Grease Injection Design On Stem
DBV trunnion ball valve （DN≥150，NPS6）adopts the design of grease
injection. It is effectively avoiding the leakage caused by the stem "O"rings are unexpectedly damaged.
Grease Injection Design On Seat
injection. It is effectively avoiding the leakage caused by the seat rings
are unexpectedly damaged.
When the valve is closed, the pressure in the body cavity will be
accumulated , and the pressure is removed by opening the blow-off
Drain Valve Design
The seal of the trunnion ball valve is achieved by the floating seat.When
the waste of the inner cavity is removed through drain valve, the
pressure will exist between the inlet and outlet end of the compression
seat, and it is easier to achieve the sealing performance.
Standard Bolts & Nuts
DBV ball valve adopts the standard bolts and nuts. It could
extend the valve longer service life.
DBV trunnion ball valve design forms a electrostatic channel through ball, stem and body.
This structure leads the electrostatic spark to the earth caused by the friction between the
ball and the seat. This structure could avoid the fire disaster and explosive accident.
The platform design is convenient for assembling worm gear, pneumatic, electric, hydraulic and
pneumatic & hydraulic actuators.
