🌟 Visual Monitoring & Total Control

• Crystal Clear Valve Body: Provides a direct window into your fluid dynamics. You can actually see the internal ball core turn and visually verify that the valve is completely sealed or fully open!
• 100% Full Shut-Off: Features a high-quality internal spherical core that creates an impenetrable seal when closed. Essential for isolating plumbing lines during pump cleaning or equipment maintenance without any leaks.
• Industrial Grade & Safe: Manufactured from premium drinking-water-grade UPVC. Highly resistant to corrosive liquids, chemicals, and saltwater.

⚠️ Sizing & Connection Guide (Crucial!)

Avoid ordering the wrong size! Please read the Atradesen.com connection rules carefully:

• 🚨 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 socket ends on the valve.
• How It Works: These sockets are designed to sleeve OVER your rigid PVC pipes. Therefore, a 25mm I.D. valve perfectly connects to a clear PVC pipe with a 25mm Outer Diameter (O.D.).
• Installation: PVC waterproof adhesive/glue MUST be used on the slip joints to secure your pipes permanently (glue not included).
