In addition, the company is now responsible for drafting these standards such as the state standard GB/T “Steel Pressure Relief Valve for Petrochemical Industry”, “Dimension Confirmation, Type Selection and Installation of Pressure Relief Valve for Petrochemical Industry, Part One: Dimension Confirmation and Type Selection”, “Dimension Confirmation, Type Selection and Installation of Pressure Relief Valve for Petrochemical Industry, Part Two: Installation” and “Assessment for Resurfacing Welding Craftwork of Valve Facing”, etc..

The company pays high attention to development of new product and technical reform. The high temperature and pressure and temperature and pressure reducer of Generation II and temperature and pressure reducer of Generation IV, passed the appraisal of the provincial level in 2006, whose technical merit reach the domestic leading standard and obtain the provincial new product of Zhejiang Province and the high-tech product of Zhejiang Province in 2006. These products such as population parameter security valve, API526 security valve, high-handed warmer inlet and outlet value, rapid open-close valve and hydraulic pressure testing blocking valve passed the new product appraisal of the provincial level in September 2007, whose technical merits attained the advanced level of foreign products for the same kind, domestic leading level and domestic advanced level as well one after another. Such temperature and pressure reducers as high temperature and pressure, intermediate pressure and moderate high temperatures and pressures acquire in succession the Provincial and City-Level Prize for Progress in Science and Technology, and the security valve obtains the Ministerial Prize for Progress in Science and Technology, the Second Prize, and the clinker valve awards the Provincial and City-Level Prize for New Product and New Technology, and thermal control cabinet honors the Provincial and City-Level Prize for Progress in Science and Technology as well as that the air cannon block clearer obtains the City-Level Prize for Progress in Science and Technology. Presently, the company has eight patents of the state level, and the input for technical reform in recent three years is about RMB10 million yuan which enables to guarantee the stable improvement of product quality.

The company has the following leading products such as temperature and pressure reducer, security valve and power station valve, and in the meantime, which manufactures these general valves such as gate valve, disconnecting valve, oxygen disconnecting valve, bottom baiting valve, check valve, ball valve, butterfly valve, etc., as well as these pressure vessel products such as steam jet heat pump, air cannon block clearer, steam separator, steam manifold, etc.. The company has manufactured temperature and pressure reducers of more than 8000 sets with the top position of sales volume in the nation up to now. The security valve and power station valve, with fresh structure, reliable quality and stable performance, can be seen everywhere and are sold to these countries such as America, Canada, Brazil, Germany, Holland, Iran, India, Pakistan, Indonesia, South Africa, etc..
