EMERGENCY VALVE SHUTOFF SYSTEMS for CHLORINE, SO2, AMMONIA & OTHER GASES Halogen Valve Systems is the leading manufacturer of electronically actuated emergency valve shutoff systems for chlorine and sulfur dioxide 150 lb cylinders and ton containers. If you feed Chlorine, Sulfur Dioxide, Ammonia or other potentially dangerous gases from cylinders or ton containers, Halogens Emergency Valve Shutoff Systems can provide you with a critical extra measure of safety. Do not let a gas leak become a reportable Hazmat incident. Stop a leak within seconds of detection by automatically closing the ton container or cylinder valve. Halogens actuators quickly mount to cylinder valves without the use of any tools, and still allow the valve to be manually opened or closed while the actuator is in place. Halogen Valve Systems are the only shutoff systems that confirm that the valve was torqued closed to the Institute recommended standard, and all Fire Codes recognize and approve the shutoff system as an alternate to a scrubber. Without an automatic valve shutoff system, dealing with a leak means cleaning up the mess after the incident. Our fully automated and microprocessor controlled systems can respond to a leak immediately and your operational personnel don't have to risk exposure during a gas leak. Protect your personnel and environment. Visit www.halogenvalve.com and see how Halogen's Emergency Valve Shutoff Systems can increase the level of safety in your plant.
