# 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**: These valves are made from high-quality forged steel, ensuring durability and resistance to corrosion and high temperatures.
– **Design**: The valves feature a compact design, making them ideal for installations where space is limited.
– **Pressure Ratings**: They are available in pressure ratings from Class 150 to Class 1500, catering to a wide range of industrial applications.
– **End Connections**: The valves can have threaded, socket weld, or butt weld end connections, providing flexibility in installation.
– **Seat and Disc**: The seat and disc are typically made from materials that offer excellent sealing properties, such as stainless steel or stellite.

## Applications of API 602 Forged Gate Valves

API 602 forged gate valves are used in a variety of industries due to their reliability and performance. Some of the key applications include:
