DIN Standard PN40 Ceramic Ball Valve




The all parts of Full-lining Hard-Sealing Ceramic Ball Valve in contacting other medium are made of structure ceramic. This structure ceramic has a super performance in wear resistance, corrosion resistance, and well in heat insulation.
Our Ceramic Ball Valve is processed by the precision grinding technology with the advanced equipment and product lines. The structure of ball valve body is so fine and concise. The flow channel of the ball valve is so smooth that the flowing medium has least resistance.
Full-lining Hard-sealing Ceramic Ball Valve is made up of six components by the scientific and rational design way. The valve ball and the valve seat ring are processed by the face- contact tooling. With this processed way, the ball can inosculate fully with intrados and out-radian of the valve seating ring. With the advantages of high precision roundness , good surface, light- torsion and least resistance of the valve ball, the ball valve can be meet the require of zero-leaking seal.

Due to its good antifriction property, our valve has an absolutely advantage when fit in transport high hardness granule medium, and soft with erosive medium.
Applicable medium: water supply, petrochemical disposal, boiler heat, limewater and grain-seawater transport and flue gases desulfurize and ash discharge. The ball valve can be made of different material for different use. The ball valve is suit for different temperature and different use-circumstance.

Ceramic ball valves applied to Pulverized coal injection system

Currently, in high furnace of metallurgy technique, techniques of high wind, high temperature, refined steel, injection oxygen enrichment have been widely used to save cost and increase production. Furnace injection techniques have been widely used for some places where lack of coke and small high furnace. Actually, for places where does not lack of coke, high furnace injection has not been adopted. Along with lacking of coke, cost increasing of coke meanwhile ceramic lined pipe, elbow and valves are growing maturely, more and more steel factories adopt high furnace injection techniques.

1. Meaning of pulverized coal injection
Pulverized coal injection is an important revolution for high furnace metallurgy. Pulverized coal injection refers that injecting refined coal from high furnace to replace coke and offer heat and reducer. The significance of pulverized coal injection list as below:
1) Using cheap coal to replace expensive furnace coke, which can reduce coke ratio and cost of metallurgy significantly.
2) Pulverized coal injection could be a way of adjusting furnace conditions.
3) Pulverized coal injection could adjust furnace working conditions and make furnace work smoothly.
4) It can increase wind temperature and create oxygen-enriched blast. Coal injection could reduce theoretical burring temperature before wind.
After High furnace injects coal fines, coal gas increases meanwhile it will consume heat to warm coal fines.
The amount heat that injecting coal fines brings is a few. When coke enters tuyere, coke will be well heated up to 1450~1500℃.The temperature of coal fines will be less than 100℃.

The hydrocarbon in the coal fines needs heat to decompose.
The coal fines have more hydrogen than coke brings. Hydrogen increases reducing power and penetration diffusion capacity, which will be helpful for ore reduction and improve high furnace operation.

Coal injection replace partial coke, which will relieve lack of coke and reduce investments of building coking plant
Currently ceramic is applied for pipe and valves, which have solved abrasive problem of coal injection, reduce cost and increase working performance.
2. Introduction of pulverized coal injection process
It mainly includes two procedures: coal fines making and injection:
1) Coal fines producing system adopt vertical middle-speed fast grinding. Electric motor actuated reducer makes millstone rotated. Raw material will be sent to millstone from feed port of feeder. Under pressure of centrifugal force, raw material will enter roller way from all around and become powder with power of roller way.
2) Under weight of roller way and pressure device, raw material will become powder. Because there is not only rolling between roller way and millstone, raw material will get several stresses, which will increase grinding capacity and efficiency. Hot air enters tuyere and millstone from bottom body.
Because there is air distributing ring in the gap of rotated millstone and bottom body, it can be evenly distributed in the millstone along with air of air distributing ring.
3) Grinded material will be blew up. Qualified powder will go out along with air and these collected by dust collector are finished products. Bigger powder will be redistributed in the millstone under effect of air distributing ring and get reground. This procedure will cycle and recycle all the time. These small steel pieces mixed with material in the millstone will be blew out from rotated millstone and fall down on the bleeding hole. Foreign material will be cleaned as long as bleeding hole is open periodically.

Injection system make us of high pressure air to inject coal fines from injection tank to high furnace directly.
During this procedure, high-speed col fines will abrade elbow, pipe and valves seriously, so all pipe, elbow and vales of injection system should be lined with ceramic. Usually fully lined ceramic ball valve are applied. Structure ceramic has performance of high hardness, high strength, anti-corrosive and anti-abrasive. After grinding seat and ball precisely, ceramic ball valves could reach zero leakage, which can make sure of excellent sealing performance and have a very long service life under seriously erosion of high-speed coal fines.

Typical Applications:
For some very hard particles or serious erosive mediums, general metal seated wedge gate valves will be washed out and damaged easily due to the abrasion and or corrosion. As a professional and experienced ceramic valve manufacturer, FUVALVE developes ceramic wedge gate valves to solve the corrosion and abrasion problems for wedge gate valves.
FUVALVE’s ceramic wedge gate valves are very suitable for those mediums contain fibers and hard solid particles, such as  below listed typical applications:
Mining slag
Coal washing 
Ash Slurry
Suspension
Oil with particles
Catalyst


Design Features:

Product type

1. Ceramic wedge gate valves have two main structures: bolted (BB) bonnet type for low pressure ratings and pressure seal bonnet (PSB) for higher pressure.

2. Inlet seat and outlet seat are ceramics materials. By using the high hardness and high strength of high pure 99% Al2O3 ceramics, FUVALVE ceramic wedge gate valves have much longer service life than general metal seated wedge gate valves in similar conditions.

3. Two ceramic sealing rings are inserted to both sides of wedge gate. Besides the inlet and outlet seats are also ceramics, this ceramics-to-ceramics design can avoid abrasion and corrosion, which makes ceramic wedge gate valves have much longer service life than general metal seated wedge gate valves.

4. The actuation of FUVALVE ceramic wedge gate valves can be hand wheel, electric motor and hydraulic actuator, special requirements are available on customer’s require.
