The APL Series Limit Switch Box is a compact, weather proof enclosure with internal adjustable position switches and an external visual indication. It has NAMUR standard mounting and drive, and is ideally suited for mounting on to quarter turn actuators and valves.
As a major part of automation control system, KH series manual override is widely used with pneumatic actuators in combination.It’s mainly used for 90°rotary ON/OFF valve,such as butterfly valve,ball valve,plug valve.The manual override make it possible to manual operation when the pipeline is air failure.
Mounting base standard:ISO5211
