Process Ball Valves

Process ball valves are typically installed in shutoff valves and are often controlled with a lever or handle. The valve contains a ball with a hole through it. The hole aligns with the pipes when the valve is open, allowing flow. When the valve is closed, the hole rotates perpendicular to it, shutting off the flow.

What are process ball valves used for?

Process ball valves are commonly used for isolating fluids in applications involving instrumentation and processes, such as the distribution of natural gas. They come in a range of attachment types and pressure ratings.

Process ball valves are durable, performing well after many cycles. They're also reliable, closing securely even after long periods of disuse. These qualities make them ideal for shutoff and control applications. As a result of their versatility and ease of operation and repair, they're extensively used across industry.

Types of process ball valves

Process ball valves are distinguished by their attachment types, which include compression and threaded. The valve bodies can be made from brass, nickel-plated brass, PVC, PVDF or stainless steel. Balls can be made from brass, chrome-plated brass, nickel-plated brass or stainless steel.
