Product Overview
Introducing the H71 Wafer Check Valve-a marvel of modern engineering crafted to elevate performance in water, oil, and gas solutions. Its sleek, compact wafer connection design stands out, boasting a structural length that is merely 1/4 to 1/8 of traditional flange check valves, making it significantly lighter and smaller, weighing just 1/4 to 1/20 of conventional counterparts. This innovative valve provides rapid closure to effectively mitigate the notorious water hammer effects, offers low fluid resistance, and brings unparalleled adaptability to both horizontal and vertical pipeline installations. Say goodbye to the cumbersome bulk of H41 flange check valves-the H71 revolutionizes with ease of installation and maintenance, resolving traditional challenges seamlessly.
Structural Features
- Fast Closure: Our spring-loaded disc design ensures swift, short-stroke closure, dramatically reducing harmful water hammer pressure in high-flow scenarios.
- Sealing Performance: The single-disc vertical movement, enhanced by a spring-assisted sealing mechanism, guarantees zero leakage and promises an extended service life.
- Material Versatility: Crafted with precision, the components-be it the body or the disc-are available in carbon steel, stainless steel (304/316/316L), duplex steel, and more, tailored to meet diverse media requirements.
Application Range
- Media Compatibility: Exceptionally versatile, our valve is suited for water, steam, oil, nitric acid, acetic acid, strongly oxidative media, and urea. The thoughtful material selection further extends its compatibility to withstand even the most corrosive environments.
- Operating Parameters:
- Pressure Rating: PN10-PN420 (Class150-Class2500)
- Size Range: DN15-DN600
- Temperature Range: -196°C to 540°C
- Industry Applications: A stalwart in versatility, the valve finds its place in industries such as petrochemical, power generation, metallurgy, food processing, environmental protection, and municipal pipeline systems.
Technical Standards
- Design & Manufacturing: Proudly built to the rigorous standards of JB/T 8937, API 594, and more, ensuring supreme reliability.
- Flange Connections: Designed to seamlessly integrate with GB/T 9113, ASME B16.5, and other esteemed international standards, guaranteeing universal application.
- Testing & Certification: Adheres strictly to API 598, GB/T 13927 test protocols, with select manufacturers boasting ISO 9001, API 6D certifications, and beyond, ensuring top-tier quality assurance.
Installation & Maintenance
- Flow Direction: For optimal performance, align medium flow with body arrow markings. The design accommodates both horizontal and vertical mounting with ease.
- Support Requirements: Large valves necessitate independent supports to safeguard against pipeline stress, preserving the integrity of the sealing.
Performance Parameters
- Flow Resistance Coefficient: Ingeniously engineered to decrease with increasing diameter, offering values such as DN50: 2.6 and DN1200: 0.7, ensuring smooth flow.
- Flow Capacity: With a spectacular flow capacity, the DN100 valve showcases a Kv of 289 m³/h (equivalent to a Cv of 338 per US standards), epitomizing high throughput efficiency.
Material Configuration
- Standard Options:
- Body: Choose from durable WCB or high-grade 304/316 stainless steel for robust performance.
- Disc & Spring: Crafted in resilient stainless steel or alloy steel to withstand demanding conditions.
- Sealing Surface: Options include rubber or a hard-faced alloy overlay for superior sealing reliability.
The H71 Wafer Check Valve stands as a beacon of efficiency, reliability, and adaptability in the realm of industrial pipeline systems. For the optimal selection, consider the specific media properties, pressure and temperature conditions, and the installation environment. We recommend consulting manufacturer datasheets or technical services to tailor specifications precisely to your project's needs.
