🌟 Advanced Diaphragm Isolation Technology
-
Total Fluid Isolation: Unlike standard valves, this uses a flexible internal diaphragm to physically separate the water from the upper mechanical driving gears. Your fluid NEVER touches the turning mechanism! This prevents corrosion, eliminates stem leaks, and ensures extreme safety for both your equipment and your livestock.
-
Precision Micro-Tuning: Turning the top handle pushes the diaphragm down gradually, allowing for infinitely precise, smooth adjustments to your water flow rate—perfect for tuning Herbie or BeanAnimal overflows.
-
True Union Quick-Release: Features threaded union nuts on both ends. Easily detach the center body for maintenance or to replace the internal diaphragm pad without cutting any glued PVC pipes!
⚠️ 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 fitting.
-
How It Works: These sockets are designed to sleeve OVER your rigid PVC pipes. Therefore, a DN20 (25mm I.D.) valve perfectly connects to a 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).
