Alloy 20 Gate Valve

Middleeast Valve is leading manufacturer and exporter of high performance Alloy 20 Gate Valve, providing dependable solution designed for extreme service condition. Among our specialty product, the Alloy 20 Gate Valve is remarkable for the outstanding corrosion resistance particularly in chemical and petrochemical application.

 An Alloy 20 Gate Valve is line motion valve constructed with Alloy 20, a corrosion resistant alloy primarily made of nickel, chromium, iron and molybdenum. The gate valve is intended for on and off flow regulation and perform particularly well in the presence of sulfuric acid, chloride and other aggressive chemical.

 Major Components

  1. Valve Body: Made of Alloy 20 for high corrosion protection.
  2. Gate (Wedge): The adjustable component that opens or closes to regulate flow.
  3. Stem: Links the handwheel or actuator to the gate.
  4. Bonnet: Encloses the valve internals and preserves pressure integrity.
  5. Seat Rings: Offers sealing surfaces for leak-tight shut-off.

 Working Mechanism

The valve works by raising the gate out of the fluid’s path to open, and returning it to its place to close. This is normally achieved by a handwheel or actuator, depending on the application.

 Advantages

  • Better resistance to sulfuric acid and chloride stress corrosion
  • High temperature and pressure resistant
  • Tight closure with low pressure drop
  • High service life with low maintenance
  • Both liquid and gaseous medium compatible

 Industries Most often applied in:

  1. Chemical processing
  2. Petrochemical refineries
  3. Power plants

 Why is it Needed?

In corrosive conditions, regular materials break down rapidly. The Alloy 20 Gate Valve ensures long term stability, safety, and operation where other materials do not.
