Premium UPVC Bolted Swing Check Valve
Protect your water pumps and prevent catastrophic back-siphoning floods with the Bolted UPVC Swing Check Valve from Atradesen.com. Engineered for professional sumps, marine reef tanks, and critical water supply lines, this highly reliable non-return valve features a robust bolted housing, ensuring water only flows in one direction while withstanding significant system pressure.
🌟 Advanced Flap Design & Durability
-
Heavy-Duty Bolted Housing: Unlike cheap glued or threaded valves, the two halves of this valve are securely clamped together with stainless steel bolts, allowing for extreme pressure resistance and future disassembly for maintenance.
-
Low Flow Resistance: The swinging flap design creates significantly less water friction and head pressure loss than spring-loaded valves, resulting in a smoother operation that won't choke your pump's output.
-
100% Rust-Proof Core: Constructed purely from chemical-grade UPVC with zero internal metal parts. Safe for saltwater reef aquariums.
🚨 CRUCIAL INSTALLATION & WATER PRESSURE GUIDE!
To ensure a 100% leak-proof seal, you MUST match your installation angle to your pump's water pressure. Read the Atradesen.com rules below:
-
⚠️ DIRECTIONAL ARROW: You MUST install the valve so the molded arrow points in the direction of your pump's water flow!
-
🚨 HIGH WATER PRESSURE (Vertical Mount OK): If your water pump is very powerful, you can install this valve vertically. The strong water flow will push the flap open, and the strong gravity backpressure will snap it shut.
-
🚨 LOW WATER PRESSURE (Horizontal Mount REQUIRED): If you are using a low-wattage pump or have weak water flow, you MUST install this valve horizontally (flat)! In a vertical setup, a weak pump may struggle to push the heavy flap open, and weak backpressure will fail to seal it. Horizontal mounting allows gravity to help seal the flap perfectly.
-
Sizing Logic: The sizes listed (e.g., 32mm) refer to the Inner Diameter (I.D.) of the sockets, which sleeve OVER matching PVC pipes.
