SENTRY GS for Gas Service Lines
Gas utilities use SENTRY GS excess flow valves as a preventive measure to reduce the possibility of damage or injury in the case of a break in the gas service line. It's recommended that excess flow valves be installed in the branch line off the main gas line and in the gas service line.
SENTRY GS excess flow valves have been used effectively for more than 20 years in underground gas service lines throughout the world. In Gemany alone, more than 1,000,000 Mertik Maxitrol excess flow valves (underground and residential) are currently in service. Mertik Maxitrol offers a complete range of excess flow valves from DN15 to DN50 for different operating pressure ranges.
