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

American Petroleum Institute API6A, API6D, Lloyd's Register of API607 , the French classification society of

the CE / PED and the National Nuclear Security Administration's nuclear pressure equipment design and

manufacturing licenses, as well as national pressure piping components, the security certificate of registration (AZ).

When facing both opportunities and challenges in this new century, Zhongcheng is providing satisfying

products with top class quality and services. We sincerely welcome friends from home and abroad for

business discussion and for a brilliant future jointly.
