mini-ball™ Valves

dahl pioneered the ¼-turn mini-ball™ valve supply stop for North America in 1984. We’ve continued that tradition of innovation over the past 40 years, introducing products like female compression connections that work with existing stops or fittings. Our modular mini-ball™ design was developed by our in-house engineers, but every product we build is guided and perfected by feedback from plumbers in the field.

“I don’t buy any other valves now aside from dahl. Their angle and straight shut offs are bulletproof! Thank you for making it easy for me to sleep at night knowing I have high quality product in all my clients homes.”

-Robert Pinkney, Oakview Plumbing LTD

“The quality of dahl valves gives us peace of mind.  We’ve never seen one fail.  They’re competitively priced… for my money the best value in the plumbing business. We can’t switch from dahl, because our techs would freak out if we tried to make them use anything else.”

Devin Carel, Anderson Plumbing, Heating & Air, San Diego, CA

“To me, dahl valves are perfect… priced right, easy to work with, and they never leak.  Their 3-way Universal Tee is awesome, particularly under a kitchen sink.  dahl makes my job easier, every day.”

Tim Paris, Paris Plumbing, Seattle, WA

“The quality of a plumbing fixture is really only as good as the valves behind it.  When I discovered dahl, I knew I’d found a product line with quality that’s equal to any other install.  dahl valves are solid, easy to work with and covered by a LifeTime Warranty.  Who else can say that?”

Roger Peugeot, Roger the Plumber, Overland Park, KS

“To keep our journeymen happy, it’s dahl or nothing!  They’re a little spoiled, because dahl valves are so easy to work with, and so reliable.  We want our customers to have the very best.  That’s why our trucks start the day loaded with dahl valves.”

Vince Marino and Dawn Kennell, Vince Marino Plumbing, Finksburg, MD

“The most important thing our business has is its reputation.  That’s why we always recommend premium products like dahl valves.  All you need to do is pick up the valve to feel superior quality.  Every dahl valve we install is good for our reputation, and helps our business grow.”

Don Caughlin, My Plumber Heating & Air, Manassas, VA

We’ve used dahl for 10 years because of reliability. If a valve installed out of sight starts leaking, it could be months before it’s noticed. That’s a disaster. dahl quality is so good after 10 years we haven’t seen a leaker. We run 60 trucks, so I figure dahl has saved us thousands of dollars in callbacks we didn’t have to make.  We’ll never switch.

Bill Hawes, San Diego, CA

Have never had any issues with leaks on valve or on valve body at install date or several years later. Also never seem to seize after months of not being used.

Clare Masse, Miller Plumbing and Electric, 14 Main Street, Zurich, Ontario

We work in some of the finest homes in Toronto, and so I don’t play games with quality. It’s dahl or nothing. dahl people are all about solutions – just like us. If I need a special, one of a kind valve, they’ll make it up on the spot and I’ll have it the next day. That’s why I’ve insisted on dahl products for over 40 years.

Mark Altman, M&T Mechanical, North York, Ontario
