Description

Forged Steel IBR Gate Valve Manufacturer in India

Forged steel IBR gate valves provide reliable positive shut-off for high-pressure steam lines, power plants, boiler feed piping, and critical process systems. Unitek Valves manufactures, supplies, and exports high-performance forged steel gate valves engineered for extreme thermal cycling and high-pressure service. Certified under Indian Boiler Regulations (IBR Form III-C), our compact valves ensure zero-leakage isolation and operational safety across India and international markets.

What is a Forged Steel IBR Gate Valve?

A forged steel IBR gate valve is a heavy-duty, linear-motion isolation valve machined from solid forged steel blocks to start or stop fluid flow.

• High Mechanical Strength: The forged grain structure eliminates internal porosity, offering superior resistance to pressure surges, mechanical fatigue, and thermal shock compared to cast valves.

• Full-Bore Positive Shut-Off: Raising the solid wedge completely out of the flow path ensures straight-through flow with minimal pressure drop.

• Compact Pressure Containment: Ideal for small-bore, high-pressure piping where space is limited and absolute tight shut-off is mandatory.

Key Features & Construction

• OS&Y Design (Outside Screw & Yoke): External stem threads remain isolated from line media, protecting against high-temperature wear and corrosion while offering a clear visual position indication.

• Solid Wedge & Stellite Trim: Precision-machined wedge with hardfaced seating options (Stellite / 13% Cr) to resist high-velocity steam erosion, wire-drawing, and galling.

• Forged Bolted Bonnet: High-tensile alloy studs compress a stainless steel spiral-wound gasket for a leak-tight body-bonnet joint with easy inline maintainability.

• Versatile End Connections: Available in Socket Weld (SW), Threaded (NPT/BSPT), and Butt Weld (BW) end connections to suit specific piping requirements.

Materials & Pressure Ratings

• Common Materials: Forged Carbon Steel (ASTM A105) for standard steam and boiler feed lines; Alloy Steels (F11, F22) and Stainless Steels (F304, F316) for superheated steam or corrosive media.

• Pressure Rating: Class 800 is the standard compact high-pressure rating (governed by API 602 / ASME B16.34) for high-pressure steam distribution headers, blowdown lines, and drain systems.

Applications

• Boiler House & Steam Piping: Main steam lines, boiler drum drains, soot blower manifolds, gauge glass isolation, and continuous blowdown systems.

• Power Generation: Thermal power plants, co-generation units, turbine drains, and high-pressure feedwater loops.

• Process Utilities: High-pressure utility steam networks across chemical, textile, paper, and refining plants.
