AIRA APL/1008 Pneumatic Actuated Wafer Butterfly Valve
Namokar Enterprises – Dealer & Supplier of AIRA Pneumatic Butterfly Valves
The AIRA APL/1008 Pneumatic Rotary Actuator Operated Wafer Type Butterfly Valve is a compact quarter-turn automated valve designed for reliable ON/OFF and flow-isolation applications. It combines a rubber-lined concentric butterfly valve with a pneumatic rotary actuator, making it suitable for HVAC, chilled water, water treatment, utility lines, industrial process systems and general fluid-control applications.
The APL/1008 catalogue specifies a centric-disc butterfly valve with a single-piece rubber-lined body, short wafer construction and pneumatic rack-and-pinion actuation.
