Ball valves are quarter-turn shut-off valves prized in plumbing for fast operation, long life, and a tight seal. A simple lever handle rotates a drilled ball to open or close flow, delivering low torque control and minimal pressure drop. That makes a ball valve a reliable choice for water supply lines, gas distribution, irrigation, hydronic heating, and compressed air systems.

You’ll find options for nearly any job: full-port ball valves for maximum flow, reduced-port models for compact spaces, and two-, three-piece, and union designs that simplify maintenance. Common materials include lead-free brass for potable water, stainless steel for corrosion resistance and higher temperatures, and PVC or CPVC for chemical compatibility and budget-friendly installs. Look for WOG ratings (e.g., 600 WOG) and temperature limits to match your application.

Connection types cover every plumbing scenario—threaded (NPT), sweat/solder, press, compression, PEX crimp/expansion, push-fit, and flanged. Features such as blowout-proof stems, PTFE seats, EPDM or FKM seals, lockable or tamper-resistant handles, and drain/bleed ports increase safety and serviceability.

Quick selection tips:
- Match valve size to pipe diameter; choose full-port for high-flow lines.
- Verify media compatibility and certifications (NSF/ANSI 61/372 for drinking water, CSA/UL listings for gas).
- Use gas-rated ball valves for fuel lines and lead-free brass for potable systems.
- Consider three-way ball valves for mixing or diverting circuits.

Installation and care are straightforward. Apply approved thread sealant or PTFE tape on threaded ends, avoid over‑torquing, support piping to prevent valve stress, and cycle the handle periodically to keep seats clean. For cold climates, protect from freezing. Replacement handles, stems, packing, and O-rings are widely available, making valve repair cost-effective.

Whether you need a brass ball valve for a home plumbing upgrade, a stainless steel ball valve for commercial service, or a PVC ball valve for irrigation, choosing the right specification ensures dependable shut-off, smooth flow, and fewer callbacks. Explore sizes from 1/4 inch to 4 inches and beyond to fit residential, commercial, and industrial needs.
