Innovation
This is our new design of Europe design for Europe market
Forgec Disc
Forged Duplex steel F53 disc for high pressure Class 600.
Integral Yoke
Yoke and body casting in whole,this new design is very beautiful and can avoid the leakage on yoke.
Flange face finish
The ASME B16.5 code requires that the flange
face(raised face and flat face)has a specific
roughness to ensure that this surface be compatible
with the gasket and provide a high quality seal.
Triple Eccentricity Design Features
The stem is offset on both the X (1)and Y (2) axis of the valve's
center line. This produces a cam一like motion. The third offset (3)
consists of an inclined conical profile machined into the valve
sealing surface. This allows rotary engagement and disengagement
of the seat and seal ring without interference. All rubbing
between seat and seal ring is thereby eliminated. Once the seat
and seal ring are fully engaged torque is applied in order to
create a bi一directional, zero leakage, metal-to一metal seal. For
this reason, triple offset valves are often defined as "torque" seated
rather than”position” seated as in the case of resilient or high performance products.
