I. Product Overview
ThePipe-Type Check Valve S15Ais an automatic valve designed to prevent fluid backflow, widely used in hydraulic systems. It relies on fluid pressure to automatically open and close, ensuring unidirectional flow and protecting system components from reverse flow impact and damage.
II. Product Features
1. Automatic Control: The valve disc opens and closes automatically via fluid pressure, requiring no external power source.
2. Compact Structure: Simple design with a small footprint and lightweight construction for easy installation and maintenance.
3. Reliable Sealing: Utilizes high-quality sealing materials to ensure tight closure, preventing fluid leakage.
4. Low Flow Resistance: Smooth fluid passage when open, minimizing resistance and reducing system energy consumption.
5. Wide Applicability: Suitable for various media (e.g., hydraulic oil, water, steam) and operates stably across a broad temperature and pressure range.
III. Technical Parameters
• Nominal Diameter: 15 mm (varies by model; confirm based on actual product specifications).
• Working Pressure: Typically rated for high-pressure applications, such as25 MPa or higher(depending on design and manufacturing standards).
• Operating Temperature: Range varies by sealing material and body construction, generally-20°C to 120°C.
• Connection Type: Threaded or flanged connections for compatibility with piping systems.
IV. Application Fields
ThePipe-Type Check Valve S15Ais widely used in:
• Industrial Hydraulic Systems: Prevents backflow in equipment like machine tools, injection molding machines, and die-casting machines.
• Energy & Chemical Industries: Ensures safe operation in pipelines for oil, gas, and chemicals by preventing reverse flow.
• Water Treatment: Protects treated water quality by blocking backflow into untreated zones.
• Other Sectors: Agricultural irrigation, marine hydraulic systems, and other applications requiring unidirectional flow control.
V. Selection & Installation Considerations
1. Selection Criteria: Choose based on system parameters such as pressure, flow rate, and media type.
2. Installation Orientation: Align the valve with the fluid flow direction (arrow indicates forward flow).
3. Piping Cleanliness: Ensure the pipeline is clean before installation to avoid contaminants entering the valve.
4. Regular Inspection: Periodically check sealing performance and operational flexibility; replace damaged seals or discs promptly.
