Pneumatic 3 PC Screwed Ball Valve

ALIS Valves offers Pneumatic 3 PC Screwed Ball Valves designed for automated flow isolation in industrial piping systems. These valves feature a three-piece body construction that allows the central valve section to be removed for inspection, cleaning and maintenance, depending on the design. A spherical ball with a central bore rotates approximately 90 degrees to open or close the flow passage, providing efficient on-off control. Screwed or threaded end connections allow installation with compatible pipeline fittings, while the pneumatic actuator uses compressed air for remote operation and integration with automated control systems. Depending on the application, these valves are available with stainless steel or other suitable body materials, different seat and seal options, and double-acting or spring-return actuators to meet specified operating requirements.

Pneumatic 3 PC Screwed Ball Valves are suitable for chemical processing, water treatment, manufacturing equipment, compressed air systems, industrial utilities and other applications requiring automated flow control and convenient maintenance access. Depending on the valve construction and material selection, they can handle compatible liquids and gases within their rated pressure and temperature limits. Important selection factors include valve size, thread standard, body material, operating pressure, temperature range, process media, seat compatibility and actuator torque. Buyers should also consider the compressed air supply pressure, operating frequency, control arrangement and required fail-safe position. Threaded connections must match the pipeline fitting standard and be suitable for the intended pressure and sealing requirements. Correct actuator sizing and proper installation help support reliable operation and effective shut-off. Selecting the appropriate pneumatic 3 PC screwed ball valve helps provide automated flow isolation, easier maintenance and dependable performance in compatible industrial applications.
