1.Anti-fire safe design.Anti-static device 
2.Free leakage of body Sealed construction 
3.Double block&bleed. 
4.Extension stem.

1.Bow-out proof stem

 

For the purpose of preventing the stem from flying off  resulting in abnormal rising of the inner pressure of valve,shoulder is fixed at the lower part of the stem.In addition,in order to prevent leakage resulting from burnout of packing set of the stem in a fire,thrust bearing is set at the contact position of the shoulder at lower part of the stem and valve body.Thus an inverse seal seat is formed which will prevent leakage and avoid accident.

 

2.Anti-fire safe design

 

When the trunnion ball valve be used normally,its sealed by seat and ball surface,seat retainer sealed by O-ring and body,this is soft sealed and reliable sealing.When the seat and O-ring are burnt,the seat retainer and body will be sealed by expanded graphite.Thus act anti-fire safe purpose.

 

3.Anti-static device

 

In order to prevent friction among ball,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.

 

4.Free leakage of body Sealed construction

 

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.

 

5.Low torque in operation

 

The self-lubricated bearings are installed at the friction of stem,resulting in wear resistance,fiexibility of operation and low torque.

 

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.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.

 

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.Automatic body cavity relief

 

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 the release the unnormal pressure automatically,it doesn't damage to the sealing of upstream seat.

 

10.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.

Q:Buy Ball Valves
Not let you buy the entire valve, you take this valve to the building materials market, see the valve handle can be sheathed in your valve stem, the valve handle is arranged to buy, your valve
Q:Is the ball valve the same as the float valve?
Ball valve and float valve is a kind of valve, the ball valve is a valve inside the ball, it is called the ball valve
Q:Butterfly valve and ball how to distinguish from the appearance
To say the difference, the biggest difference is that the butterfly valve is a piece of open and close, and the ball is a ball. They work by spinning their own axes!(1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;(2) butterfly valve structure is relatively simple, low pressure general use butterfly valve, butterfly valve the maximum pressure can only reach 64 kilograms. Ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.(3) butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric three, the eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg;(4) the valve can also be divided into soft seal and seal, soft seal valve can reach the highest temperature below 280 degrees, the pressure is below 64 kilograms, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms.
Q:What does copper ball valve type Q11F-16T mean?
Q11F-16T, Q refers to the ball valve, 1 refers to the connection mode, the latter 1 refers to the straight through type, F refers to the sealing material, 16 refers to nominal pressure, T refers to the main material for copper material
Q:Is the ball valve switch in front of the water meter or after the water meter?
It's in front of the water meter. What's the problem?.
Q:Is a plastic ball valve, connecting France is hot melt.
Visible, electric ball valve in daily life, industrial manufacturing and other fields have great application and market space. With the development of the times, the electric valve also put forward higher requirements, such as digital remote control, so the development of this industry, cannot do without the progress of technology, from the past to the ordinary valve electric valve electric valve to now, by the digital intelligent valve, look first to the application of new technology on the product rapidly the transformation and development of new products to meet market demand.
Q:What's the diameter of the 4 point ball valve?
4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.
Q:How can a steel ball in a steel ball valve be put in?
This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.
Q:What is the difference between PPR ball valve and PPR live ball valve?
PPR and PPR union ball valve is different: PPR union ball valves and pipes on both sides (hot melt) connected between, a movable joint (hot melt) and (link with) nut, maintenance, convenient disassembly and replacement of the valve, the union not only cut off the PPR ball, maintenance.
Q:Must I use the ball valve for the heater?
Valve main points and angle valve, ball valve in the water pressure is large enough to use, angle valve can increase the pressure of a little water.
