When it comes to plumbing shut-off valves, reliability, ease of installation, and long-term performance are critical. The Dahl 611-13-31 Mini-Ball™ Valve delivers on all fronts, offering a durable, compact, and highly versatile shut-off solution. Built by Dahl Brothers Canada, a trusted name in plumbing components, this valve is designed for professional plumbers, contractors, and DIY installers who need dependable performance.
This valve features a lead-free brass body with a corrosion-resistant chrome-plated finish, ensuring compliance with North American potable water standards. The compact “mini” design makes it ideal for use in tight or concealed spaces, such as under sinks, inside cabinets, or behind toilets, where space is often at a premium.
The female solder inlet allows the valve to be securely connected to 1/2" copper pipe using a sweat/solder joint, providing a permanent and durable connection. On the outlet side, the valve is equipped with a 3/8" OD compression fitting, commonly used for supply lines to faucets, toilets, and similar fixtures. This combination of solder and compression makes the valve highly versatile in residential and light commercial applications.
At the heart of the 611-13-31 is Dahl’s quarter-turn ball valve mechanism. Unlike traditional multi-turn valves that can wear down over time, the quarter-turn design provides instant shut-off and smooth operation with a simple 90-degree turn of the handle. This makes servicing and emergency shut-offs quick and hassle-free.
