    Premium SanKing UPVC True Union Swing Check Valve

    Protect your vital pumps and prevent catastrophic back-siphoning with the heavy-duty SanKing True Union Swing Check Valve from Atradesen.com. Engineered for professional aquariums, marine reef sumps, and industrial liquid transport, this double-disconnect flapper valve ensures water only flows in one direction while offering unmatched durability and ease of maintenance.

    🌟 Industrial-Grade Flap Design & Easy Maintenance

    • Swing Flapper Mechanism: Unlike spring-loaded valves that restrict flow, this advanced swing/flap design offers extremely low water resistance. It can be installed HORIZONTALLY or VERTICALLY with superior sealing performance and minimal pressure requirements.
    • True Union Quick-Release: Features threaded union nuts on BOTH ends. Instantly detach the entire central valve body for cleaning or replacement without ever needing to cut your glued PVC pipes!
    • 150 PSI & 100% Metal-Free: Built to withstand massive industrial pressures up to 150 PSI. The completely metal-free UPVC construction means it will never rust, making it 100% safe for saltwater reef tanks and drinking water systems.

    ⚠️ Sizing & Installation Guide (Crucial!)

    Ensure a flawless, leak-proof setup by reviewing the Atradesen.com guidelines below:

    • 🚨 DIRECTIONAL ARROW: Check valves are strictly one-way! You MUST install the valve so the molded arrow on the body points in the direction of your pump's water flow.
    • 🚨 SIZING LOGIC (Inner Dia. matches Outer Dia.): The sizes listed in the dropdown menu (e.g., 25mm) refer to the Inner Diameter (I.D.) of the two union sockets. They are designed to sleeve OVER your rigid PVC pipes.
    • Installation: PVC waterproof adhesive/glue MUST be used on the outer slip joints to secure your pipes permanently to the union halves.
