Pipe valve is mainly used force automation to centrifugal, mixed flow and axial pumps water pipes and drainage pumping station, the design of two piston and diaphragm control device, can be separately applied to water, raw water and wastewater medium class, slag Whey class media; by accessories, real-time feedback line valve operation, distance transportation engineering, automatic control and remote detection; on the type of product, the company developed a common type, backwater low pressure type, water type, five specifications, to meet different customer needs different conditions. Due to the compact structure, small size, light weight, especially for large diameter piping systems. It can be widely used in electric power, environmental protection, metallurgy, petrochemical, water department, municipal, food industry supply and drainage systems, sewage pumping stations, and other chemical fluid delivery system, is the current domestic and international structure of the most innovative, the most advanced performance, run the most Reliable Pumping new control equipment.
