Grease Injection Design on stem
For trunnion mounted ball valve 6 inch and larger will be installed with a sealant injection fittings on the both stem and seats. When the sealing material (seat sealing or stem “O”-ring) are damaged. Leakage from the seat and stem can be prevented by injection of sealant into these fittings.
Grease Injection Design on seat
The injection systems in ball valves are emergency injection. If the valve have any leakage.
Full port/full bore
Full bore 100% open according to API 6D standard.
Raised face joint (RTJ)
RTJ surface is very clear and smooth.protected them very carefully without any surface scratch during processing the valve
Hook Design
It is more easier
to handle or carry
Standard Bolts & Nuts
DBV ball valve adopts the standard bolts and nuts. It could
extend the valve longer service life.
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 ball.
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.
