Pneumatic 3 Piece Flanged Ball Valve

ALIS Valves offers Pneumatic 3 Piece Flanged Ball Valves designed for automated flow isolation in industrial piping systems. These valves feature a three-piece body construction that allows the central body section to be removed for inspection, cleaning and maintenance, depending on the design, while the pipeline connections can remain installed. The ball rotates through 90 degrees to open or close the flow passage, providing efficient on-off control. Flanged end connections allow secure bolted installation with compatible pipeline flanges, while the pneumatic actuator uses compressed air to operate the valve remotely. Depending on the application, these valves are available with stainless steel or carbon steel body options, suitable ball and seat materials, different pressure ratings, and double-acting or spring-return actuators to meet specified operating requirements.

Pneumatic 3 Piece Flanged Ball Valves are suitable for chemical processing, water treatment, oil and gas systems, power generation, pharmaceutical production and other industrial applications requiring automated flow control and convenient maintenance access. They can handle compatible liquids and gases within the valve’s specified pressure and temperature limits, subject to the selected body, seat and seal materials. Important selection factors include valve size, flange standard, pressure rating, operating temperature, process media, flow requirements, actuator torque and available compressed air pressure. Buyers should also verify the required control arrangement, operating frequency and fail-safe position, along with compatibility with the plant’s automation system. The three-piece construction can simplify servicing, while correct actuator sizing supports dependable operation under the specified differential pressure. Selecting the appropriate pneumatic 3 piece flanged ball valve helps provide reliable automated shut-off, easier maintenance and consistent performance in compatible industrial applications.
