Product Overview
Discover the ultimate in reliability with our industrial-grade stainless steel threaded check valve, an elite automatic non-return valve engineered for excellence in liquid and gas pipeline systems. Crafted from high-quality stainless steel, this valve offers unparalleled corrosion resistance, formidable high-pressure tolerance, and remarkable thermal stability. It is the ideal choice for rigorous applications in the chemical processing, petroleum, water treatment, and HVAC industries. The valve is designed to ensure unidirectional flow, safeguarding your crucial equipment from the perils of backflow damage.
Construction & Design
1. Materials
- Body/Bonnet: Precision-crafted from 304/316 stainless steel, offering unmatched corrosion resistance
- Disc: Constructed from durable stainless steel or robust reinforced engineering polymer (POM) for enhanced longevity
- Seals: Choose from EPDM, NBR, or FKM for optimal media compatibility across diverse environments
- Connection: Threaded in G/NPT/BSP standards, ensuring a secure and reliable installation experience
2. Key Features
- Spring-assisted closure: Available in select models, ensures rapid response and prevents water hammer with precision
- Low-pressure drop: Ingeniously optimized flow path design drastically reduces system resistance
- Compact footprint: Designed to save space, ideal for installations where space is at a premium
- Maintenance-free operation: A self-actuating mechanism that requires no external control, promoting ease of use
Operating Principle
Operating seamlessly on differential pressure, the valve allows fluid pressure to lift the disc for forward flow. Reverse flow is automatically arrested by the disc being closed via gravity, spring force, or backpressure, effectively preventing backflow.
Technical Specifications
- Media Compatibility: Tailored for water, oils, steam, gases, and mild corrosive fluids
- Pressure Rating: 0.6-4.0 MPa, with higher ratings available for more demanding conditions
- Temperature Range: -20°C to 180°C, contingent on seal material, accommodating various operational needs
- Connection Sizes: DN15-DN100 (½"-4"), with custom sizes available to suit specific requirements
- Cracking Pressure: Adjustable between 0.05-0.1 MPa in spring-assisted models for precise control
Typical Applications
- Petrochemical: Ideal for pipeline transport and tank inlets/outlets
- Water Treatment: Perfect for pump discharges, filtration systems, and desalination processes
- HVAC: Reliable for boiler feedwater and cooling circuit applications
- Food/Pharma: Suited for sanitary pipelines, available in GMP-compliant versions
- Industrial Machinery: Suitable for compressors, hydraulic systems, and fire protection setups
Product Advantages
1. Superior Reliability: With corrosion-resistant construction, it ensures performance that is as watertight as it is dependable
2. Reduced Maintenance: The self-operating design significantly minimizes service and upkeep requirements
3. Broad Compatibility: Engineered to suit a wide variety of media and piping standards seamlessly
4. System Protection: Spring-assisted models effectively mitigate hydraulic shock, preserving system integrity
Installation & Maintenance
- Orientation: Install corresponds with the flow arrow to match the direction of media
- Maintenance: Regular inspection of disc movement and seal integrity is recommended to ensure optimal performance
