Premium UPVC Pull-Push Sewage Gate Valve
Experience rapid, unrestricted wastewater dumping and effortless flow control with the UPVC Pull-Push Gate Valve from Atradesen.com. Often called a "knife valve" or "dump valve", this specialized fitting features a simple pull-up/push-down mechanism. It is the absolute perfect choice for aquarium sump drains, Koi pond waste purging, and low-pressure sewage lines where heavy solids and fish waste would easily clog a standard ball valve.
🌟 Advanced Zero-Clog & Quick-Dump Design
-
Rapid Push-Pull Operation: Instantly open or close the valve by simply pulling the T-handle up or pushing it down. No stiff twisting required! Perfect for tight under-cabinet spaces where turning a large handle is impossible.
-
Lockable Positioning Nut: Features a built-in locking nut on the stem. Once you find your desired flow rate, twist the nut to lock the handle firmly in place, preventing accidental closing or opening.
-
Straight-Through Flow (Zero Resistance): When fully pulled open, the gate lifts entirely out of the water path. This allows raw sewage, large fish waste, and thick sludge to pass through freely without causing clogs or flow loss.
🚨 CRUCIAL PRESSURE & INSTALLATION WARNINGS!
This is a specialized LOW-PRESSURE drain valve. Please read the Atradesen.com rules carefully to prevent catastrophic blowouts:
-
⚠️ LOW PRESSURE ONLY (MAX 0.35 MPA): This valve is strictly designed for gravity drains, wastewater purging, and low-pressure systems (equivalent to standard tap water pressure). DO NOT install this on a high-pressure pump return line! It will leak or blow out!
-
🚨 SIZING LOGIC (Inner Dia. matches Outer Dia.): The sizes listed (e.g., 50mm) refer to the Inner Diameter (I.D.) of the two socket ends. They sleeve OVER your rigid PVC pipes.
-
Installation: Heavy-duty industrial PVC cement MUST be used on all slip joints to secure your pipes permanently.
