1/2 inch ball valve /floot valve

Product Description

The 1/2 inch ball valve is a quarter-turn shutoff valve. It provides reliable on/off control for liquids and gases in residential, commercial, and industrial applications.

This valve features a durable brass body with a chrome-plated ball and PTFE seats. It offers excellent corrosion resistance and a long service life.

The simple quarter-turn operation allows for fast, intuitive control. When the handle is parallel to the pipe, the valve is open. When perpendicular, it is closed.

Whether you need to isolate a water line for fixture repair or shut off a gas line in an emergency, this valve delivers dependable performance.

How Does a 1/2 Inch Ball Valve Work?

A common question is how the valve achieves such reliable sealing.

Inside the valve, a spherical ball with a hole through its center sits between two PTFE seats. When the handle is turned, the ball rotates.

When the hole aligns with the pipe, the valve is open, allowing full flow. When the ball rotates 90 degrees, the solid faces block the pipe. This creates a positive, bubble-tight shut-off.

This simple yet effective mechanism makes the ball valve one of the most reliable shutoff devices available.

What Are the Key Features of This 1/2 Inch Ball Valve?

The 1/2 inch ball valve is engineered with several features for reliable performance.

The full-port design provides unrestricted flow. This minimizes pressure drop across the valve. PTFE seats offer low operating torque and excellent chemical resistance.

The blowout-proof stem ensures safety under pressure. The lever handle requires only a quarter turn to operate. Many models include a locking device for safety.

What Types of 1/2 Inch Ball Valves Are Available?

The 1/2 inch ball valve is available in several configurations.

Two-piece ball valves offer a good balance of cost and serviceability. Three-piece ball valves allow in-line maintenance. The center section can be removed without disturbing the piping.

Floating ball designs are standard for 1/2 inch ball valves. The ball floats downstream to create a seal. Full port valves have the same internal diameter as the pipe, maximizing flow capacity.

How Do You Install a 1/2 Inch Ball Valve?

Proper installation ensures optimal performance. The valve features standard 1/2 inch female threaded connections.

Apply PTFE tape or pipe joint compound to the male threads of your pipe. Hand-tighten the valve onto the pipe. Then use wrenches to tighten firmly, typically one to two turns past hand-tight.

Avoid over-tightening, which could damage the threads or valve body. Always verify the valve is installed with flow in the correct direction if an arrow is marked.

What Are the Pressure and Temperature Ratings?

The 1/2 inch ball valve is rated for various pressures depending on material.

Brass valves typically carry a 600 WOG rating. This is suitable for pressures up to 600 PSI for water, oil, or gas. Some stainless steel valves are rated up to 1000 WOG or higher.

The maximum temperature rating is typically 450°F.

What Materials Are Available for 1/2 Inch Ball Valves?

The 1/2 inch ball valve is available in various materials to suit different applications.

Brass offers excellent corrosion resistance for water, oil, and gas applications. Stainless steel provides superior durability and corrosion resistance for harsh environments. It is available in 316 stainless steel for marine or chemical service.

PVC valves are lightweight and corrosion-resistant. They are ideal for chemical applications.
