triple offset valves

Our special characteristics of the triple offset butterfly valves are:

1.       Replaceable seat:

The replaceable metal seat on body is connected by pins and bolts, which can be replaceable after the long time using and wearing of the sealing ring. Due to our precision processing machines, although the triple seat is in cone, DBV still makes out the seat perfectly contact with the sealing ring on disc.
