Alloy 20 Valves
Alloy 20 Valves are corrosion-resistant industrial valves designed for demanding chemical, acid, petrochemical, fertilizer, pharmaceutical, and process applications. Also known as Carpenter 20, Alloy 20 is a nickel-iron-chromium alloy used in selected environments where resistance to corrosion is an important material-selection consideration.
We supply Alloy 20 Valves in different designs, sizes, pressure classes, body materials, trim combinations, seat materials, and end connections for industrial projects in India, Saudi Arabia, the Middle East, and international markets.
Technical note: Alloy 20 is not suitable for every chemical service. Final material selection should be based on the actual fluid composition, concentration, temperature, pressure, contaminants, and other operating conditions.

Alloy 20 is particularly associated with chemical-processing applications and selected sulfuric-acid services.
Depending on the valve design, Alloy 20 can be used where improved resistance to specific corrosive environments is required.
Alloy 20 Valve Components
Depending on the design, components may include:
- Body
- Bonnet
- Ball
- Disc
- Plug
- Stem
- Seat
- Hinge
- Trunnion
- Springs
- Packing
- Gaskets
- Wetted Internal Components
Not every component necessarily needs to be Alloy 20. Material selection should follow the valve datasheet and process requirements.
Alloy 20 Material
Alloy 20, commonly called Carpenter 20, is an austenitic nickel-iron-chromium alloy with additions including molybdenum and copper.
Its composition provides corrosion resistance in a variety of selected chemical environments.
Alloy 20 is commonly considered for applications involving:
- Chemical Processing
- Sulfuric Acid
- Chemical Transfer
- Fertilizer Processing
- Pharmaceutical Processing
- Corrosive Industrial Fluids
Actual suitability must be verified for the specific service.
Alloy 20 Corrosion Resistance
The corrosion performance of Alloy 20 depends on the operating environment.
Important factors include:
- Chemical Type
- Chemical Concentration
- Operating Temperature
- Pressure
- Chloride Content
- Fluid Velocity
- Aeration
- Impurities
- Oxidizing Conditions
- Reducing Conditions
For critical applications, material compatibility should be confirmed by a qualified corrosion or materials engineer.
Types of Alloy 20 Valves
Alloy 20 Ball Valve
Alloy 20 Ball Valves use a rotating spherical ball to provide quarter-turn isolation.
Available configurations can include:
- Floating Ball Valve
- Trunnion Mounted Ball Valve
- 2 Piece Ball Valve
- 3 Piece Ball Valve
- Full Bore Ball Valve
- Reduced Bore Ball Valve
- Flanged Ball Valve
- Threaded Ball Valve
Alloy 20 Floating Ball Valve
A floating ball valve uses line pressure to assist seat loading when the valve is closed.
It can be considered for suitable chemical and process applications, particularly where a compact quarter-turn isolation valve is required.
Alloy 20 Trunnion Mounted Ball Valve
A trunnion-mounted ball valve mechanically supports the ball through upper and lower trunnions.
This configuration is commonly considered for larger sizes, higher pressure applications, and demanding industrial isolation services.
Alloy 20 Dual Plate Check Valve
An Alloy 20 dual plate check valve is designed to prevent reverse flow.
The spring-assisted dual plates open with forward flow and move toward the closed position when flow decreases or reverses.
Alloy 20 Swing Check Valve
An Alloy 20 Swing Check Valve uses a hinged disc that opens with forward flow and closes when reverse flow occurs.
It can be used for suitable chemical and process applications requiring non-return functionality.
Alloy 20 Gate Valve
An Alloy 20 gate valve can be considered for isolation applications where the valve is normally operated fully open or fully closed.
Possible configurations include:
- Bolted Bonnet
- Pressure Seal
- Rising Stem
- Non-Rising Stem
- Flanged
- Weld-End
Alloy 20 Globe Valve
Globe valves can be used for isolation and selected throttling applications.
Alloy 20 globe valves can be considered for compatible chemical and process services where the material provides the required corrosion resistance.
Alloy 20 Plug Valve
Plug valves use a rotating plug to control flow.
Possible designs include:
- Lubricated Plug Valve
- Non-Lubricated Plug Valve
- Sleeved Plug Valve
- 3 Way Plug Valve
The correct plug and sealing material should be selected based on process conditions.
