The Swing Check Valve is designed to prevent backflow in industrial systems by automatically closing when the flow stops. With its rising stem design, the position of the valve can be clearly observed, making it easy to operate and monitor.
Constructed from high-quality cast steel (WCB) or stainless steel (CF8/CF8M), this valve offers superior resistance to corrosion and wear, ensuring a long service life even in demanding environments. It features a flanged connection for easy installation and secure sealing, and is available in a wide range of sizes (DN50 to DN300).
The valve's soft or metal sealing ensures a tight shutoff to prevent leakage, and its high-pressure capability (PN16/PN40) allows it to function effectively in various industrial applications. Whether used in water treatment facilities, oil & gas pipelines, or petrochemical plants, the Swing Check Valve is designed to deliver reliable performance and enhanced safety.
Features
- Rising Stem Design: The rising stem design allows easy visual indication of the valve's position (open or closed), ensuring efficient operation.
- High-Quality Cast Steel: Constructed from cast steel (WCB) or stainless steel (CF8/CF8M), providing excellent strength, corrosion resistance, and durability.
- Flanged Connection: Standard flanged connections (RF, RTJ) ensure easy installation and secure sealing in various piping systems.
- Positive Shutoff: The valve closes automatically when the flow stops, preventing backflow and ensuring optimal system protection.
- Wide Application: Ideal for various industries including water treatment, oil & gas, petrochemical, and power plants, handling liquids and gases.
- Multiple Pressure Ratings: Supports PN16 and PN40 pressure ratings, making it suitable for both medium and high-pressure applications.
- Temperature Compatibility: Operates within a broad temperature range from -29°C to 200°C, suitable for different media and environmental conditions.
- International Standard Compliance: Designed and manufactured to meet API 594, ASME B16.34, and other global industry standards, ensuring reliability and safety.
