Alloy 20 Ball Valve
An Alloy 20 Ball Valve is a corrosion-resistant industrial valve designed for demanding chemical, acid, petrochemical, pharmaceutical, fertilizer, and process applications. Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium alloy developed for resistance to a range of aggressive chemical environments.
We supply Alloy 20 Ball Valves in different sizes, pressure classes, body configurations, seat materials, trims, and end connections according to customer requirements and project specifications.
These valves are particularly considered for applications where corrosion resistance and dependable isolation are important. The actual suitability of Alloy 20 must always be verified against the specific process medium, concentration, temperature, pressure, and operating conditions.

What Is an Alloy 20 Ball Valve?
An Alloy 20 Ball Valve uses a spherical ball with a precision-machined flow passage. The ball rotates approximately 90 degrees to open or close the valve.
When the ball bore is aligned with the pipeline, fluid can pass through the valve. When the ball is rotated perpendicular to the flow path, the valve isolates the pipeline.
Depending on the product design, Alloy 20 may be used for the valve body, ball, stem, or other wetted components.
Main Components
A typical Alloy 20 ball valve may consist of:
- Valve Body
- Ball
- Stem
- Seats
- Body Seals
- Stem Packing
- Gland
- End Connections
- Handle or Actuator
The exact materials and construction depend on the manufacturer’s design and project requirements.
Alloy 20 Material
Alloy 20, commonly known as Carpenter 20, is an austenitic nickel-iron-chromium alloy containing additions such as molybdenum and copper that contribute to corrosion resistance in selected environments.
It is widely associated with applications involving chemical processing and certain sulfuric-acid services.
Alloy 20 Corrosion Resistance
Alloy 20 can provide excellent corrosion resistance in many carefully selected applications, but its performance depends on the service environment.
Important considerations include:
- Chemical Composition
- Acid Concentration
- Temperature
- Pressure
- Chloride Concentration
- Oxidizing Conditions
- Reducing Conditions
- Fluid Velocity
- Contaminants
For critical services, material compatibility should be confirmed by a qualified materials or corrosion specialist.
Alloy 20 Ball Valve Types
Alloy 20 ball valves can be supplied in different configurations depending on the application.
1 Piece Alloy 20 Ball Valve
A compact one-piece construction suitable for selected industrial applications.
2 Piece Alloy 20 Ball Valve
A two-piece body design commonly used for industrial isolation applications.
3 Piece Alloy 20 Ball Valve
A three-piece construction that can provide convenient access to internal components for maintenance, depending on the manufacturer’s design.
Flanged Alloy 20 Ball Valve
Flanged connections are suitable for applications requiring bolted pipeline connections and convenient disassembly.
Threaded Alloy 20 Ball Valve
Threaded connections are generally used for selected smaller-size applications where threaded piping connections are appropriate.
Full Bore Alloy 20 Ball Valve
A Full Bore Alloy 20 Ball Valve provides a flow passage close to the nominal pipeline diameter.
This configuration can be selected where low pressure loss, pipeline cleaning, or flow-through characteristics are important.
Reduced Bore Alloy Ball Valve
A Reduced Bore Alloy 20 Ball Valve has a smaller internal flow passage than the nominal pipeline size.
Reduced-bore designs can be suitable where the application permits a smaller flow area.
