全啟式安全閥概述：
上海好施閥門有限公司是國內生產安全閥的主導廠，廠內建有遠東一流的安全閥測試中心，國產第一臺安全閥就是我廠誕生的。二十多年來，好施牌安全閥的品種已發展到百余個系列，千余個規格，產品廣泛應用于鍋爐、石化、電站以及國防工業。并為國內第一座核電站秦山核電站研制成功了第一批核級安全閥。 好施牌安全閥主要產品系列分別榮獲機械部信得過產品，上海市優質產品稱號，國家銀質獎。 好施牌安全閥是受壓設備、容器或管路上的最佳超壓保護裝置。當設備壓力升高達到預定值時，安全閥自動開啟，繼而全量排放，防止設備壓力繼續升高；當壓力降低到規定值時，安全閥及時自動關閉。好施牌安全閥是選用者為保護工程設備安全運行的最理想的，最科學的明智選擇。
