Specification of this Handle Operated Rubber Lined Wafer Butterfly Valve

The Lined Butterfly Valve is a reliable, leak-free service valve designed for a wide range of demanding requirements in corrosive chemical applications and process industries. Lined wafer butterfly valve is split body designed for a wide variety of liners such as PTFE, EPDM, NBR, FPM, PU to fit a wide range of applications.

PTFE is the preferred material for corrosive applications in chemical industry.
PU is the preferred material for abrasive applications.
EPDM is the preferred rubber for water industries.
NBR is the preferred rubber for oil transportation.
FPM is the preferred rubber for wide range of medium composition and temperature.
Wafer design makes the valve convenient for connection between flanges and save length in pipe line.

Product advantage of this Handle Operated Rubber Lined Wafer Butterfly Valve
1. ISO5211 direct mounting pad for easy automation
2. Isolation height according to plant prescription
3. Dirtscraper prevents moisture penetrating into the shaft area
4. Three PTFE impregnated SS316L bearings are provided for precision alignment of the disc-shaft
5. 3 layers sealing system ensures environment protection
6.PTFE seat and rubber seat version interchangeable each other• PTFE-liner for chemically toxic and highly corrosive media, rubber liner for various of industry applications
7. Silicon rubber energized back behind PTFE seat makes the sealing between liner and disc stable and offer a wide range of temperature
8. One-piece disc-shaft design reduces the valve torque and increases Kv
9. PTFE or rubber lined disc design option avoids high cost by expensive metal in corrosive applications
10. Bubble-tight shut of at full pressure rating
11.Can be disassembled, material-specific recycling possible
12. Wave shape flange face design ensures the flange sealing of seat face not damaged by flange pressing, also avoids shrink of seat inside diameter because of flange pressing
