Power Station Gate Valve, 20CrMoV, API 600, DN250, PN100, BW

The Power Station Gate Valve adheres to API 600 and ASME B16.34 standards, constructed from 20CrMoV alloy steel. It features a pressure seal bonnet, DN250 (10-inch) diameter, and a Class 600 LB (PN100) pressure rating. The valve has BW ends for secure connections, making it suitable for high-pressure applications in power stations.

Product Name: Power Station Gate Valve, Pressure Seal Bonnet
Design Standard: API 600, ASME B16.34
Body Material: 20CrMoV Alloy Steel
Size: DN250, 10 Inch
Pressure: PN100, Class 600 LB
End Connection: BW
Operation: Bare Stem

Our pressure seal gate valves are engineered in compliance with API 600 and ASME B16.34 standards, making them ideal for high-temperature and high-pressure applications. These valves are commonly used in fossil fuel power plants. Unlike bolted bonnet joint valves, pressure seal gate valves provide a more reliable and secure sealing of the bonnet joint. This design makes the valve more compact, rigid, and cost-effective for maintenance in demanding service conditions, ensuring long-term performance in high-temperature and high-pressure environments.

Product Features

Pressure seal gate valves are designed to deliver outstanding performance in steam-generation stations, industrial chemical plants, and thermal power plants. Available in both cast steel and forged steel body designs, these valves offer versatility for various applications. The simple structure ensures reliability, while the design allows slight flexible deformation to compensate for deviations in the sealing face angle during processing, improving performance. Additionally, the seat and gate disc sealing surfaces are overlaid with high-durability materials such as iron-base alloys, Co-base alloys, or carbide alloys to enhance longevity and ensure extended service life.
