Design Features
Application

Small fluid resistance.
Only a small force is required for opening/closing.
No limitation on the flowing direction of the medium .
During opening and closing process, the friction between the disc wedge and the seat is small, so the sealing is reliableensuring reliable tightness and long service life.
The valve is designed in a backward sealing structure, ensuring no medium leakage in the stuffing box, reliable tightness and online filling replacement.
The valve stem sealing is realized by the collaboration of flexible and woven graphite, ensuring a more reliable tightness.
BB-BG-OS&Y, two structures of rising (OS&Y) and non-rising stem gate valves structures
