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.
Corrosion Resistant
The first reason that makes stainless steel valves extra special is that they are resistant to corrosion. In an industrial domain, this feature is extremely important. Stainless steel ball valves quickly passivate, forming a corrosion-resistant layer at its surface. Thus, these valves thrive in a moisture-laden environment.
Durable
A stainless steel valve is incredibly durable. It provides super abrasion resistance and also rejects erosion in dangerous settings, such as sand particles in high-speed gas streams. Likewise, a steel valve also effectively dodges shock damage from impacts caused by a water hammer. Thus, owing to its durability, steel valves are ideal for heavy-duty applications like mining.
Versatile
The third benefit of a stainless steel valve is versatility. Steel is an alloy, and is usually composed of chromium, molybdenum, and nickel. These three elements can be adjusted to cater to specific project and industrial needs, such as an increase in strength, being corrosion resistant, and more.
Tolerance to High Pressure and Temperature
Last but not least, a major benefit of stainless steel ball valves is that they work incredibly well in high-temperature and very high-pressure applications. For instance, ferritic grades are appropriate for operating between 1022 degrees Fahrenheit and 1562 degrees Fahrenheit.
They Utilize a hollow ball that rotates allowing a flow through it when aligned and stops the flow when it is in a closed position. A quick 90 Degree turn of the handle is all that is needed to fully open or close the valve flow.
When the handle is parallel and in-line with the pipe, then the valve is open. When the handle is perpendicular and at right angles to the pipe, then the valve is closed. It is this 90° turn either clock wise or anti-clockwise to open or shut the flow of the valve ,that led them to also be known as quarter-turn valves.
The valve has an internal rotary ball with a hollow bore running through the center. This Inner ball is connected to the handle via a stem. So by turning the handle the ball rotates and when the hollow bore is aligned with the pipe and the in same direction as the flow, then the flow is open, and when the bore is perpendicular to the flow, then flow is shut off.
| Stainless Steel Ball Valves | Brass Ball Valves | |
| Material Composition | Iron alloy made from nickel and chromium (and sometimes molybdenum) | Copper alloy that includes zinc and occasionally additional metals |
| Cost | More costly than leaded and lead-free brass ball valves | Less costly than stainless steel ball valves, more costly than plastic ball valves |
| FDA Approval | Approved by the FDA for use in the food and beverage industry | Not approved by the FDA unless certified lead-free |
| Softness | Harder than brass, making it more challenging to seal (for example, by welding) | Softer than stainless steel, making it more easy to seal (for example, via welding) and more efficient to machine |
| Corrosion Resistance | Highly corrosion resistant; the preferred material for use in corrosive environments, including marine applications | Can withstand corrosive environments better than plastic but not as well as stainless steel; however, can be compatible with some materials not compatible with stainless steel |
| Pressure Ratings | Higher pressure ratings than brass; more resistant to high pressure | Lower pressure ratings than stainless steel; less resistant to high pressure |
| Temperature Resistance | Can handle and last longer at higher temperatures than brass ball valves | Not as suitable for high temperature situations as stainless steel ball valves |
