Description:
OUYI ORBIT BALL VALVE is mainly used in pipeline and industry system and it has a top entry and
on line maintenance function.It has a lot of advantages,such as small fluid resistance,simple
structure,small volume,light weight,reliable sealing,convenience for operation and maintenance,open
and close quickly,as well as start and close flexibly.
1.One piece body
One piece body is used for the body to guarantee sufficient strength and rigidity under maximum
rated operating pressure.The internal parts of valve are carefully designed and selected to ensure
reliability under all kinds of operating condition.Enough margin wall thckness and adaptation of high
strength connective bolts are convenient for valve maintenance and sufficiency to support the stress
from piping.
2.Maintenance on line
Its most difference from common ball valve is that its maintenance can be made on pipe line and
without dismounting from the pipe line.The back space seat structure is adopted for the seat and
the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting
back space of seat.
3.Low operation torque
OVIKO ORBIT BALL VALVE has a trunnion mounted ball,whose surface is ground,polished and hard
face treated.The ball and stem is integrated,sliding bearing is installed on the external bore so that
the friction radius is small and operation torque is very low.
4.Emergency sealing
Compound injection holes are designed and compound injection valves are installed at locations of
stem/cap and body support of side valve.When sealing of stem or seat is damaged to induce leakage,
the compound can be used to do the second time sealing.A concealed check valve is installed in side
of each compound injection valve to prevent compound from out flowing due to the action of
transmitter substance.The top of the compound injection valve is the connector for fast connection
with compound injection gun.
5.Reliable sealing
The seat sealing is formed by seat sealing and metal retainer component.The seat retainer floats
axially and low pressure sealing of valve seat is reached by pre-pressure of spring.In addition,the
piston effect of valve seat is designed reasonably,which realized high pressure .by the pressure of
operating medium and realize the interception of retainer to form the sealing of the body.The
expansion graphite ring is designed to realize sealing under fire condition.

6.Double block&bleed(DBB)
When ball is full open or close position,the transmitter substance in center cavity of body can be
released by drainage and emptying devices.In addition,the&
