DOUBLE BLOCK & BLEED (DBB)
When the ball is in the closed position, each seat seals off the process medium independently at the same time between the up/down stream and body cavity, it allows bleeding the trapped cavity pressure (DBB) through drain and vent valve. The double block and bleed function make it possible to flush the valve under pressure and verify that the seat are sealing properly.
DOUBLE ISOLATION & BLEED (DIB)
Double piston effect seat, medium pressure, both upstream and downstream as well as in the body cavity, creates a resultant thrust that pushes the seat ring against the ball, valve with double piston effect seat rings require a cavity pressure relief to reduce the build-up of over pressure in the body cavity.
Spring plus graphite type anti-static device are applied between the ball ,stem, gland Flange and body to keep the electrical Continuity between all the metallic components . And ensure the resistance lower than the most severe service requirement.
Blow-out proof stem:
The stem is made separately from the ball with integral T-type round shoulder, retained by bland .(other designs are Available on request)
Grease injection device
For DN150 (NPS 6) & larger the stem and the valve seat are provided with a sealing grease injection device, For DN125 & smaller, we can provide the sealing grease injection device according to customer requirements. When the O-ring is damaged by accident, by injected sealant sealed to prevent the media through the valve seat ring and stem leaks.
The ball is fixed by trunnion and stem for size 4” &smaller. Trunnion plate support for size 6” & larger
Soft seat: Metal to Metal O-Ring seal
Simple structure reliable sealing Applicable to particulate Reliable sealing low torque meet customers' high
wide application low cost. media conditions sealing reliability and low torque requirements
