Its industrial park occupies an area of 18000 sq.meters, of which, the building area is over 13500 sq. meters, the fixed asset reaches 50 million RMB. Thecompany has 300 equipments such as modern machinery processing center, digital control machina tool,and general machine tool etc. and has the oversize vertical machine tool with 3.5 meters processing diam-eters, and has some special equipments for metal material physics and chemistry test, mechanical perform ance dynam test, ultrasonic thickness test, rigidity test, non-breaking detecting,plasma repair welding,metal hot-treatment, safety valve hot-state, cold-state full-performance test center, spring strength test etc.

The company is one member of China Current Mechanical Valve Association, the production unitappointed by China Chemical Industry Equipment Head-office, Huge dragon in county business enterpriseandone if 20 top enterprises in Chinese Pump & Valve Land, and the enterprise permitted to produce safety valve by State Mechanical Industry Ministry. Its products respectively passed the AZ certification of State Technology Supervision Bureau, CE certification of E.E.C. Pressure Equipment PED and API certification of USA Oil Association.

The company produces ten more kinds of products such as safety valve, butterfly valve, ball valve,gate valve, stop valve, and non-standard valve etc, the specification of products is over 2000 kinds. Andmay design and manufacture products according to the standards of ANSI, API, DIN, BS, JIS and GB,The valves are mainly made by these materials such as WCB,WC1,WC6,WC9,ZGCr5Mo,ZG15Cr1Mo1V,CF8,CF8M,CF3,CF3M,12CrMoV,ZG1Cr18Ni9Ti, and ZG1Cr18Ni12Mo2Ti etc, its drive means coverthe manual, worm wheel transmission, electric, pneumatic, liquid drive, and electric & liquid linkage etc.the normal pipe diameter is from DN10~3000 to 1/2~40, the work pressure is from 0.6~42.0MPa to 150Lb~2500Lb, the work temperature is from -196℃~700℃. The products are widely applied in these industries of power station, boiler, oil, chemical industry, city construction, medicine, chemical fertilizer,metallurgy, and mining etc. a part of products have replaced imported products to be used on key equipm-ents in State Important Engineering Projects.

The company is always insisting on the tenet of Existing by quality and Developing by technology.Its products passed ISO9001 international quality system certification in 1998. Now the company has dev-eloped into a high & new technology enterprise gathering industrial valves'study, development, manufact-ure, test and selling. The company now has 40 more senior and intermediate technicians which are engaged in the valve's design, craft, test and service. The company established CAD work site, CAAP development center and after-sales service center, by which to make dynamic and simulation design at products and in order to ensure the fulfillment of rigorous work.

The company brought in new concept of valve manufacture, namely, the high flexibility, complex and precise at production course and the network, information and intelligentizing at manufacture and management. The company consists of two parts, namely, the production equipment (hard ware estab-lishment) ard company's management software. The company set up the valve production lines, paintingwork line, assembly work line, and full-automatic solid storehouse etc. The company implemented the management ofcomputer network,information and intelligentizing at all operations such as selling (before-sales and aftersales service), production, technology, finance, and personnel etc. thus it may also be named an intelligentizing network valve factory. every part of factory is covered by computer network,which structures a huge information nerve system, thus offers reliable and effective means for the command of instruction and timely feedback of information. The whole production and management is the perfect combination of modern informaion technology (IT) and traditional manufacture technology (MT), and offers you the network, inform ation and intelligentizing industrial valves.

Yongyi valve shares the technology of new century together with you, and lets you feel the top manufacture technology of world at hand.
