中核苏阀
中核苏阀科技实业股份有限公司是经国家体改委体改生字199767号文批准，在对原苏阀厂进行股份制改组的基础上，由原苏阀厂独家发起而募集设立的。原苏阀厂创建于1952年7月导，1962年初成为部军工企业。
公司于一九九七年创立，是在承袭了中国核工业集团公司苏州阀门厂的主营业务、品牌、质保、技术和管理诸优势的基础上创立的上市股份公司，注册资本16800万元，是中国阀门行业和核工业系统的首家上市公司。
公司主厂房3672平方米，辅助厂房1530平方米，办公生活楼720平方米，设计能力年产核安全级阀门铸件及其它核工业阀门铸件1200吨。
苏阀地处长江三角地区，苏州是中国现代工业发展最迅速，工业基础最雄厚的地区之一，该地区企业集中工业门类齐全，配套能力强，同时也是人才重点流向区域，可以为苏阀今后做强做大提供人才、市场、管理、配套等多方面强有力的支持，苏阀从事了近五十年的阀门生产，在该领域已积累了丰富的生产组织和管理的能力，经营管理层的知识化、年轻化也是企业寻求大发展，为企业开拓进取宏观决策提供了必要的保证。公司“退城进区”和中核总公司控股重组后所带来的广阔前景是苏阀重新焕发生机的重大机会，充裕的资金可以使生产设备更新和增加，引进功能更强大齐全的装备为生产增添后劲。技术设计2005年，技术研发中心经苏州市科技局批准，正式成立中核科技阀门工程技术研发中心。2006年12月经江苏省科技厅批准, 成立了江苏省特种阀门工程技术研究中心。
