The Italian AIRTORQUE AT251S12A pneumatic ball valve is composed of an XSTOU ball valve paired with an AIRTORQUE AT series actuator mechanism. It features strong functionality, compact size, lightweight design, reliable performance, simple integration, and high flow capacity. This valve is particularly suitable for applications involving viscous media, particles, or fibrous substances. Currently, this electric control butterfly valve is widely used in industrial automation systems across various sectors, including food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and research equipment, and power generation.

The Italian AIRTORQUE AT251S12A pneumatic ball valve combines a ball valve with a pneumatic actuator. The pneumatic actuator operates relatively quickly, with the fastest switching speed reaching 0.05 seconds per cycle, hence it is often referred to as a pneumatic quick-cutoff ball valve. Pneumatic ball valves are typically equipped with various accessories, such as solenoid valves, air treatment triple units, limit switches, positioners, and control boxes, to enable local control and remote centralized control. This allows valve switching to be managed from the control room, eliminating the need for manual operation on-site, at heights, or in hazardous areas, thereby significantly saving human resources, time, and enhancing safety. Specific classifications of pneumatic ball valves include: stainless steel pneumatic ball valves, plastic pneumatic ball valves, sanitary-grade pneumatic ball valves, carbon steel pneumatic ball valves, two-way pneumatic ball valves, three-way pneumatic ball valves, and four-way pneumatic ball valves.
