# API 602 Forged Gate Valve Specifications and Applications

Forged gate valves are essential components in various industrial applications, particularly in high-pressure and high-temperature environments. Among the most widely recognized standards for these valves is the API 602 specification. This article delves into the specifications and applications of API 602 forged gate valves, providing a comprehensive overview for engineers, procurement specialists, and industry professionals.

## Understanding API 602 Forged Gate Valves

API 602 is a standard developed by the American Petroleum Institute (API) that specifies the requirements for compact steel gate valves. These valves are typically forged, making them robust and suitable for demanding applications. The standard covers valves with sizes ranging from NPS 1/2 to NPS 2, and they are designed to handle pressures up to Class 1500.

### Key Specifications

API 602 forged gate valves are characterized by several key specifications:

– **Material**: The valves are made from high-quality forged steel, ensuring durability and resistance to corrosion and high temperatures.
– **Design**: They feature a compact design, making them ideal for installations where space is limited.
– **Pressure Rating**: These valves are available in various pressure classes, including Class 150, 300, 600, 900, and 1500.
– **End Connections**: They come with different end connections such as threaded, socket weld, and butt weld, providing flexibility in installation.
– **Seat and Disc**: The valves are equipped with hard-faced seats and discs, enhancing their sealing capabilities and longevity.
