Stainless steel ball valves have a hollow, perforated, or pivoting ball to control the flow of water, oil, gas, or other compatible fluids. We carry a variety of quarter turn ball valves. You'll find the stainless ball valves you need in our large inventory, in sizes ranging from 1/4" to 4".
As steel ball valve suppliers to agricultural, petrochemical, beverage and brewery, and water utility and plumbing industries, we know our customers' various needs and strive to have the stainless steel ball valves they need in stock and ready to ship. These valves are durable and versatile. They're capable of controlling the flow of watery or viscous fluids or gases used in chemical processes for manufacturing or energy. Stainless ball valves are resistant to corrosion and can endure high temperatures and pressure.
Quarter-turn ball valves help prevent leaks. When a pipe leaks liquid or gas, it's not only dangerous, but it's also expensive and wasteful. Find the stainless ball valves you need here at Direct Material today.
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.
