Pneumatic Linear Diaphragm Actuator

Pneumatic Linear Diaphragm Actuator

“AIRA” offers an environmentally friendly flow-control solution for steam lines through its Forged Ball Valve range. Designed for high-performance in demanding conditions, the valve ensures bubble-tight shutoff and optimal process steam conservation—outperforming conventional multi-turn rising stem valves. With pressure handling capabilities of 103 bar at 38°C and 5 bar at 270°C, this quarter-turn valve is ideal for quick-close operations and is easily automated.
