Ball valves are not limited to on/off applications; for basic flow control a ball valve can be sufficient depending on your application.  The flanged ball valve is equipped with an explosion proof PEX01 4-20mA positioner, lock-up valve, filter regulator and SS tubing.  During normal operation, the ball valve is controlled by the 4-20mA signal (4mA being fully closed, 20mA fully open).  When air supply is lost, the lock-up valve is triggered to close and blocks all of the actuator air ports, locking the valve in position.  This is known as “fail-freeze”.  Max-Air can configure a control valve assembly for your specific needs, give us a call and see what we can do!
