Typecasting
Every valve in DBV with clear typecasting.Our big size butterfly
valves also can comply with the leakage class A.(Zero Leakage).
Seat ring
seat ring Stainless steel ASTM A351 CF8,We processing
them with CNC lathe processing center.
Sealing
Precise processing on the disc sealing to ensure
Zero leakage.
Metal to metal seats
Metal to metal seats can endure severe flashing, hydraulic
shock, abrasive process fluid, and high temperatures up
to and exceeding 1,000° F. They are also ideal for high
erosion or corrosion applications.
Top flange
The top flange design comply with ISO 5211,The yoke
is convenient for assembling worm gear, pneumatic, electric,
hydraulic and pneumatic & hydraulic actuators.
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.
