Pneumatic Aluminum Butterfly Valve

ALIS Valves offers Pneumatic Aluminum Butterfly Valves designed for automated flow isolation and control in compatible industrial piping systems. These valves feature a lightweight aluminum body or aluminum actuator housing, depending on the design, along with a rotating disc that turns approximately 90 degrees to open or close the flow passage. A pneumatic actuator uses compressed air to operate the valve, enabling remote control and integration with automated process systems. Aluminum construction can reduce overall equipment weight and provide useful corrosion resistance in suitable environments, while the disc, seat and sealing materials are selected according to the process media and operating requirements. Depending on the configuration, these valves may be available in wafer or lug-style designs, with double-acting or spring-return actuators for different operating and control needs.

Pneumatic Aluminum Butterfly Valves are suitable for applications in water treatment, HVAC systems, industrial utilities, ventilation systems and compatible fluid handling processes. Their suitability depends on the actual body construction, wetted materials, operating pressure, temperature and process media. Important selection factors include valve size, connection type, pressure rating, disc and seat materials, flow requirements, compressed air supply pressure and actuator torque. Buyers should confirm whether the aluminum is part of the pressure-containing valve body or only the actuator housing, as these constructions have different performance characteristics. The required control arrangement, operating frequency and fail-safe position should also be considered when integrating the valve into an automated system. Selecting the appropriate pneumatic aluminum butterfly valve helps provide lightweight construction, convenient automation and dependable flow control within the specified operating limits.
