The Terminator Actuator from Halogen Valve Systems can be used on chlorine ton containers and 150-pound cylinders to instantly stop the flow of chlorine in case of an emergency. The clamp-mount version incorporates the same mounting clamp design as the Eclipse Actuator, allowing it to be quickly and securely installed on ton container valves without the use of any tools. It can be used on containers feeding through a pressure manifold, or can be installed side by side with tank-mounted vacuum regulators. Its Gemini controller provides DC power and control to one or two units and can be combined for systems with larger quantities of containers. 949/261-5030; www.halogenvalve.com
