Product Overview
Discover our high-caliber industrial-grade stainless steel threaded check valve, an elite choice for automatic non-return applications within liquid and gas pipeline systems. Crafted from superior-quality stainless steel, this valve boasts outstanding resistance to corrosion, can withstand high pressures, and maintains thermal stability, making it the perfect solution for rigorous applications in chemical processing, petroleum, water treatment, and HVAC systems. This valve ensures unidirectional flow, safeguarding critical equipment against the potential hazards of backflow damage.
Construction & Design
1. Materials
- Body/Bonnet crafted from 304/316 stainless steel, providing unparalleled corrosion resistance.
- Disc made of stainless steel or reinforced engineering polymer (POM), designed for long-lasting durability.
- Seals available in EPDM, NBR, or FKM options, offering versatile media compatibility.
- Threaded connections (G/NPT/BSP standards) ensure a secure and reliable installation.
2. Key Features
- Select models offer a spring-assisted closure for rapid response and prevention of water hammer issues.
- The optimized flow path design results in a low-pressure drop, minimizing system resistance effectively.
- Its compact footprint is ideal for installations with space constraints, maximizing efficiency.
- Experience maintenance-free operation with the self-actuating mechanism that requires no external control.
Operating Principle
This valve leverages differential pressure, where fluid pressure lifts the disc to permit forward flow. Conversely, reverse flow automatically triggers the closing of the disc through gravity, spring force, or backpressure, effectively preventing backflow.
Technical Specifications
- Compatible with a variety of media, including water, oils, steam, gases, and mildly corrosive fluids.
- Pressure Rating ranges from 0.6 to 4.0 MPa, with higher ratings available for customized needs.
- Capable of operating within a temperature range of -20°C to 180°C, dependent on the seal material used.
- Connection Sizes available from DN15 to DN100 (½"-4"), with custom sizes available upon request.
- Cracking Pressure can be adjusted from 0.05 to 0.1 MPa in spring-assisted models, offering tailored performance.
Typical Applications
-Petrochemical: Ideal for pipeline transport and tank inlets/outlets, enhancing operational efficiency.
-Water Treatment: Perfect for pump discharges, filtration systems, and desalination processes.
-HVAC: Efficiently used in boiler feedwater and cooling circuits, ensuring optimal performance.
-Food/Pharma: Suitable for sanitary pipelines, with GMP-compliant versions available for stringent requirements.
-Industrial Machinery: Utilized effectively in compressors, hydraulic systems, and fire protection services.
Product Advantages
1. Superior Reliability: Its corrosion-resistant construction guarantees leak-free performance, promoting longevity.
2. Reduced Maintenance: The self-operating design significantly lowers the need for regular service.
3. Broad Compatibility: Designed to be universally suitable for diverse media and piping standards.
4. System Protection: Spring-assisted models are effective in mitigating hydraulic shock, preserving system integrity.
Installation & Maintenance
