Scope of application

General valve: reasonable design, compact structure, with small flow resistance, good sealing, portable and flexible operation, especially suitable for water, sewage, steam, pulp and other media of the low-pressure pipe network, can prepare 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 of pulverized coal injection and other solid transportation of the 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 of various pipeline control. The sealing pair is made of Co-Cr-W alloy material. After special heat treatment, the valve is resistant to erosion and wear. At the same time, the valve eccentric spherical surface has the performance of automatic compensation. (Dusty gas, particulate fluid)

Special for petrochemical industry: For the petrochemical industry to use high pressure, high temperature, full of inflammable, explosive, general weak acid and weak alkali corrosion easy medium, with good sealing, corrosion resistance, light opening and closing, can automatically remove the valve surface scaling 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 hard alloy, fire-proof, explosion-proof, anti-static, sealing pair 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 the solution slurry, slurry ash slag and other processes easy to precipitate scale, crystallization precipitation of the optimal two-phase mixed fluid medium process valve, can be closed when the scale barrier can be broken 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, and long service life. (Transportation of granular materials such as process grout, slurry and ash)

Pipeline special: belongs to the straight 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 90 degrees can be achieved, convenient for long-distance pipeline transmission control. (Pulverized coal injection and gas transmission).

Main shape and connection dimensions unit:mm

Product Features:

1. Sealing pair (spool, seat) -- bimetal, metal spherical ring hard seal, fire and explosion proof;

2. Tight seal, the sealing of spool and seat is spherical line contact, and zero leakage is realized by three-dimensional eccentricity;

3. The valve core of the sealing pair has a compensation amount. When the valve is used for a long time and the sealing pair is worn out, it only needs to loosen the limiting bolt on the hand wheel side and turn a little when it is closed, it can still achieve reliable sealing and extend the service life.

Four, the pressing 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 disadvantages.

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 modes 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 slurry, mother liquor and aluminum oxide powder transportation, power industry of hydraulic (or dry) ash removal, petrochemical industry, gas industry and other occasions.
