TOP ENTRY BALL VALVE from our company 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,sealing face are  stand wear and tear eliable saaling,convenience for operation and maintenance,open and close quickly,as well as start and close flexibly.


  1. One piece body design for the top entry ball valve.

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.Advantage top entry ball valve .

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.The top entry ball valve  usually use on petroleum ,natural gas and impotant piping line,this valve can use pressure up to 2500LB, so the price of this valves is higher than other type ball valve.


4.All of our ball valve are antistatic design. between the ball and seat triboelectrification when we open or closed the ball valve.on account of the seat and packing usually use the PTFE material,the static electricity can not through the stem to the body, so we we need install a metal hoodle, the static electricity just past the stem and  metal hoodle to the body.thus Eliminate the static electricity.


5.Only the soft seal top entry ball valve need fire safety design.for the soft sealing,we usually use the PTFE as a seat, the PTFE seat will melt and the medium will through the valve leakage out  when the fire happened,so we need make a meatal seat installed in the back of the PTFE seat, the metal seat can continue to seal when the PTFE seat melting,the valve no need fire safety design when the sealing are metal to metal.


6.All of our ball valve can installation of electric actuators and pneumatic actuators

The top flange of the ball valve designed to ISO5211,which is convenient for connection and exchange of various drivers,the common driving types are manual, electrical, pneumatic and pneumatic/ hydraulic.

1、Fire Safe
Orbit ball valve
When the trunnion ball valve be used normally, it sealed by seat and ball surface, seat retainer sealed by O-ring and body, these are soft sealed, reliable sealing. When the seat and O-ring are burnt, the seat retainer and ball will be metal to metal sealed directly, Also the seat retainer and body will be sealed by expanded graphite, thus act the anti-fire purpose.

When the floating ball valve be used normally, it sealed by seat and ball reliably. When the seat is burnt, the body moved and metal to metal sealed with ball directly, thus act the antifire purpose.
In order to act anti-fire safe, the valve other connective position all have the anti-fire sealing ring.
2、Anti-static device

In order to prevent friction between ball and stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident, in this ball valve, static-conduction spring is set between the stem and the ball, the stem and the body. Thus static electricity is conducted to ground and system safety is secured.
3、Sealed construction of vavle body free of body leakage

The connective position of valve body and bonnet is double sealed by gasket and O-ring, on this base, such factors as fire, high temperature, shock and uneven opening or closing of the torque all can't induce external leakage.
4、Special seat structure

With years of manufacturing experience, double sealed structure of elastic seat was designed. When the pressure going up, the T value will be increased continuous, it will act good sealing performance under the codition of low pressure, high pressure and vacuum.
5、Emergency sealing (For trunnion ball valve only)
OBRIT BALL VALVE
When the sealing of stem or seat is damaged to induce leakage, the compound can be used to do the secondary sealing.
6、Seat spring protective structure (For trunnion ball valve only)

With the spring protection, the impurity can't enter into spring hole, thus protect the spring from impurity.
7、Double block (For trunnion ball valve only)

The single valve is installed in front of sealant fitting, double sealing, reliable sealant, the body safety is secured.
8、Double bleed (For trunnion ball valve only)

The valve is installed NPT drain valve and release valve, it can be released pressure and cleaned during the operation of valve.
9、Various  end connections

Can offer various connection: RF, RTJ, BW, NPT, Wafer, etc.
10、Low torque in operation
The self-lubricated bearings are installed ot the friction of stem, resulting in wear resistance, flexiblility of operation and low torque.
11、Various driving methods
The valve top work dimension is designed according to ISO 5211, which is convenient for connection and exchange of various drivers. The common driving types are manual, worm gear, pneumatic, electrical, hydraulic.
12、Extension stem
For the underground installed valve, the stem can be lengthened and for the convenience of operation, the corresponding compound injection nozzle, drainage valve and release valve can be extended to the top of the valve.
13、Automatic cavity relief
OBRIT BALL VALVE
When the body pressure going up un-normally as the unstable factor, the trunnion ball valve downstream seat will be pushed by un-normally pressure, and release the unnormally pressure automatically, it doesn't damage to the sealing of upstream seat. The un-normally pressure which in the floating ball valve body will release the pressure into the upstream pipe directly, it doesn't damage to the sealing of the downstream seat.
