L&T (Larsen & Toubro) manufactures a range of industrial valves, including cast steel gate valves, which are commonly used in various industries for regulating or isolating flow in pipelines. The specifications for L&T Cast Steel Gate Valves can vary depending on the specific model and application, but the general features and details are as follows:

1. Valve Type:

• Gate Valve: Used primarily for on/off flow control, where the gate (or wedge) fully opens or closes to stop or allow fluid flow.
• Cast Steel Construction: Provides high strength and durability under pressure, suitable for high-pressure applications.

2. Body Material:

• Cast Steel (WCB, WC6, WC9, etc.):
  • WCB: Standard carbon steel used for general service applications.
  • WC6 and WC9: Higher-temperature and pressure applications (alloy steels).
  • Other Alloys: In some models, special alloy steels or stainless steels (like 304, 316, or F22) may be used for more demanding conditions, such as high corrosion or elevated temperature environments.

3. Size Range:

• Common sizes for L&T cast steel gate valves typically range from DN 15 (1/2 inch) to DN 600 (24 inches), with larger sizes available upon request.
• Standard industrial sizes accommodate a wide range of pipeline applications.

4. Pressure Rating:

• PN 16, PN 25, PN 40 (European pressure ratings in bars)
• Class 150, Class 300, Class 600 (ANSI pressure ratings, typically in pounds per square inch)
• The pressure class indicates the maximum working pressure the valve can withstand at specific temperatures.

5. Temperature Range:

• Generally, L&T Cast Steel Gate Valves can operate within a temperature range of -20°C to 425°C for standard carbon steel valves (WCB).
• Higher temperature ratings are available for special alloys, such as WC6 or WC9.
• The temperature range is influenced by the body material and the specific trim materials used.

6. End Connections:

• Flanged Ends: The most common connection type, designed to conform to standards like ANSI B16.5 or ISO 7005.
• Butt Weld, Threaded, or Socket Weld: For smaller sizes or specific piping systems.

7. Seat and Trim Material:

• Stainless Steel (304/316) or Alloy Steel: Typically used for the gate, seat, and stem to ensure reliable performance and corrosion resistance.
• Bronze or Composite Materials: Sometimes used for softer sealing in lower pressure applications.
• Hardfaced Seats: In certain designs, materials like Stellite are used to enhance the durability and wear resistance of the valve.

8. Stem and Bonnet Material:

• Stem: Typically made from Stainless Steel (e.g., SS 410) or Alloy Steel to offer strength and resistance to corrosion.
• Bonnet: Usually made from Cast Steel or Stainless Steel to match the body material.
• Welded or Bolted Bonnet: For sealing the valve internals and ensuring pressure retention.

L&T's Class 150 gate valves are designed for reliable performance in various industrial applications. Below is an overview of their specifications:

Design and Construction:Standard: Manufactured in accordance with API 600 and ASME B16.34 standards.

• Body Material: Cast Steel (ASTM A216 Gr. WCB).
• Wedge Material: Cast Steel (ASTM A216 Gr. WCB) with 13% Chromium Steel for enhanced wear resistance.
• Stem Material: Alloy Steel (ASTM A182 Gr. F6a).
• Seat Ring: Hardened and Stellite-faced for improved sealing and durability.

Design Features:Bonnet: Bolted bonnet design for ease of maintenance.

• Stem: Rising stem with non-rising handwheel for clear indication of valve position.
• Wedge: Flexible wedge design to ensure tight seating over a wide range of differential pressures and temperatures.

Pressure-Temperature Rating:Class 150: Suitable for applications with pressure and temperature conditions as specified in ASME B16.34.

End Connections:Flanged Ends: Designed for bolted connections, typically conforming to ASME B16.5 standards.

Sizes Available:Commonly available in sizes ranging from 2 inches (50 mm) to 12 inches (300 mm).

Additional Features:Gasket: Flat-face joint with a graphite gasket having metallic inserts for Class 150 valves.

• Operation: Manual operation via handwheel; options for electric or pneumatic actuators are available upon request.
