Up Blow-out Proof Design
Disc fixed on the stem with two pins without Chink to prevent the disc
shaken. DBV butterfly valve adopts such design of stepped shaft with
the gland. It is effectively that prevent the stem blows out from the top.
Internal Snap Ring and Bottom Cover Design
DBV butterfly valve adopts the unique stem design. The bottom of
the stem is slotted. The ring is embedded to prevent the stem blow
out. Then, the snap bottom cover plays a same role. This design
suits for the valve which is larger than four inches.
Standard Bolts & Nuts
DBV ball valve adopts the standard bolts and nuts. It could extend the
valve longer service life.
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.
Multi-layer disc sealing ring
Multi-layer disc sealing ring adopts ss304 and graphite laminated, sealing by
the inside graphite, applied for low and middle pressure, as recycle water, swage
treatment, city building, etc.
