Fuzhou High and Middle Instrument Valve Co., Ltd., located at Economic Zone on the west coast of the Straits, the foot of Gushan of Fuzhou City, is an enterprise that scientifically researches and develops, manufactures and sells various high, middle and low pressure valves, which has passed ISO9001 Quality Management System Certification. The “Quanpai” high, middle and low pressure series valves, researched and produced by the company, was named among Top Ten Influential Brands in Chinese Valve Industry, and to the Key Supported Product List for Chinese Famous Brand Product. We are a factory in power plant fittings supply network of state power corporation and a member unit of Plumbing Branch Committee of China Construction Metal Structure Association. The product is a recommended product of Fujian Association of Plant Engineering. The main technical indexes of Pneumatic worm cut-off ball valve have reached the international advanced level, and won the Third Class Award of Fujian Province Science & Technology, the Second Class Award of Fuzhou City Science & Technology; furthermore, it was listed the National Key New Product Development Project. The pneumatic-hydraulic pressure balance globe valve was approved by the province, whose main technical indexes have achieved the world-class advanced level, listed 2002 National Key New Product Development Project. Besides, we are the first enterprise to manufacture the pneumatic four-way programmed valve that affiliated with SINOPEC Equipment exported Sudan and other countries. The pneumatic four-way programmed valve has earned the good reputation from the customer. Pneumatic high temperature ball valves have been used in the key project of Fujian Province— Meizhouwan chlorine-alkali project.
　　With rich production experience, strong technologies and a professional workers, the company has produced over many years thousands of various high, middle and low pneumatic worm cut-off ball valves, pneumatic four-way programmed valves, pneumatic O type cut-off ball valves, pneumatic gate valves, pneumatic-hydraulic pressure self-balancing cut-off valves, ball valves, cut-off valve, throttle valves, butterfly valves, gate valves, eccentric ball valves, etc. for petroleum, chemical, metallurgy, power, textile, machinery and other industries, and offered various soft sealing butterfly valves, soft sealing gate valves, anti-riot valves, water power control valve for construction department, installation department, municipal department, etc.
　　Main product features:
　　Pneumatic worm cut-off ball valve is a new automatic valve, with reasonable structure, light weight, quick on-off ( less than one second), flexible operation, long life ( more than 100,000 times), steady performance, high reliability, etc. especially used in flammable and explosive situation.
　　The pneumatic four-way programmed valve is the first china-made multifunctional valve used at a temperature of 250℃. It features the structure design with a temperature self-compensation function. Its sealing element is made from high temperature resistance, high temperature resistant materials so it has the reliable sealing and the long lifetime. It can network and be controlled remotely by a computer.
　　The dual four-way programmed valve, adopting the novel control style, can realize synchronous shift or reverse shift with one executor controlling two valves, simplifying the control program. It can network wand be controlled remotely by a computer.
tic O type ball valves are classified in two series: normal temperature and high temperature. Featuring its structure, the valve seat of high temperature ball valve is made from high temperature resistant material, used at a temperature up to 250℃. It is characterized by a temperature self-compensation function, reliable sealing and long lifetime. The actuator uses GTX series rack and pinion double-piston pneumatic actuator. This kind of valve is widely used for automatic control and long-distance control in petroleum industry, chemical industry and light industry, etc.　　
　　Soft sealing butterfly valve and soft sealing gate valve settle the drip, leakage and other problems in pipeline of construction, installation, municipal department, etc.
