Specialityvalve is best Duplex Steel Valve Manufacturer in India. Duplex Steel Valves are constructed from duplex grade steels. The microstructure of the duplex grade contains austenitic and ferritic phases, giving it high strength and corrosion resistance. Because of their metallurgy, these steels can be used in a variety of applications. This material is used to make valves that are dependable, strong, and corrosion resistant. Duplex stainless-steel valves are classified into three types: standard duplex, super duplex, and lean duplex. Each of them outperforms the former in terms of corrosion and strength. Valves of various types, such as ball valves and gate valves, are used for specific purposes in an application.
Specialityvalve is the best Super Duplex Gate Valve Manufacturer in India. These products are used in a variety of industries including chemical, petrochemical, energy, pulp, paper, and oil and gas processing. Various valves are available. Gate valves are usually manufactured in India.

Applications of Gate Valve:
• Chemical Industry
• Oil & Gas
• Water & Waste Water treatment plants industry
• Petrochemicals Industry

How does a Gate Valve work?
It is basically operated by a hand wheel, a valve T-Key, or an actuator. The wheel attached transfers rotational energy to it. The rotational of the hand wheel turns the threads of the gate stem into the gate and vice versa for closing. An extension spindle is installed for underground gate valves to conduct operations without direct access to the valve.

Advantages of Super Duplex Gate Valve:
• Provides excellent pressure drop with fewer operations
• Can be used in both directions
• Suitable for high pressure and high temperature
• Low maintenance
