Product Description

Metal hard-sealed high-temperature ball valve is a valve device that uses a ball as the valve core. Its working principle is based on the rotary motion of the sphere, and the fluid is cut off or circulated through the contact between the sphere and the sealing surface. This design makes the ball valve have the characteristics of rapid opening and closing, and can maintain good sealing performance under high temperature conditions.

First of all, the metal hard-sealed high-temperature ball valve has excellent high-temperature resistance. They use special alloy materials, such as Cr-Mo-Ti alloy, to ensure that they can withstand extreme working conditions in high temperature environment. This material selection enables the ball valve to maintain high strength and hardness in high temperature medium, thus providing reliable sealing and operating performance.

Secondly, the metal hard sealing high temperature ball valve has excellent sealing performance. Metal-to-metal contact is adopted between the ball and the sealing surface to form a rigid seal. This design makes the ball valve have good wear and corrosion resistance and can maintain a long service life in harsh working environment.

In addition, the metal hard seal high temperature ball valve has the characteristics of smooth fluid passage and small pressure loss. The rotary motion of the sphere can realize the state of full opening and full closing, which reduces the resistance and pressure loss of fluid passing through. This provides convenience for improving system efficiency and reducing energy consumption.

Metal hard-sealed high-temperature ball valves are widely used in the control fields of petrochemical industry, metallurgy, electric power, natural gas and other high-temperature media. For example, in an oil refinery, a metal hard-sealed high-temperature ball valve can be used for the import and export control of a fractionating tower and the shunt regulation of high-temperature gas and liquid. In the iron and steel smelting process, the ball valve can be used to control and adjust the flow of molten metal at high temperature. In power industry, ball valves can be used to control high-temperature water and steam piping systems in thermal power plants.

To sum up, the metal hard-sealed high-temperature ball valve plays an important role in the control field of high-temperature media with its high temperature resistance, good sealing performance and smooth fluid passage. With the continuous progress of industrial technology, the design and materials of metal hard-sealed high-temperature ball valves will continue to be optimized to meet more severe working conditions and provide more reliable solutions.

 

a) Unique, the metal seated ball valve with patented single-seat ball valve design. It has a flat spring set acting through a hard-faced bearing against the bottom ball shaft which provides sufficient initial ball-seat load for valve tightness, even at low delta P.

b) Metal seated ball valve proven in qualification tests and field operation to be solids-proof, even for the toughest applications on slurry service with solids particles.

c) Tightness rates: Allowable leakage rate at full Delta P: ASME/ FCI 70-2 Class VI/V. Tighter shutoff available upon request.
The leakage rate also can be customization from end-user request

d) The metal seated ball valve  with standard extension bonnet/stem, whose design base on the different temperature range.

e) Uni-directional or bi-directional sealing

The valve plate of the high-temperature sanitary ball valve and the sealing surface of the valve seat are oblique conical structures with temperature and corrosion-resistance alloy material welded on the inclined cone surface of the valve plate. These specialized alloys allow the valve plate and seat to withstand routine wear and tear caused by corrosive chemicals and abrasive mediums.

The spring fixed between regulating ring pressure plates is assembled together with the regulating bolt on the pressure plate. This structure effectively compensates for the tolerance zone between the sleeve and the valve body as well as the valve stem's elastic deformation from the system's high pressure. These components solve the valve's sealing problem in the process of two-way interchangeable medium transportation.
