Ball Valves

Quarter-turn ball valves provide tight shutoff for water, air and process lines in installs and MRO.

For plant and utility service, choose industrial ball valves with full port designs and resilient seats for smooth flow and long life.

Jomar, Midland Industries, Legris and Midwest Control cover common sizes, thread types and pressure ranges for new work and replacements.

For domestic service, select ball valves for water in lead-free brass with easy quarter turn handles.

Frequently Asked Questions

What is a ball valve and how does it work?

Inside, a drilled sphere turns one quarter turn. Inline the port passes flow; turned sideways the seats stop it. For shutdowns, manual ball valves close fast and add very little pressure drop.

How do I choose the right size and material for a ball valve?

Size the bore to match the pipe. Use full port when minimal restriction matters. Brass fittings suits potable lines, stainless for corrosives, PVC for cold compatible media. For drinking service, choose lead-free ball valves for water.

Where are ball valves commonly used in plumbing systems?

Common locations include the main shutoff, water-heater hookups, fixture stops, branch isolators, irrigation runs, and pump connections. Ball valves give quick, dependable isolation on hot and cold lines.
