NSEN valve dispatched a batch of PN40 Valve to Russia

The size is DN300 and DN600

Body: SS321

Disc: SS321

Metal seated

Uni-directional sealing

On the premise of ensuring the thickness and strength of the disc, we adopt the design of the upper and lower valve stems, which can greatly reduce the flow resistance and increase the flow capacity of the medium

When the pressure reaches PN63, PN100, the advantages of the upper and lower valve stem design are particularly obvious
