⚙️ Built for Tough Industrial Environments
-
Gravity Ball Mechanism: Eliminates vulnerable metal springs! Uses fluid weight and a precision-guided ball for an absolute seal with incredibly low flow resistance.
-
Lathe-Machined Surfaces: The contact surfaces are precision lathe-machined for absolute flatness, guaranteeing a flawless seal for corrosive liquids and high-pressure water lines up to 150 PSI (100-meter water column).
-
Technical Specs: Material: UPVC (Dark Grey) | Temp: 0~45°C | Standards: ANSI, DIN, JIS, CNS. (Note: CPVC materials with 95°C temp ratings are available for custom B2B wholesale orders. Contact support).
🚨 SIZING, IMAGE TYPO & INSTALLATION GUIDE!
-
⚠️ FACTORY IMAGE TYPO: Please ignore the "Swing Check Valve" text on the manufacturer's photo! As stated in the top right corner of the image, this is a BALL TYPE check valve.
-
⚠️ VERTICAL INSTALLATION ONLY: Because it relies on gravity to drop the massive internal ball, it MUST be installed strictly VERTICALLY! If installed horizontally, it will fail to close.
-
Sizing Logic: The sizes listed (e.g., 110mm) refer to the Inner Diameter (I.D.) of the sockets, designed to sleeve OVER matching PVC pipes using industrial PVC cement.
