Grease Injection Design On Packing Gland
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
DBV trunnion ball valve （DN≥150，NPS6）adopts the design of grease injection. It is effectively avoiding the leakage caused by the seat rings are unexpectedly damaged.
Blow-off Design
When the valve is closed, the pressure in the body cavity will beaccumulated and the pressure is removed by opening the blow-off valve.
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.
Outer Trunnion Ball
The trunnion ball is the standard deisign for ball valves, which
guarantees an easy assembling into valve, a wide surface for
washers (reducing friction and torque).The ball can only turn
around its own axe (trunnion axe) and sealing is guaranteed by
the axial movement of the seats for springs or inline pressure.The
trunnion design is suggested for medium and big dimensions and
enables to avoid high torque during opening or closing phase with
inline pressure. The critical issue for these products consists in the
poor material between the bore and the washer area it occurs an
easier deformation of the ball for high pressure and consequently leakage between seats and bal.
Inner Trunnion Ball
This structure is suitable for small size valve or higher pressure
environment. With simple design and convenient maching, this
ball guarantees a stronger resistance of the ball than the outer,
and so less deformation in high pressure condition reducing the
risk of leakage between ball and seats. However, it's critical for
the valve assembling especially for big dimensions; limited space
for washers.
