• Major 1″ brass ball valve.
• 1″ suits riser and branch isolation rather than individual fixtures.
• Quarter-turn lever gives immediate, unambiguous shut-off.
• Full-bore design passes near-full flow when open.
• Brass body and ball resist corrosion and long-term seizing.
• Choose 1/2″ or 3/4″ for fixtures, 1 1/2″ and above for mains.
