Inspection and Testing: API 598, GB/T 13927

Product Specification
Body Material:
WCB, ASTM A395 , CF8 ,CF8M

Lining Material: PTFE , PFA , PO ,FEP, EPDM

Nominal Diameter: 2"-80"(DN50~DN2000)

Pressure Range: Class150 , PN6 , PN10 , PN16

Connection Type: Flange ,Wafer , Lug Connection

Operation Method: Manual ,Worn gear ,Electric ,Pneumatic actuator

Products Decription:

1. The lined butterfly valves bi-directional flow is possible at maxmium operating pressure. Since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.

2. It features ease of maintenance, repeatable on-off, long life durability.

3. The concentric design is commonly used in the power generation, brewing, water and food industries and suitable for both gaseous and liquid service. Typically applied in chemical/petrochemical process, food and beverage, and pulp and paper etc.

4. Lining material: PTFE, PFA, FEP, GXPO etc.

5. Connection type: wafer, flange, lug etc.

6. Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.

7. Youfumi lined three-way ball valves are available as per the needs of applications in additional sizes and other than standard materials.

Primary and Secondary Shaft Sealing
 
The primary seal is formed by the flexible, spherically molded liner, sealing against the matching spherically machined disc hub when compressed by the resilient elastomer backup liner. The PFA liner as well as the PFA shaft over-molding extends into the valve body itself. Tight compression is maintained at the hub area and around the shaft by the resilient back-up liner combined with the flexible PFA liner, forming an independent secondary seal.
 
Upstream/Downstream Sealing
 
The dense PFA body liner is flexible, and allows the resilient elastomer back-up liner to compress the spherically molded PFA liner into the spherically machined shaft-disc with enough force to create a tight seal. This is in contrast to PTFE liners which are usually thick sinterings resulting in a stiff liner unable to give tight shut-off over a long period of time. The wide elastomer backup liner in the rests in a machined body
groove which is essential in providing tight shutoff for end of line service at full pressure. This has enabled the valve to be used for pump and
vessel isolation as well as other difficult services.
 
Safety Sealing
 
A third seal is provided by a graphite filled PTFE safety seal, which provides force against the junction of the PFA liner and PFA over-molded shaft. This seal is constantly energized by a coil spring, and self compensates for temperature changes and wear.
 
Flange Sealing
 
Provided by compression of the liner between the valve body and the flanges. An elastomer o-ring, fitted underneath the PFA liner, allows
proper flange sealing with warped flange faces or in vacuum applications.
