Eclipse

The Halogen Valve Eclipse Actuator Emergency Shutoff System, designed for both 150-lb and 1 tonne gas cylinders, is an electrically driven actuator that acts directly on the cylinder valve stem.  The actuator mounts on the valve stem by means of a drive bushing and mounting clamp that secures to the yoke making it easy to remove during cylinder changes.  The actuator is designed to apply 50 ft-lb of closing torque to the valve stem after receiving an emergency shut down signal from any number of sources such as a chlorine gas detector.  The electronic circuit board within the control panel contains a microprocessor programmed to precisely control the valve closing cycle time and apply the required torque to the valve stem.  An uninterruptible 12 VDC battery power supply ensures operation even during loss of plant power.
