Product details

1. overview of Pneumatic nylon clamp butterfly valve products:

Pneumatic nylon clamp butterfly valve with two gaskets plus a pair of open ring and spring clamp structure, to prevent the valve stem inadvertently disassembled while bearing a certain amount of axial force, to prevent the weight of the valve stem transferred to the butterfly plate.O - ring of nitrile rubber effectively prevents impurities from invading and strengthens stem seal to prevent medium from flowing out.Single integral valve shaft without pin flat key drive, so that the medium and metal (valve shaft and valve body) completely isolated to eliminate internal leakage and corrosion.Pin free double D flat key connection ensures a rigid drive and reliable two-way seal, allowing the valve plate to move up and down left and right freely in the center, greatly reducing seat stress and wear, effectively extending seat life.
