Key Features

Application Scope: The Alloy 20 Valves are popular in sulfuric acid, chemical plants, pharmaceutical manufacturing, sea water systems, pulp and paper mills, food processing lines and other corrosive industrial environments that need the service of durable valves.

Material & Corrosion Performance:

The excellent level of nickel, chromium, copper and molybdenum gives better resistance to:

Mixed acid streams & sulfuric acid.
Stress corrosion cracking caused by chloride.
Crevice and pitting corrosion in seawater exposure.
Handling of nitric and phosphoric acid.
Oxidizing & reducing media

Valve Design & Standards

Depending on the service conditions in the engine, valves are designed and produced according to international standards in the industry including API, ASME, ANSI and DIN. They are applicable in isolation, back flow prevention, throttling and continuous flow regulation.

Technical Attributes

Good acid and chloride corrosion resistance in acidic and chloride conditions.
Good high temperature mechanical stability.
Sealing with minimum operation torque Leak-tight.
Manual, electric, and pneumatic actuated.
Adherent to significant standards of ANSI / ASME / API.
Capable of working under cyclic pressure and thermal variations.

Available End Configurations

Flanged (RF / RTJ)
Butt Weld (BW)
Socket Weld (SW)
Threaded (NPT)

Alloy 20 Valves – Clients & Project Supply

Alloy 20 Valve is used in industrial chemical and refining plants since they have been tested to perform well under corrosive and high-temperature service conditions. Engineers consider compatibility with process media, corrosion type, temperature, pressure group, and final connection type so that there is a maximum system dependability.
