Speciality Valve holds the top position as a premier Duplex steel valve manufacturer in India, serving regions such as Tamil Nadu, Uttar Pradesh, and Gujarat. A duplex steel valve, crafted from "duplex stainless steel," combines the corrosion resistance of austenitic stainless steel with the durability of ferritic stainless steel, achieving a unique balance of strength and corrosion resistance.

What is a Duplex Steel Valve?

A Duplex Steel Valve is a type of valve made from duplex stainless steel, which is a remarkable alloy with a unique metallurgical structure. Duplex stainless steel contains austenitic and ferritic phases in nearly equal proportions. This dual-phase structure provides a balance of strength, corrosion resistance, and durability. It is particularly well-suited for challenging environments.

Types:

  1. Duplex Steel Ball Valve: Ideal for high-performance applications, providing reliable shut-off and control with corrosion-resistant duplex steel construction.
  2. Duplex Steel Butterfly Valve: Ensures efficient flow control in large-diameter pipelines and corrosive fluid applications, offering low pressure drop and quick operation.
  3. Duplex Steel Check Valve: Prevents backflow in corrosive and high-pressure environments, safeguarding pumps and pipelines with reliable unidirectional flow control.
  4. Duplex Steel Gate Valve: Designed for high-pressure and corrosive environments, offering tight shut-off through a sliding gate mechanism for reliable isolation.
  5. Duplex Steel Globe Valve: Features a linear motion disk for precise throttling and control of fluid flow, suitable for accurate regulation in corrosive conditions.
