🌟 Engineering Advantages & Specifications
-
Innovative U-Shaped Ball Design: Utilizes the water's own weight instead of metal springs. This groundbreaking design allows the valve to be installed HORIZONTALLY or VERTICALLY with superior water-stopping performance and practically zero minimum water pressure required for a vertical seal.
-
Precision Rib Guides & Reinforced Seal: Internal ribs perfectly guide the half-ball for a stable seal, while an added support ring prevents the sealing gasket from deforming under pressure.
-
Lathe-Machined Surfaces: The contact surfaces of the socket and the sealing ring are precision lathe-machined to ensure absolute flatness and a flawless, seamless fit.
-
100% Metal-Free & Safe: Lead-free stabilizer formulation is non-toxic and odorless. Perfectly safe for drinking water, marine reef tanks, and corrosive liquids.
-
Technical Specs: Material: UPVC (Dark Grey) | Max Working Pressure: 150 PSI (equivalent to a 100-meter water column!) | Operating Temp: 0~45°C | Standards: ANSI, DIN, JIS, CNS.
⚠️ Sizing & Connection Guide (Crucial!)
-
🚨 SIZING LOGIC (Inner Dia. matches Outer Dia.): The sizes listed (e.g., 25mm) refer to the Inner Diameter (I.D.) of the socket ends. They sleeve OVER your rigid PVC pipes. Therefore, a 25mm I.D. valve perfectly connects to a PVC pipe with a 25mm Outer Diameter (O.D.).
-
Single Union Quick-Release: The threaded union nut allows you to easily detach the pipe section for future maintenance or cleaning without cutting glued pipes!
