Flanged high peformance Butterlfy valve
The disc motion of the double offset design provides many performance benefits:
DISC OPENING
Cam-action movement pulls disc away from seat.
Reduces seat wear.
OPEN POSITION
Disc does not contact seat.
Eliminates seat deformation.
Reduces operating torques.
Extends service life.
DISC CLOSING
Linear motion pushes disc onto seat.
Wiping action prevents undesirable material buildup.

Features
- The unique dynamic load seal PTFE seat design is adopted with good elasticity and high reliability
- Sealing can be maintained without the need of adding 0 ring or metal part
- The lip type sealing structure can compensate for the changes of temperature and pressure.
-Long service life and low maintenance.
-In seal test, there is no bubble and leakage at both directions.
Fire resistant structure
The fire-resistant type valve is subjected to fire test according to APl 607.
Seat type
EPDM, PTFE, R-PTFE, Fireproof seat, etc.
Reliable fixing of shaft
The anti-blow-out structure is provided at the top of the shaft to prevent the shaft from running out of the gland in case of accidental breaking of the shaft.
Convenient seat maintenance and servicing
The seat can be replaced just through removing the inserts without need of disassembling the butterfly valve and shaft.
Provided with shut-off and control functions
-Having excellent control characteristics-Proportional change of flow characteristic curve
- Wide adjusting range
- Tight sealing can be realized even when it is used for control.
