Gate Valve Manufacturer

At Steel Icon Stainless Pvt. Ltd., we are a leading manufacturer of industrial Gate Valves, offering high-strength isolation solutions for large-diameter and high-pressure pipeline systems. Gate valves are designed to allow unrestricted, full-bore fluid flow when fully open and tight shut-off when closed. Their design eliminates flow resistance and is ideal for systems that require minimal pressure drop and infrequent operation.

We manufacture rising stem and non-rising stem gate valves in solid wedge, flexible wedge, and parallel slide designs, available in flanged, socket weld, butt weld, and threaded ends. Complying with API 600, ASME B16.34, BS 1414, and DIN standards, our gate valves are trusted across refineries, power plants, water systems, and marine engineering.

Applications

Gate valves are ideal for systems that require complete fluid isolation with minimal flow resistance, including:

Oil & Gas Pipelines – Block valve for long-distance transport and distribution
Water Treatment & Distribution – Isolation valve for potable, industrial, and irrigation lines
Power Plants – Steam, feedwater, and cooling systems
Petrochemical Plants – Process fluid cut-off valves
Marine & Offshore – For seawater intake and ballast systems
Industrial Infrastructure – Plant shutdown valves and main line isolators

Key Benefits

Full Bore Flow Path – Supports cleaning pigs and reduces pressure drop
Bidirectional Sealing – Ensures tight closure in either flow direction
Low Maintenance Design – Fewer parts reduce downtime and wear
Customizable with Fire-Safe & Cryogenic Features
Wide Material Availability – Suitable for corrosive, abrasive, and clean media

Frequently Asked Questions

Explore our FAQs for insights on materials, customization, and delivery.

Can gate valves be used for throttling?

No. Gate valves are best used in fully open or closed positions. Throttling causes wear and flow instability.

What stem type should I choose?

Rising Stem: Visual position indication
Non-Rising Stem: Best for underground or confined spaces

Are your gate valves API 600 certified?

Yes, we manufacture gate valves compliant with API 600 and API 6D with full inspection and documentation.

Do you provide actuated gate valves?

Yes. Options include electric, pneumatic, and hydraulic actuators with ISO or customized interfaces.

What is the lead time for bulk valve orders?

Standard orders ship within 3-7 days, while custom orders take 7-14 days, depending on requirements.
