Product overview
    PBQ340 side-mounted eccentric hemispherical valve is successfully developed on the basis of digestion and absorption of the clip-on large-flow straight-through valve produced by a German company. Its structure adopts the principle of eccentricity and tightness to achieve the purpose of tightening, adjusting, and closing through the transmission mechanism. The sealing pair is a seal with a hard surface in contact with the metal surface ring. When the double eccentric structure is opened, the valve core is located in the ball chamber, the flow cross-section is large, and the valve is not washed away. When it is closed, the valve core is not washed away. When the valve seat is opened, the spherical surface of the valve core is asymptotically close to the valve seat, effectively removing fouling obstacles and achieving reliable sealing.It is particularly effective for the transportation of mixed streams where two-phase mixed streams are prone to fouling and solid precipitation.
        The second feature is that the hemispheres of the valve are bimetal. Different alloys are surfaced on the base material, and the valve seat is also surfaced accordingly. After special treatment, the sealing surface is combined into various types such as anti-corrosion, wear-resistant, and high strength to meet the needs of different occasions. The third feature is tightly sealed, and the delivery of harmful gases can reach zero leakage. The fourth feature is that the valve core of the sealing pair has a compensation amount. When the valve seat is worn out (the hardness of the valve seat is lower than that of the valve core), turn it a little when it is closed, it can still be reliably sealed and extend the service life. In addition, the user unscrews the compression nut and the valve seat can still be used after adjustment or replacement, avoiding the disadvantages of many current valve seals that fail and the whole unit is scrapped.Therefore, the selection of bimetal sealing pairs for surfacing different alloys (or combination balls) can be used in different industrial sectors that require strict sealing such as wear resistance, corrosion resistance, and high temperature resistance.

 

The main uses and characteristics of the product:
1. The universal valve is suitable for occasions with strict requirements such as sewage treatment, pulp, urban heating, etc.
2. Special valves for oil-chemical industry are suitable for crude oil, heavy oil and other types of oil products, weak corrosion in the chemical industry, and two-phase mixed flow media.The temperature resistance can be 425C.
3. The special valve for gas is suitable for the delivery control of gas, natural gas and liquefied petroleum gas.The product structure is characterized by different chromium-containing stainless steel surfacing with sealing pairs, which are tightly sealed and corrosion-resistant.
4. The slurry is specially suitable for industrial pipeline transportation where there is crystallization, precipitation or fouling of chemical reactions in liquid and solid two-phase mixed flow or liquid transportation.The product structure characteristics are based on different media and temperature requirements according to customer needs. The sealing sub-surfacing valve core is surfaced with chromium-molybdenum-vanadium alloy, and the valve seat is surfaced with chromium-molybdenum alloy, chromium alloy, and stainless steel alloy electrode to meet the needs of different slurry delivery.
5. The special valve for pulverized coal ash is suitable for the control of power plants, hydraulic slag removal or gaseous pipelines.The product requires wear resistance. The valve core adopts combined ball bimetal, which has quite high stiffness and is very wear-resistant. The valve seat adopts integral wear-resistant No. 1 or full surfacing, and it has the advantage of hard-sealed ball valve.
