Wafer butterfly valves, both classes.

Ductile iron body, EPDM seat, SS304 disc. DN50 to DN1200. One body, two pressure classes — PN10 and PN16 differ only in disc thickness. Dispatch 7–15 days from Tianjin.

One body, two classes

PN10 and PN16 use the same ductile iron body, seat and lever — only the disc is thicker for the higher class. The DN is cast into the body, so a mix-up at site is hard to miss.

Stacked wafer butterfly valves in the assembly hall

Assembly hall · Tianjin

Finished valves in the yard, waiting on a packing list. Every unit is tested before it leaves this floor.

Size range: DN50 – DN1200

Pressure: PN10 · PN16

Body: Ductile iron GGG50

Seat: EPDM

Disc: SS304 / CF8

Sizes & prices

Eight sizes. Both pressure classes.

Prices are per piece, EXW Tianjin, in USD. Up to DN100 the two classes cost the same; above that PN16 carries a small surcharge, because the disc is thicker to hold the higher pressure.

On the order

What comes with every order.

One body

PN10 and PN16 are built on the same ductile iron casting. Going up a pressure class changes the disc, not the whole valve.

7–15 days

Packing and dispatch from Tianjin normally runs seven to fifteen working days. We confirm the exact date against current stock when we quote.

Per-batch testing

Every batch is pressure tested before it leaves. The test record travels with the shipment, not in a separate email.

Packing for sea

Individual bubble wrap, then carton or plywood case. Marks and labels to your instruction.
