Product Overview
Discover the exceptional H76 Wafer-Type Dual Disc Check Valve, an automatic marvel crafted to safeguard your systems from medium backflow. Its wafer-style connection ensures seamless integration into your pipeline systems, making it an indispensable component in petroleum, chemical, power, water supply, and drainage scenarios. Constructed from high-quality stainless steel (e.g., 304, 316) or cost-effective carbon steel (WCB), this valve promises superior corrosion resistance, impressive high-pressure capabilities, and swift, efficient opening/closing operations.
Structure and Working Principle
- Dual Disc Design: Engineered with two perfectly symmetrical discs pre-tensioned by springs to promote rapid closure, this innovation effectively minimizes the impact of water hammer, ensuring system longevity.
- Wafer-Style Installation: The innovative flangeless design allows the valve body to be securely clamped between pipeline flanges using bolts, optimizing space and making it the perfect choice for compact piping configurations.
- Operation: In forward flow mode, fluid pressure effortlessly opens the discs. As flow ceases or reverses, the discs instantly close, driven by spring force and reverse pressure, effectively blocking any backflow.
Key Features
- Low Water Hammer Effect: Designed with a split-disc mechanism, this valve significantly reduces closing impact, safeguarding the integrity of your pipeline system.
- Lightweight and Efficient: This valve is 30%~50% lighter than traditional check valves, facilitating easy installation and maintenance without compromising on performance.
- Reliable Sealing: Choose from rubber, PTFE, or robust metal-to-metal hard sealing for unrivaled compatibility with a variety of mediums including water, steam, oils, and more.
- Versatility at Its Best: Stainless steel options are tailored for corrosive environments like seawater and acids, while carbon steel is perfect for standard conditions, offering a cost-effective solution.
Applications
- Integral to municipal water supply and drainage systems, ensuring smooth, uninterrupted service.
- Essential for petrochemical pipelines, guaranteeing operational safety and efficiency.
- Vital for thermal power plant cooling water circulation, maintaining optimal system temperatures.
- Perfectly suited for HVAC systems, providing reliable backflow prevention.
- Engineered for marine and offshore platforms, delivering steadfast performance in demanding environments.
Selection and Installation Guidelines
- Selection Criteria: Carefully choose material and seal type based on medium characteristics (corrosivity, temperature), pressure demands, and pipe size for optimal performance.
- Installation Direction: Ensure proper alignment of the valve arrow with the flow direction; adaptable for both horizontal and vertical setups.
- Maintenance: Conduct regular inspections of disc springs and seal surfaces to ensure longevity; prevent debris accumulation for sustained performance.
The H76 Wafer-Type Dual Disc Check Valve distinguishes itself with a compact design, rapid response, and minimal maintenance needs, making it an ideal choice for backflow prevention in environments where space is at a premium or where systems operate frequently. Achieve peak performance by matching materials and sealing solutions to the precise demands of your operating conditions.
