Wafer Type Dual Disc Check Valve
产品特性/Product Feature
■ 中线结构,结构长度短,体积小,重量轻。
■ 流道通畅,流体阻力小。
■ 阀瓣采用弹簧加载,其快速关闭能有够效减小水锤压力。
■ 密封性能好,关闭无噪声,可以满足零泄漏要求。
■ 安装方便,水平管道和垂直管道都可以使用。
■ Centerline structure, short face to face length, small volume and light weight.
■ Unobstructed flow passage, small fluid resistance.
■ Disc uses the spring to load, its quick closedown can effective reduce the hammer pressure.
■ The sealing property is good, the closure does not have noise and can meet the requirement of zero leakage.
■ Easy installation, can be used in both horizontal and vertical pipes.
