NPT Ball Valves (Various Sizes)

NPT ball valves are flow control devices featuring a ball with a hole through its center and a threaded National Pipe Taper (NPT) fitting for connecting to pipe systems. NPT threads are a US standard for tapered threads used on threaded pipes and fittings, designed to create a more reliable seal for carrying liquids and gases. The "ball" in NPT ball valves refers to the internal mechanism – a spherical closure unit that allows for the control of flow.

These valves are commonly employed in various applications, such as water, natural gas, and compressed air systems, due to their durability and the tight seal formed when the ball is in the closed position. In particular, brass-body NPT ball valves are often used in home water and natural gas piping systems because they work well with oil, water, and compressed air. The brass body typically houses a chrome-plated ball and a quarter-turn handle, and Teflon seals are incorporated to ensure tight sealing and ease of operation.

NPT ball valves are versatile and used across many industries for their reliable fluid control and efficient design. They are particularly advantageous in applications requiring robust seals under pressure and are capable of being quickly opened or closed with minimal effort.
