ZCRB gas emergency shut-off valve DN25-300MM

Usage ZCR family is supporting the safety devices installed on new gas pipeline project, the main application is as follows: 1, and combustible gas leak detection equipment is connected. When the instrument detects combustible gas leak, automatically and quickly closed the main supply gas valve, cutting off the supply of gas, time to stop the occurrence of fatal accidents. 2, and thermal equipment limit temperature (or pressure) is connected to the safety controller. When the limit value within the device detects temperature or pressure exceeds the set automatically and quickly turn off the gas supply valve to stop the supply of fuel. 3, with high-rise buildings connected to the central fire alarm system. When the building crisis situation occurs, automatically cut off the gas supply inside the building, to prevent the gas explosion occurred. 4. Set ZCR gas plant within the city or the gas supply pipe network emergency shut-off valve, in the central control room centralized control, long-distance remote control, emergency shutdown supply pipeline accident scene.
