Size Range:
Flanged ends per ANSI B16.5 (and for 26″+ per ANSI B16.47 Series A/B). Socket weld & threaded ends as per ANSI B16.11 / ANSI B1.20.1. Butt weld ends per ANSI B16.25. Typical sizes from ½” up to 48″ or more (custom sizes on request).
Description
Fluent Valves’ gate valves are designed primarily for isolation (on/off) services and are not generally recommended for throttling. Built for durability and stability, our gate valves incorporate designs optimized for long service life even under extreme conditions.
We manufacture outside-screw & yoke (OS&Y), rising stem gate valves with backseat arrangements, ensuring safety, easy maintenance, and reliable sealing. Key working parts are renewable and made from SS 410 (13% Cr) by default, with alternate metallurgy options available.
Fluent’s gate valves support a broad array of actuation methods: handwheel, gear-operated, electric actuators, or pneumatic actuators. When torque exceeds 350 N·m, we offer gear operation. Optional features may include limit switches, position indicators, locking arrangements, and stelliting of seats for wear resistance.
We support advanced features such as pressure-seal bonnets, bolted bonnets, and compliance for sour service environments.
With a strong focus on matching global standards and client needs, Fluent Valves is among the leading gate valve manufacturers and suppliers in India, offering certified products for demanding applications such as hydrocarbons, cryogenics, hydrogen, oxygen, and fugitive-emissions control.
Features
- Efficient Shut-Off Performance - offers tight sealing when fully closed, minimal leakage.
- Unobstructed Flow - full bore (unrestricted flow) minimizes pressure drop.
- Modular Construction - parts can be replaced without full removal of the valve in many cases.
- Robust Design for High Pressure & Temperature - built for severe and critical services.
- Versatile Actuation - handwheel, gear, electric, or pneumatic options.
- Advanced Safety & Compliance - features like backseat, limit switches, stellited surfaces, IBR/NACE approvals.
- Wide Material Range - custom materials for corrosion resistance, high temperature, etc.
Applications
Gate valves from Fluent Valves are widely used in:
- Water & Wastewater Treatment (isolation in pipelines)
- Oil & Gas (petroleum transport, pipeline shut-off)
- Petrochemical & Chemical Processing
- Power Plants (steam, cooling, feed water)
- Marine & Offshore (ballast systems, isolating lines)
- Cryogenic & Gas Processing
- Severe & High Temperature Services
