Nanjing, Suzhou Valve Co., Ltd. is a valve development, design, sales of high-tech enterprises. Main products: valves, pneumatic valves, electric valves, butterfly valves, ball valves, solenoid valves, lined valves and other general-purpose valves and other products. Widely used in metallurgy, refining, petrochemical, oil, electricity, building automation, paper printing, biotechnology, food and other industries, welcomed by users and praise. High-performance pneumatic valve, high pressure valve, pneumatic cut off valve, control valve, CV3000 pneumatic control valve, sleeve valve, the electric control valve sleeve, imported electric adjustment, fine small pneumatic control valve, self-operated control valve, electric ⒈ three-way valves by eliminating the need for system debugging, so save a lot of trouble, saving a lot of time and shorten the completion date; ⒉ because they are not using a valve block and a hierarchical control valves, so the more you save pipes, insulation materials and installation costs and time; ⒊ at all times so that the water system is in equilibrium, so no matter stage construction or equipment installation stages will not affect the balance of the water system ⒋ or even after the project is put into operation due to late. change certain purposes need to change the water system in some areas, will not affect the water system in other regions, but will not affect the balance of water systems in other regions. ⒌ Since the entire system is in dynamic equilibrium, so the refrigeration unit and pump will be the most energy-efficient state operation, saving a lot of maintenance costs. ⒍ Since the flow balance system is automatic, so installation and maintenance more convenient, and eliminate human error . undermine the balance valve according to the stroke characteristics can be divided into: linear and rotary. Straight trip includes: single-seat valve, double seat valves, sleeve valves, angle valve, three-way valves, diaphragm valves; angle Highlights include: butterfly valves, ball valves, eccentric rotary valve, full-function ultra-light control valve. Valve drive can be divided by: pneumatic control valve, the electric control valve and hydraulic control valve; press regulator can be divided into: regulated, cut-off, adjust the cut-off; according to the flow characteristics can be divided into: linear, equal percentage , parabola, quick open. Regulating valve for air, water, steam, corrosive media, mud, oil and other media. Pneumatic transmitters and regulators appear, it will inevitably lead to the application of gas verb section of the valve. After the valve or valve Pressure regulator they are essentially in favor of the instrument air instead of fluid the process. Many production companies have developed into a valve regulating valve manufacturer. Regulating valve from the quantity and complexity continue to develop, many improvements valve body and attachments can be used to solve a variety of problems. The intent of this manual is to make the project are familiar knot dissipation and factors regulating valves, instrumentation engineers to help in the application choose the best valve, actuator and accessories. http://www.szngvalve.cn
