Valterra 1.5 Inch Gate Valve (Slip / MPT) – Dump Valve (20-0665)
Command absolute, leak-proof control over your mobile fluid management systems with the legendary reliability of the Valterra 1.5 Inch Gate Valve (20-0665). In commercial portable carpet extractors, RV grey-water tanks, and specialized industrial plumbing, standard ball valves frequently become clogged with heavy debris and hair. This premium dump valve features a highly efficient sliding 'gate' (or guillotine) mechanism. When you pull the heavy-duty T-handle, the internal plastic blade retracts entirely out of the fluid path, providing a massive, 100% unrestricted 1.5-inch opening. This guarantees that thick, dirty water, carpet lint, and heavy sludge drain instantly and flawlessly without ever causing a blockage.
Precision connection compatibility is critical for a fast, secure installation. This specific Valterra model features a highly versatile Slip / MPT fitting configuration. One side is a standard smooth 'Slip' hub (designed to be permanently glued to a 1.5-inch PVC pipe), while the other side features a Male Pipe Thread (MPT), allowing it to be securely screwed into a threaded female port on a machine tank. Manufactured in North America from ultra-durable ABS plastic and featuring heavily lubricated internal rubber seals, this authentic valve replacement kit guarantees years of smooth, leak-free operation for professional carpet cleaners and RV mechanics.
Who Is This Valterra 1.5-Inch Gate Valve Ideal For?
The 20-0665 Valterra Valve delivers an unrestricted fluid path and versatile Slip/MPT connections. It is highly recommended for:
-
Commercial Carpet Cleaners: Installing a highly reliable dump valve onto the dirty-water recovery tanks of their portable carpet extraction machines to ensure heavy carpet lint and mud drain instantly without clogging.
-
RV & Caravan Mechanics: Utilizing a premium, leak-proof valve replacement kit to repair or build grey-water waste holding tanks, ensuring completely sanitary, mess-free dumping at caravan parks.
-
Industrial Plumbers: Implementing a massive, unrestricted fluid gate in low-pressure agricultural or chemical management systems where standard ball valves would be destroyed by heavy suspended solids.
-
Marine & Boat Builders: Sourcing heavy-duty, corrosion-resistant ABS plastic valves to safely manage onboard grey-water holding tanks without rusting in harsh saltwater environments.
Key Features and Performance Benefits:
-
Unrestricted Fluid Path: The sliding guillotine gate pulls completely out of the way. Unlike ball valves that restrict flow, this provides a full 1.5-inch open pipe, allowing heavy debris, lint, and thick sludge to dump instantly.
-
Slip / MPT Connections: Highly versatile installation. Glue standard 1.5" PVC pipe directly into the smooth 'Slip' side, and screw the 'MPT' (Male Pipe Thread) side into a threaded tank fitting for a secure, watertight assembly.
-
100% Leak-Proof Seals: The internal sliding blade is flanked by heavy-duty, chemical-resistant rubber seals. These gaskets clamp tightly against the blade when closed, guaranteeing absolutely zero dirty water drips.
-
Heavy-Duty ABS Construction: The main body and the pull-handle are manufactured from thick, industrial-grade ABS plastic. It is completely immune to rust and aggressively resists cracking under physical impact.
