Introduction to Axial Flow Check Valves
This series of axial flow check valves is an innovative design based on the principle of differential flow adjustable valves, serving as an upgraded replacement for traditional check valves. Its internal structure features a streamlined flow path and a flow guide element. Primarily installed at pump outlets or in pipelines requiring backflow prevention, it effectively eliminates water hammer impact and noise commonly generated during the closure of standard check valves. It ensures silent closing and provides exceptional sealing performance.The main check valve product names of China Check Valve Network include:Wafer Disc and Swing Check Valve，Socket Welded Forged Steel Lift Check Valve，Butterfly Buffering Check Valve，Flange Tiny Drag Slow Close Muffler Check Valve，Flange Tiny Drag Slow Close Butterfly Type Check Valve
Key Performance Features Check Valve Standard
1. Reliable Double Sealing: Utilizes a double-seal design, guaranteeing tight closure and excellent sealing performance regardless of downstream pressure—effectively addressing leakage issues common in traditional check valves under medium and low-pressure conditions.
2. Flexible and Controllable Operation: Achieves full opening even at relatively low flow rates. The opening/closing impedance is selectable for various requirements, typically enabling quick operation. Slow-closing structures can also be custom-designed upon request to meet specific system needs. Check Valve Suppliers
3. High Efficiency with Low Flow Resistance: The streamlined flow path and integrated flow guide element minimize fluid resistance, enhancing pipeline efficiency.Check Valve News
4. Premium Spring Material: Critical springs are designed in strict accordance with Class I standards and manufactured from stainless steel, ensuring long-term operational reliability and durability.
Installation and Usage Instructions
1. Installation Orientation: Flexible installation supports both horizontal and vertical mounting.
2. Pre-Installation Preparation: Thoroughly remove all debris and foreign matter from the pipeline before installation to prevent jamming or damage to the valve seat and disc. Installation of a filter upstream of the valve is recommended.
3. Flow Direction: During installation, adhere to the flow direction arrow marked on the valve body, ensuring it aligns with the actual medium flow.
4. Maintenance During Inactivity: When the valve is out of service for extended periods or when the medium in the pipeline is static, take anti-freezing measures and drain any residual water from the valve.
