Description of double seat control valve 

It adopts double guide structure. The valve body is compact, and the flow direction is S-streamlined, this valve  pressure drop loss is small and flow rate is large,  flow characteristic precision is high. Due to the valve core is fixed at the top of the guide , the characteristics is strong seismic resistance
