Forged Steel Gate Valve

Forged Steel Gate Valve is a robust and high-performance type of Gate Valve primarily used for reliable on/off isolation in demanding service lines. The key distinction lies in its construction method: critical components like the body and bonnet are made from forged steel, a process that enhances the material's grain structure, resulting in superior mechanical strength, impact resistance, and integrity compared to cast equivalents. This makes it the preferred choice for high-pressure, high-temperature, or critical applications involving volatile fluids.

As a certified manufacturer with integrated production and stringent quality control, Wenzhou Chenyu Valve Co., Ltd. (Chenyu Valves) supplies high-quality Forged Steel Gate Valves across these three bonnet designs, manufactured to international standards (such as ASME) for reliable performance in petroleum, chemical, power, and other critical industries.

Main Features of Forged Steel Gate Valve

Advantages of an 800LB Forged Steel Gate Valve

1. High Pressure Handling: Rated for 800 PSI, it can withstand high-pressure environments without failure.

2. Durability: The forged steel construction provides excellent strength and resistance to wear, making it ideal for critical applications.

3. Minimal Flow Resistance: The gate design offers minimal flow resistance when the valve is fully open, making it suitable for applications that require a full, unobstructed flow.

4. Long Service Life: Due to the forged steel material, these valves have a longer operational life, especially in harsh environments.

5. Leak-Free Operation: When closed, the valve offers a tight seal to prevent leakage under high pressure.

End Connection Types

1. Socket Weld End: The pipe is inserted into a socket in the valve body and welded around the periphery. Provides strong, leak-proof joints, superior to threaded connections for high-vibration services.

2. Threaded (NPT) End: A tapered pipe thread connection. Ideal for smaller lines (within the specified size range) where welding is not preferred or for easier installation and maintenance.

3. Butt Weld End: The valve end is beveled to match the pipe end, and a full-penetration weld is performed. This is the strongest connection, preferred for highest-pressure systems, high-temperature applications (like steam), and services where fugitive emissions must be minimized.

Forged Steel Gate Valve Conforming Standards

This valve is engineered to meet specific and rigorous international standards that define its design, testing, and interchangeability:

• Design & Manufacture: API 602 - This is the core standard for Compact Steel Gate Valves. It specifically governs the design, material, and manufacturing requirements for small-bore, forged steel gate valves, ensuring robustness for severe service.

• Inspection & Testing: API 598 - Mandates the testing procedures for valve inspection (shell test, seat test), guaranteeing leak-tight integrity and performance reliability.

• End Connections: Complies with relevant standards for each type:

  • Threaded (NPT): ANSI B1.20.1

  • Socket Weld: ANSI B16.11

  • Butt Weld: ANSI B16.25
