Design Description Of High Quality Forged Steel Full Bore High Pressure Ball Valve：
Double block and bleed design(DBB)
Double stem sealing. The ball can maintain pressure sealing of pipeline when it is closed or fully opened.
Shorter upper sleeve reduces bearing load and operation torue
Limit device ensures the accurate opening and closing position of the valve
The vall and stem are separated so as to reduce stem load. The stem adopts anti-blow-out design.
The sealing surface is inserted into te metal seat by polymer or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Reduce the opening torque and prolong the service life of the valve. Stem leakage can be prevented through the emergency grease fitting.
Nickel and phosphor treatment to the parts can enhance the anticorrosive performance.
The fireproof design of metal wound gasket compassed of stainless steel and graphite can prevent external leakage.
Usage/Applications Of High Quality Forged Steel Full Bore High Pressure Ball Valve:
It can be widely used in Metallurgy, Mine, Petrochemical, Chemical, Oil & Gas transmission pipeline, Power plant, Heating power and Pharmacy, etc.
Main Test Of High Quality Forged Steel Full Bore High Pressure Ball Valve:
Packaging & Delivery Of High Quality Forged Steel Full Bore High Pressure Ball Valve:

- Q: 1 and 1/2 ball valve is how much?
- 1 and 1/2 ball valves, DN40mm.The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
- Q: Ball valve specifications are represented by 2 FF,
- FF refers to the form of connection between the valve and the pipe lineFF, or Flat Face, is a common form of flat flange connection
- 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: Hard sealing ball valve, what method can calculate the leakage? How much is grade 4? How much is grade 5? How much is level 6? For example: how many DN150 seals are 5 ml?
- Valve leakage level is used as an important reference standard in valve leakage test.Usually in accordance with the requirements of the process. In the process of lifting the conditions and processes, there will be valve leakage level requirements.
- Q: What does "F" and "C" mean in the Q11F-16C of the ball valve?
- This model is not international standard number, but still can see, of which, F refers to the sealing material: fluorine plastic, C refers to the body material: carbon steel.
- Q: One stainless steel ball, two pieces, three pieces of difference, use
- Three piece ball valve has the following advantages:1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
- Q: Is the water inlet valve good or the ball valve well?
- Good with the gate valve, the ball valve requires more space than the gate valve.
- Q: Is the ball valve switch in front of the water meter or after the water meter?
- the owners of their own decoration or repair, in front of the water meter is generally C type locking valve or valve, if less water, property control, no special key you open
- Q: Calculation formula of ball valve flow
- The sectional area of diameter of DN15, DN25 and DN50 is respectively:DN15:15*3.14/4=176.625 mm, 0.0177 square decimeter.DN25:25*3.14/4=490.625 mm, 0.0491 square decimeter.DN50:50*3.14/4=1962.5 mm, 0.1963 square decimeter.A pipe flow rate of V=4 M / s V=40 decimeter / s, and the 1 liter =1 cubic meter, the pipe flow respectively (cross-sectional area multiplied by the velocity):DN15 pipe: flow Q=0.0177*40=0.708 L / sec,It's 2.55 cubic meters per hour.DN25 pipe: flow Q=0.0491*40=1.964 L / sec,It's 7.07 cubic meters per hour.DN50 pipe: flow Q=0.1963*40=7.852 L / sec,It's 28.27 cubic meters per hour.Note: a flow rate must be given to calculate the flow rate, which is calculated in accordance with 4 meters per second. Reference: http://zhidao.baidu /question/77687541.html answer: good night dream | six | 2010-5-24 22:46It's 600 cubic meters / hour!Flow Q=600 m3 / h = 0.167m^3/sThe flow rate is V=4Q/ (3.1416D^2) = 4*0.167/ (3.1416*0.090^2) = 26.25 m/s, and the flow velocity is very large!It could be 600 cubic meters per day:Flow rate Q=600 m3 / day = 0.00694 m^3/sFlow rate V=4Q/ (3.1416D^2) = 4*0.00694/ (3.1416*0.090^2) = 1.09 m/s flow rate is normal.
- Q: Home tap water valve (ball valve) half open or well open, open half is not love rust live?
- The valve should be fully open the valve open the key is not half open it love rusted because the material inside is processed in general but you will not rust after scouring the semi open water surface changes so that it may be rusty (see you what material is the core surface treatment not original) and this makes serious at bad seat valve sealing effect was lostIn fact, it is necessary to use special control valve to control flow size ~!
