Piston flow control valve product overview

Piston flow control valve is the technical staff of the Company in Germany, Japan, advanced experience, summed up the domestic design and manufacturing and practical experience, based on the characteristics of fluid mechanics and developed the pressure regulating valve. Has been in power plants, water diversion, water and other fields has been widely used. This series of improved flow control valve not only applies to clean water, natural rivers and lakes for water, light sewage has a good tolerance. From the design structure and material selection to solve the flow control valve over the years easy scaling, jamming, driving the device is too large problem.
