H71H-16Q不锈钢对夹式止回阀本阀门由于阀体、阀瓣、阀盖等组成阀瓣就在液压力和弹簧力的作用下关闭制止了流体的返流H71H-16P对夹316止回阀H71W-16R对夹316止回阀H71H-16Q对夹316止回阀H71X-16R对夹316止回阀H71H-16P对夹316止回阀H71W-25R对夹316止回阀H71W-25P对夹316止回阀H71H-25P对夹316止回阀H71W-25P对夹316止回阀H71H-16R对夹316止回阀H71H-16P对夹316止回阀H71H-25C对夹316止回阀H71W-16R对夹316止回阀H71W-16P对夹316止回阀H71W-25R对夹316止回阀H71W-16R对夹316止回阀H71H-40P对夹316止回阀H71H-64P对夹316止回阀H71W对夹316止回阀H71H-16C对夹316止回阀H71H-64P对夹316止回阀H71H-40P对夹316止回阀H71W对夹316止回阀
该阀由阀体、阀瓣、弹簧等组成,水平或垂直安装于管路系统,防止介质倒流,具有结构短、体积小、质量轻;阀瓣关闭快速,水锤压力小;流道通畅,流体阻力小;动作灵敏,密封性能好。
