API602 Forged Steel Gate Valve
The API 602 Forged Steel Gate Valve is designed for small-diameter high-pressure pipelines used in critical industrial applications.
- Product Introduction
Product Overview
The API 602 Forged Steel Gate Valve is designed for small-diameter high-pressure pipelines used in critical industrial applications.
Forged steel construction ensures uniform material density and higher mechanical strength compared with cast valves, making it suitable for continuous operation under pressure fluctuation, thermal stress, and demanding process conditions.
It is widely applied in oil & gas, petrochemical, power generation, and other industrial systems where safe isolation and long-term reliability are required.
Key Features
Forged steel body construction provides high mechanical strength and excellent resistance to internal pressure, making it suitable for continuous service in high-pressure pipeline systems.
Compact API 602 design reduces face-to-face dimensions and overall weight, allowing easy installation in space-limited skid systems and compact valve stations.
Bidirectional sealing structure ensures reliable shut-off performance even under pressure fluctuation or reverse flow conditions in critical isolation service.
Low operating torque stem and wedge design reduces manual effort and improves compatibility with gear operators and actuators in industrial applications.
Material options such as ASTM A105, F11, and F22 allow stable performance in high-temperature and high-pressure environments such as steam, refinery, and chemical systems.
Applications
Oil and gas production and transmission systems
Refinery and petrochemical processing units
Steam and boiler systems in power plants
Chemical and industrial processing pipelines
High-pressure gas and fluid isolation lines
Skid-mounted and modular piping systems
