Flanged Resilient Seated Butterfly Valves
- Features
- Technical Data
▪ Rounded polished disk guarantees the concentricity of disk and seat. This results in low torque, good sealing and long service life.
▪ Replaceable seat design reduces maintenance cost |
|
▪ Top built-in bearing provides the best support, reduces friction and lengthens the service life ▪ Self-adjustable dual-V gland packing, with the automatic compensation and the two-way sealing characteristics, ensures that objects cannot pass through the stem into the body ▪ Molded-in O-ring provides positive flange sealing and eliminates the need for gaskets. With positioning hole, for convenient installation and centering between the flanges ▪ ISO 5211 top mounting plate available, for easy actuation ▪ Optional: actuator |
