进口气动高性能偏芯蝶阀 美国RETZ瑞茨

　　RETZ/我们一直致力于流体控制领域的持续创新，始于2005……

　　高性能蝶阀采用双偏心结构设计。阀轴双偏离阀体结构中心，同时结合阀板圆弧密封面设计，使阀板在打开时迅速脱离密封座，以减小密封面的摩擦力，阀板在关闭时具有良好的密封性能。中心自定位密封阀座结构设计结合独特的阀座补偿密封设计，使阀座密封得到有效补偿的同时减少开启、关闭时的摩擦力，大大减小阀门的操作力，有效提高了蝶阀的控制准确度。该系列蝶阀密封性能稳定可靠，使用寿命长。适用于一般腐蚀性气体，液体介质的调节和切断使用 Thehigh-performance butterfly valve adopts a double eccentric structure design.The valve shaft deviates from the center of the valve body structure, andcombined with the arc sealing surface design of the valve plate, the valveplate quickly detaches from the sealing seat when opened to reduce the frictionof the sealing surface. The valve plate has good sealing performance whenclosed. The center self positioning sealing valve seat structure designcombined with unique valve seat compensation sealing design effectivelycompensates for valve seat sealing while reducing friction during opening andclosing, greatly reducing the operating force of the valve and effectivelyimproving the control accuracy of the butterfly valve. This series of butterflyvalves has stable and reliable sealing performance and long service life.Suitable for regulating and cutting off general corrosive gases and liquidmedia.
