Stainless steel ball valve can be divided into straight-through type, three-way type and right-angle type according to its channel position.
Stainless steel three-way ball valves are T-shaped and L-shaped.
The T-type can make the three orthogonal pipes connect with each other and cut off the third channel to play the role of diversion and confluence.
L-type can only connect two pipes that are orthogonal to each other, and can not keep the third pipeline connected to each other at the same time, but only play a role of distribution.
The stainless steel ball valve itself is compact and easy to operate and maintain. The ball valve body can be integral or combined.
Generally perpendicular to the pipe installation.
QA41W stainless steel ball valve is compact and easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas, as well as for media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
The ball valve body can be integral or combined.
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.
