About:

The side-mounted eccentric half ball valve structure design is similar to the three-eccentric hard seal butterfly valve, which has the advantages of light operation, no friction, zero leakage and long service life.

Product features:

First, sealing pair (spool, seat) - bimetal, to achieve metal spherical belt hard seal, fire and explosion proof;
Second, the seal is tight, the seal of the spool and the seat is spherical line contact, and zero leakage is achieved by three-dimensional eccentricity;
Third, the valve core of the sealing pair has a compensation amount, and when the valve is used for a long time and the sealing pair is worn, it only needs to loosen the limiting bolt on the hand wheel side, and then turn a little when it is closed, it can still achieve reliable sealing and extend the service life.
Fourth, the pressure sleeve can be screwed off, adjust or replace the seat, the valve can still continue to use, to avoid the current many valve seal failure after the whole set scrapped drawbacks.
Side-mounted eccentric half ball valve products are divided into: general valve, pipeline valve, slurry special valve, gas special valve, petrochemical special valve, coal injection special valve six series. Transmission methods are manual, pneumatic, electric three, eight pressure levels (PN0.25 ~ 10.0Mpa) hundreds of specifications (40 ~ 1000) half ball valve products. In petroleum, chemical industry, metallurgy, electric power, gas and other industries is the gate valve, globe valve, Y valve, ball valve replacement products. At present, it has been sold in the steel industry of pulverized coal injection, alumina industry of pulp, mother liquor and aluminum oxide powder transportation, hydraulic (or dry) ash removal in the power industry, petrochemical industry, gas industry and other occasions.

Scope of application:

General valve: reasonable design, compact structure, with small flow resistance, good sealing, light and flexible operation, especially suitable for water, sewage, steam, pulp and other media of low-pressure pipe network, can be prepared electric and pneumatic devices, can achieve remote automatic operation. (Water, steam, sewage, pulp, mud and other non-corrosive media)
Pulverized coal injection special: used to control the dust containing gas, particle fluid pulverized coal injection and other solid transport ideal equipment, widely used in metallurgy, mineral processing, electric power and other production processes in the blast furnace pulverized coal injection, powder system and dust removal system in various pipeline control. It adopts straight-through structure, the flow channel is smooth, there will be no ash blockage phenomenon, the sealing pair is made of Co-Cr-W alloy material, after special heat treatment, the valve is resistant to erosion and wear, and the valve eccentric spherical surface has automatic compensation performance, through the worm gear adjustment bolts, so that the sealing pair in a certain degree of wear, can still achieve the effect of re-sealing. (Dusty gas, particulate fluid)
Special for petrochemical industry: For the petrochemical industry to use high pressure, high temperature, full of flammable, explosive, general weak acid and weak alkali easy to corrode the medium, with good sealing, corrosion resistance, light opening and closing, can automatically cut the valve surface scale and other characteristics, suitable for crude oil, heavy oil and other media transportation and oil cracking, food production and other processes. (Oil, natural gas, gas, water, etc.)
Blast furnace gas, gas special: the sealing pair is made of CR-MN-Si cemented carbide, fire-proof, explosion-proof and anti-static, the sealing pair is resistant to high temperature 560℃, its corrosion resistance and anti-bite ability are more than 6 times that of stainless steel sealing pair, especially suitable for gas, coke oven gas, water gas, liquefied gas, natural gas pipeline transmission and pressurized door station. (blast furnace gas, natural gas, dusty gas, etc.)
Slurry mixed fluid special: conveying easy to precipitate scale, crystallization of solution pulp, slurry ash slag and other process processes in the two phase mixed fluid medium ideal process valve, can break the scale barrier when closed to achieve smooth closure. It has the advantages of novel structure, unique design, high efficiency and energy saving, good wear resistance, reliable sealing, light operation, quick opening and closing, long life, etc. (Transportation of granular materials such as process slurry and slurry ash)
Pipeline special: belongs to the straight-through half ball valve, no diameter reduction, the valve body channel and the pipeline connected into a straight pipe, the cross-sectional area is equal, the resistance is less than the diameter reduction, fully open, fully closed as long as the rotation of 90 degrees can be achieved, convenient long-distance pipeline transmission control. (Pulverized coal injection and gas transmission).
