What makes it practical
Choosing the B&K ProLine 1-1/2 in. Brass Sweat Ball Valve Full Port Lever means you’re equipping your system with a valve that prioritizes flow efficiency, durability, and ease of use. The full-port bore reduces turbulence and ensures a steady supply downstream, while the lever handle enables fast shutoff without fumbling with turns or knobs. The chrome-plated brass surface resists corrosion and stands up to the heat and moisture typical of domestic water systems.
Installation and care tips
Designed for copper sweating, this valve should be installed on cleaned, primed copper tubing. Apply appropriate flux and a steady, controlled heat to create a solid solder joint, then allow joints to cool before testing for leaks. Avoid overtightening fittings and periodically inspect the joints and lever for smooth operation. With proper installation, this valve delivers reliable service and easy future maintenance.
