Product Overview
Introducing the H71 Wafer Check Valve, a marvel of modern engineering crafted for those who prioritize efficiency and innovation! This state-of-the-art valve features an ingenious wafer connection design that optimally reduces the structural length to a mere fraction-1/4 to 1/8-of traditional flange check valves, setting a new standard in compact size and lighter weight. It is strikingly lightweight, weighing just 1/4 to 1/20 of conventional counterparts. Revel in its fast-acting closure mechanism that effectively diminishes the threat of water hammer while maintaining impressively low fluid resistance. Expertly designed for effortless installation in both horizontal and vertical pipelines, the H71 Wafer Check Valve effortlessly surpasses the bulk and maintenance demands of traditional H41 flange check valves. This is your invitation to revolutionize pipeline efficiency with the cutting-edge H71-a forward-thinking solution for today's demanding environments.
Structural Features
- Experience the pinnacle of rapid responsiveness with our Fast Closure feature. The spring-loaded disc enables swift, short-stroke closure that significantly reduces water hammer pressures, even under high-flow conditions, ensuring your systems remain protected.
- Our Sealing Performance is unparalleled and reliable. The vertically movable single-disc, assisted by a spring mechanism, guarantees a flawless seal, zero leaks, and an impressively prolonged service life, making it a worthy investment for any application.
- Embrace the power of Material Versatility with a selection including carbon steel, stainless steel (304/316/316L), and duplex steel. This flexibility allows precise customization of components such as the body and disc, catering to diverse media requirements with ease.
Application Range
- Media Compatibility is virtually limitless! The H71 Wafer Check Valve is engineered for use with water, steam, oil, nitric acid, acetic acid, highly oxidizing media, and urea. Its material flexibility extends its use to even the harshest and most corrosive environments.
- Operating Parameters:
- Pressure Rating: Built to withstand a formidable range from PN10 to PN420 (Class150 to Class2500), ensuring robust adaptability to various pressure demands.
- Size Range: Offers a versatile array of sizes from DN15 to DN600, ensuring perfect fitment for any application you encounter.
- Temperature Range: Offers extraordinary adaptability from a bone-chilling -196°C to a blistering 540°C, demonstrating its resilience and flexibility across extreme conditions.
- Industry Applications: Proudly elevates operational standards across industries including petrochemical, power generation, metallurgy, food processing, environmental protection, and municipal pipeline systems, delivering excellence in every sphere.
Technical Standards
- Design & Manufacturing: Rigorously adheres to JB/T 8937 and API 594 standards, embodying top-tier craftsmanship and reliability you can trust.
- Flange Connections: Seamlessly integrates with GB/T 9113, ASME B16.5, and other globally recognized standards, ensuring universal compatibility.
- Testing & Certification: Meets the stringent requirements of API 598, GB/T 13927 testing protocols. Manufacturers with ISO 9001 and API 6D certifications further underscore our commitment to quality excellence and assurance.
Installation & Maintenance
- Flow Direction: Achieve seamless, intuitive installation by aligning the medium flow with body arrow markings for straightforward horizontal or vertical mounting.
- Support Requirements: For larger valves, independent support systems are essential to prevent undue stress on the pipeline, preserving sealing integrity and safeguarding long-term performance.
Performance Parameters
- Flow Resistance Coefficient: Innovatively engineered to decrease with increasing diameter, exemplified by DN50 at 2.6 and DN1200 at a mere 0.7, significantly enhancing operational efficiency.
- Flow Capacity: Showcases impressive throughput efficiency, with the DN100 valve achieving a Kv=289 m³/h (equivalent to Cv=338 per US standards), ensuring superior flow performance.
Material Configuration
- Standard Options:
- Body: Choose from robust WCB or 304/316 stainless steel to ensure unmatched durability and longevity.
- Disc & Spring: Available in high-performance stainless steel or alloy steel, providing exceptional resilience and dependability.
- Sealing Surface: Opt between durable rubber or hard-faced alloy overlay for superior sealing performance tailored to your needs.
