China Outong Group Zhejiang Petrochemical Valve Co., Ltd. was founded in 1978. The company currently has 2 valve manufacturing bases, located at No. 518, No. 3rd Road and No. 6, Binhai Park, Wenzhou Economic and Technological Development Zone, Binhai, Donghai, and No. 397, Road 6, respectively. The two valves are about 8 kilometers apart. The company has two casting bases and one blank treatment and storage base. The cumulative area of ​​the casting base is 110 mu. It also has fine casting and sand casting process castings, and the materials include carbon steel, stainless steel, chromium molybdenum steel, alloy steel, etc. The blank treatment and storage base reaches 40 mu, meeting the needs of batch casting processing, storage and testing.

The company has a registered capital of 160 million yuan, covering a total area of ​​120 mu (excluding casting), a construction area of ​​125,500 square meters, 362 processing and testing equipment (sets), and currently has 368 employees, including 92 engineering and technical personnel. In 2015, the valve output value was 420 million yuan, sales revenue was 360 million yuan, and profit and tax revenue was 29 million yuan.

The company mainly produces gate valves, stop valves, check valves, ball valves, butterfly valves, low temperature valves, hydrogen valves, oxygen valves, open metal seal valves, high temperature blending valves, and plugs. There are more than ten major categories, including valves, flat gate valves, power station valves, instrument valves, oil well devices, insulation jacket valves, bellows valves, etc., with a total of more than 6,000 models and specifications. The valve body materials are made of carbon steel, stainless steel, alloy steel, ultra-low carbon stainless steel, titanium alloy, high-nickel alloy and Monel alloy; the driving methods include manual, gear transmission, electric, pneumatic and hydraulic.
