Valterra ABS Gate Valve 3-Inch Hub x Spigot — Black RV Waste Valve, 15 PSI, Stainless Shaft

The Valterra ABS Gate Valve is a durable 3-inch hub x spigot waste valve designed to control RV and camper plumbing flow with corrosion-resistant materials and a leak-tight seal.

This gate valve brings reliable shutoff performance to your recreational vehicle or camper plumbing system. Built with a black ABS polymer body and hubs, plus a 304 stainless-steel shaft, it resists corrosion and mild chemicals common in waste plumbing setups. Engineered for everyday RV use, it balances ease of operation with a compact footprint and a secure gasketed seal to reduce the chance of leaks.

How strong is this valve for RV plumbing?

The Valterra gate valve is rated for up to 15 psi maximum working pressure and handles typical campsite waste-system conditions. It also carries a mid-flow rating and is designed for repeated open/close cycles without deforming under normal RV temperatures.

• Maximum pressure rating: 15 psi
• Mid-flow (operational) rating: 0.5 psi for routine usage
• Maximum working temperature: 167°F (75°C)

What materials make this valve last in outdoor use?

The body and hubs are molded from ABS plastic, chosen for toughness and resistance to water and mild chemical exposure. The internal shaft is 304 stainless steel, providing extra corrosion resistance where metal-to-plastic motion occurs. Sealing gaskets are installed to prevent leaks at the paddle and hub interfaces.

• Black ABS body and hubs resist corrosion and impact
• 304 stainless-steel shaft prevents rust on moving parts
• Pre-installed seal gaskets block gaps and reduce leakage risk

How does the 3-inch hub x spigot connection fit my system?

The valve uses a 3-inch hub x spigot configuration, a common size for RV waste plumbing and portable holding-tank setups. The paddle is slightly smaller than the opening to make opening and closing smooth, while the valve’s design ensures a tight fit when closed.

• Connection size: 3-inch hub x spigot — fits standard RV lines
• Slightly undersized paddle for easier operation without binding
• Hubs molded to accept typical clamps or solvent-weld methods

Will this valve prevent leaks and make maintenance simpler?

Yes — the valve ships with tight attachments and pre-installed gaskets to minimize leaks at installation and during use. Its plastic construction simplifies cleaning and reduces the need for frequent corrosion-related repairs, while the stainless shaft helps maintain smooth operation over time.

• Leak-minimizing gaskets installed at the seal points
• ABS surface is easy to rinse and inspect for wear
• Simple paddle movement makes winterizing and flushing easier

Who is this for? The Valterra ABS Gate Valve is aimed at RV owners, camper outfitters, and DIY van or trailer builders who need a reliable, corrosion-resistant 3-inch shutoff for waste or gray-water systems. It fits crews and individuals wanting a rugged yet affordable valve that’s easy to operate, easy to install with common RV plumbing methods, and built to withstand campsite conditions and routine maintenance.
