MSS SP-71 Class 125 Cast Iron Air Cushion Swing Check Valve

Product Description

Why to add this cylinder?

With an external cylinder, when the valve disc quickly closes but there is still 30% left to close, the cylinder begins to work, causing the valve plate to slowly close. This can prevent the medium in the pipeline from quickly accumulating pressure and damaging the pipeline system

Why to add the weight block?

Equipped with a weight block, it can quickly close in the pipeline and eliminate destructive water hammer
