PT FE、R-PT FE、 Fireproof valve seat, etc.
Reliable fixing of shaft
The top of the shaft has an anti blowing structure toprevent the upper end of the shaft from moving out ofthe cover in case of accidental breakage
Convenient seat maintainance and servicing
Simply remove the insert to replace the valve seat, withoutthe need to disassemble the butterfly valve and shaft.
Provited with shut alt and control tunctons
-Has excellent control characteristics;
-Proportional variation of flow characteristic curve;
-Wide adjustment range;
-Even when used for control, it can still be tightly sealed.
Using a unique dynamic load sealing PTFE valve seat design, it hasgood elasticity and high reliability:
No need to add O-rings or metal components to maintain sealing;
The lip type sealing structure can compensate for changes intemperature and pressure,
Long service life and low maintenance workload;
Sealing test, achieving no bubble leakage in both directions
