Product DescriptionOverviewThis ball valve features trunnion
mounted configuration, which has two-piece and three-piece valve
body structures. The body and bonnet are connected by bolts, and
the seal adopts reinforced PTFE embedded in the stainless steel
ring. It is suitable for long-distance pipelines and general
industrial pipelines. Due to its strength and safety, it
is suitable for various corrosive and non-corrosive media.Compared
with the floating ball valve, during working, the force generated
by the fluid pressure in front of the valve on the ball is all
transmitted to the bearing, and the ball will not move to the valve
seat, so the valve seat will not bear excessive pressure, so the
sealing performance is stable and the service life is
long.Features1. Labor-saving operation: The ball is supported by
the upper and lower bearings to reduce friction and eliminate the
excessive torque caused by the huge sealing load formed by the
imported pressure pushing the ball and the sealing seat. 2.
Reliable sealing performance: PTFE unisexual material sealing ring
is embedded in the stainless steel valve seat, and the end of the
metal valve seat is equipped with a spring to ensure sufficient
pre-tightening force of the sealing ring. When the sealing surface
of the valve is worn during use, it will be under the action of the
spring. The valve continues to ensure good sealing performance. 3.
Fire protection structure: In order to prevent the PTFE sealing
ring from burning due to sudden heat or fire, causing a large leak,
which will encourage the fire, a fireproof sealing ring is set
between the ball and the valve seat. When the sealing ring is
burned, Under the action of the spring force, the valve seat
sealing ring is quickly pushed to the ball to form a metal-to-metal
seal, which has a certain degree of sealing effect. The fire
resistance test meets the requirements of AP16FA and API607
standards. 4. Automatic pressure relief function: When the pressure
of the stagnant medium in the valve cavity rises abnormally and
exceeds the pre-load of the spring, the valve seat retreats away
from the sphere to achieve the effect of automatic pressure relief.
After the pressure is relieved, the valve seat automatically
recovers. 5. Self-Drainage: Drain holes are set up and down the
valve body to check whether the valve seat is leaking. During work,
when the valve is fully open or fully closed, the pressure in the
middle cavity can be removed, and the packing can be directly
replaced; the middle cavity can be discharged. Retentate, reduce
the pollution of the medium to the valve. Scope Nominal
