Water Proportional Valve

Our water flow valve is an automatic device for the accurate measuring and regulation of watre flow,avoiding the weakness of traditional regulator by the combination of electronic technology and mechanical technology.  As a part of the digital control system, it features in compact size, steady work, accurate measurement, and stable work.
