Description:
OUYI TOP ENTRY 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 saaling,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 maitenance and sufficiency to support the
stress from piping.
2.Top entry
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 top entry series 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 sealing 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 over loaded pressure in the center cavity
of valve can be released to low pressure end by self relief seat.
7.Anti-static and fire safe design
The fire prevention design of valve meets the requirement in API6FA/API607 standard and the design
of the anti-static conforms to regulations in API6D and BS5351.
8.Extension stem
For the underground installed valve,the stem can be lengthened and for the convenience of
operation the corresponding compound injection nozzle and drainage valve can be extended
to the top of valve.
9.Various driving types
The top pad of valve designed according to ISO 5211,which is convenient for connection and
exchange of various drivers.The common driving types are manual,electrical,pneumatic and
pneumatic/hydraulic.
Applications:
large and medium oil, gas, water conservancy, pharmaceuticals,Chemical, heating equipment industry
