Description

Forged Steel Gate Valve Manufacturer in India

Unitek Valves is a leading Forged Steel Gate Valve Manufacturer in India, offering compact and robust industrial isolation valves for high-pressure and demanding process applications. Based in Mumbai, India, we manufacture, supply and export forged valves for steam, oil & gas, refineries, petrochemical plants, power plants, chemical industries and industrial piping systems.

A Forged Steel Gate Valve is manufactured from forged material, providing a dense and uniform structure suitable for demanding pressure and temperature conditions. Its compact construction makes it particularly suitable for small-bore piping systems where reliable isolation, strength and long service life are required.

Our product range is available with bolted bonnet or welded bonnet construction, rising stem (OS&Y) design and various end connections including Socket Weld (SW), Threaded/NPT, Butt Weld and Flanged Ends, depending on size, pressure class and project specifications.

API 602 Forged Steel Gate Valves

Unitek manufactures API 602 Forged Steel Gate Valves in accordance with applicable international standards and customer specifications. Design and testing requirements can include API 602, ASME B16.34 and API 598, depending on the applicable valve configuration and project requirements.

API 602 valves are commonly selected for compact, small-bore piping applications requiring robust construction and dependable shut-off performance.

Our manufacturing and inspection process focuses on:

• Pressure integrity
• Reliable seating performance
• Dimensional accuracy
• Material compliance
• Smooth stem operation
• Proper gland and bonnet sealing
• Applicable pressure and leakage testing

Different trim and seating combinations can be provided according to the operating medium, pressure and temperature.

ASTM A105 Forged Gate Valves

A105 Forged Steel Gate Valves are widely used for carbon steel piping applications requiring good mechanical strength and pressure containment. ASTM A105 forged carbon steel can be offered for suitable temperature and service conditions.

Depending on the process requirement, other forged material grades can include:

• ASTM A105 / A105N Carbon Steel
• ASTM A182 Gr. F304
• ASTM A182 Gr. F316
• ASTM A182 Gr. F11
• ASTM A182 Gr. F22
• ASTM A182 Gr. F51 Duplex
• Other forged alloy and stainless steel grades on request

Material selection should be based on the process medium, design pressure, design temperature, corrosion requirements and applicable piping specification.

Class 800 & Class 1500 Forged Steel Valves

Our forged gate valves are available in pressure ratings suitable for demanding industrial piping systems, including ASME Class 800 and Class 1500, subject to size, end connection, material and design requirements.

Class 800 Forged Steel Gate Valves are commonly supplied with socket weld or threaded connections for small-bore high-pressure piping applications.

For more demanding operating conditions, Class 1500 Forged Gate Valves can be supplied according to applicable design requirements and project specifications.

Higher pressure configurations can also be evaluated depending on valve size, material, end connection and required standard.

Socket Weld & Threaded Gate Valves

Unitek supplies Socket Weld Gate Valves for applications where a welded piping connection and compact valve construction are required. Socket weld ends are commonly used in small-bore industrial piping systems operating at elevated pressures.

Threaded and NPT Gate Valves can also be supplied for suitable applications where screwed connections are specified.

Available end connections include:

• Socket Weld (SW)
• Threaded / Screwed
• NPT
• Butt Weld (BW)
• Flanged Ends

The appropriate connection is selected according to piping class, pressure rating, installation requirements and customer specifications.

Bolted Bonnet & Welded Bonnet Design

Depending on the application, forged valves can be supplied with bolted bonnet or welded bonnet construction.

A Bolted Bonnet Forged Steel Gate Valve provides a conventional bonnet-to-body connection suitable for various industrial services.

A Welded Bonnet Forged Steel Gate Valve provides a compact body-to-bonnet arrangement and can be selected for applications where the specified piping or project design requires welded bonnet construction.

Both configurations can be offered with a rising stem and OS&Y arrangement according to the applicable design standard.

IBR Approved Forged Steel Gate Valves

Unitek Valves also supplies IBR Approved Forged Steel Gate Valves for applicable boiler and steam service requirements. Inspection, testing, certification and documentation can be provided according to applicable IBR requirements and agreed project specifications.

IBR-approved forged valves can be considered for applications such as:

• Boiler Systems
• Steam Lines
• High-Pressure Steam Piping
• Power Plants
• Process Steam Systems
• Thermal Power Applications

Material, pressure class and trim are selected according to the specified steam conditions and applicable project requirements.

Testing & Quality Control

Valves are inspected and tested according to applicable standards and approved project requirements. Depending on the specified inspection plan, testing may include hydrostatic shell testing, seat leakage testing and functional inspection.

Material Test Certificates and other quality documentation can be supplied according to the purchase order and project requirements.

Additional inspection or testing requirements can also be accommodated when agreed during order finalization.

Industrial Applications

The compact design and forged construction make these valves suitable for a wide range of demanding industrial services, including:

• Oil & Gas
• Refineries
• Petrochemical Plants
• Power Plants
• Boiler & Steam Systems
• Chemical Industries
• Process Plants
• High-Pressure Piping
• Utility Lines
• Industrial Process Systems

Different materials, trims and pressure classes allow the valve configuration to be selected according to specific operating conditions.
