Renewable seat metal to metal seat triple eccentric butterfly valve

 PS: We also can do according to customer's requirements.

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.
