About Ball Valves

Ball valves are one of the most reliable and widely used shut-off solutions in plumbing systems. Designed for quick operation, durability, and long-term performance, a ball valve uses a quarter-turn mechanism to instantly control water flow. Whether in residential plumbing, commercial construction, or industrial systems, ball valves provide dependable performance even after long periods without operation—making them a preferred choice among professional plumbers and DIY installers.

At Plumbingsell, we supply a range of plumbing ball valves, including lead-free brass, PVC and CPVC, PEX-ready, and multi-port configurations—compatible with various pipe types such as PEX, copper, PVC, CPVC, and plastic pipe connectors.

What Is a Ball Valve?

A ball valve is a quarter-turn shut-off valve featuring a precision-machined, spherical ball inside the valve housing. The ball contains a bore that allows or blocks water flow depending on the handle position:

• Open Position — The opening aligns with the pipe for full, unobstructed flow
• Closed Position — The ball turns 90 degrees, sealing the passage and creating a leak-resistant seal

This mechanism makes ball valves ideal for use as water valves, waterline valves, shutoff valves, emergency plumbing shut-offs, and appliance isolation valves. With clear open/closed visibility, ball valves simplify system diagnostics and maintenance, even for non-professionals.

Types of Ball Valves

Ball valves can be categorized by port type, application, material, and connection method. Common types offered at Plumbingsell include:

• By Port Type:
  • Full Port (Full Bore) — Maximum flow with minimal pressure drop, ideal for water supply and HVAC systems
  • Standard Port — Compact design where slight flow restriction is acceptable
• By Application:
  • 2-Way Ball Valves — Simple ON/OFF shut-off control, most commonly used
  • 3-Way Ball Valves (L-Port or T-Port) — Used for diverting, mixing, or complex flow control
• By Material:
  • Lead-Free Brass Ball Valves — Safe for drinking water
  • Bronze
  • PVC / CPVC Ball Valves
  • Stainless Steel Valves — Ideal for high-pressure, industrial, or corrosive environments
• By Connection Method:
  • Threaded (NPT / FIP / MIP) — Standard household shut-off valves
  • Sweat (Copper) — Traditional copper pipe plumbing lines
  • PEX (Crimp or Expansion) — Modern residential water line installations
  • Push-to-Connect — Tool-free installation for quick retrofits
  • Compression — Commonly used for fixture connection points like faucets or toilets

Where Are Ball Valves Used?

Ball valves are commonly installed in residential and commercial plumbing systems, including:

• Main water shutoff points
• Water heater isolation
• Sink, toilet, dishwasher, and washing machine supply lines
• Irrigation and outdoor hose systems
• Hydronic and HVAC loops

Because they operate reliably even after long inactivity, ball valves are preferred over gate valves and globe valves for primary shut-off functions.
