel.
- Disc & Spring: Available in durable stainless steel or alloy steel.
- Sealing Surface: Options include rubber or a hard-faced alloy overlay for added resilience.
The H71 Wafer Check Valve stands as a paragon of efficiency, reliability, and versatility, crafted for the demands of industrial pipeline systems. When selecting, consider media properties, pressure/temperature conditions, and installation environment. For precise specifications, consult manufacturer datasheets or technical services.
