Zhejiang Zhongcheng Valve Co., Ltd. is a professional manufacturer of parallel slide valves, eject valves
and knife gate valves. Through years’ development and innovation, the company is now experienced in
manufacture and development, becoming a large-scale modern enterprise. Advanced management
system and production facility and well-organized, complete means of testing and inspection are the
assurance of top product quality. The company carries out production in strict accordance with GB in
China, API in US, and DIN in Germany. The knife gate valves, parallel slide valves, and eject valves
present a fine solution regarding abrasion resistance against solid, powder and sludge mediums in
such sectors including electricity generation, petrochemical industry, chemical industry, papermaking,
urban construction, sewage disposal, environmental protection, metallurgy, cement industry, etc.
company covers an area of more than 90,000 square meters a registered capital of 10.08 million yuan,
the staff 80 people, produces valves than 10,000 tons. After several decades of effort, the company has
formed a gate valve, ball valve, butterfly valve, globe valve, check valve, plug valves, control valves, etc. as
the leading valve product system, with a caliber up to 120 "and the pressure up to 4500LB, using the
temperature range of -196 ~ 750 °C, covering carbon steel, low carbon steel, stainless steel, duplex
stainless steel, high temperature alloys steel, MONEL, INCONEL, Hastelloy, titanium alloys and other
materials. The valve structure, performance, quality has reached the advanced level of similar products
at home and abroad, are widely recognized by domestic and international users.
Company's engineers and technicians of all types,20, can skillfully make use of CAD, three-dimensional
graphics and limited source of analysis, design software, and with domestic and international customers,
research institutes engaged in technical cooperation, the introduction and development of a number of new
products, obtain more patent certificate. In addition, the company also has first-class processing and testing
equipment, there are a variety of high-precision, large-scale machining center, CNC machine tools, and
specialty-specific equipment, such as horizontal machining center, machining center, gantry processing
center, large-scale Ball Lathe , horizontal boring and milling machine, etc.; equipped with PMI, tensile test,
impact test, metallurgical microscope and other materials testing equipment, r-Ray, ultrasound, magnetic
particle, liquid infiltration and other nondestructive testing methods, as well as three-dimensional measuring
instrument, low-temperature test, fire test, low-leakage test, vacuum test, and other special test equipment;
now under construction a valve cold and hot state test loop used to simulate the high and low temperature
operating conditions of the valves tested.
The company focus on the hardware infrastructure, while also focusing on quality management system and
product certification, issued by DNV have obtained ISO9001, ISO14000, ISO18000 certificate, and received the
