全启式安全阀概述：
上海好施阀门有限公司是国内生产安全阀的主导厂，厂内建有远东一流的安全阀测试中心，国产第一台安全阀就是我厂诞生的。二十多年来，好施牌安全阀的品种已发展到百余个系列，千余个规格，产品广泛应用于锅炉、石化、电站以及国防工业。并为国内第一座核电站秦山核电站研制成功了第一批核级安全阀。 好施牌安全阀主要产品系列分别荣获机械部信得过产品，上海市优质产品称号，国家银质奖。 好施牌安全阀是受压设备、容器或管路上的最佳超压保护装置。当设备压力升高达到预定值时，安全阀自动开启，继而全量排放，防止设备压力继续升高；当压力降低到规定值时，安全阀及时自动关闭。好施牌安全阀是选用者为保护工程设备安全运行的最理想的，最科学的明智选择。
