ASTM A351 CF8C Gate Valve, API 600, 16 IN, CL2500, PSB, BW

Product Name: Stainless Steel Gate Valve, Pressure Seal Bonnet
Design Standard: API 600
Body Material: ASTM A351 CF8C
Size: 16 Inch, DN400
Pressure: Class 2500 LB, PN420
End Connection: BW
Operation: Gearbox

Pressure seal gate valves are designed in accordance with API 600 and ASME B16.34 for high-temperature and high-pressure applications, making them widely used in fossil fuel power plants. Compared to bolted bonnet joint valves, they offer absolutely reliable sealing at the bonnet joint, ensuring a more compact, rigid, and cost-effective solution for high-temperature and high-pressure service.

Product Features

» Design and Material Selection: Pressure Seal Gate Valves are designed for excellent service in steam-generation stations, industrial chemical plants, and thermal power plants. They are available in Cast Steel and Forged Steel body designs, providing a versatile range of options for various application requirements.
» Reliable Performance: These valves are known for their simple structure and reliable operation, making them ideal for demanding high-temperature and high-pressure environments. They are designed to deliver optimal sealing performance over extended periods.
» Compensation for Sealing Face Deviation: The valves are capable of slight flexible deformation to compensate for any deviation in the sealing face angle that may occur during processing. This feature improves overall sealing integrity and enhances process performance.
» Durability and Longevity: The seat and gate disc sealing surfaces are overlaid with iron-base alloy, Co-base alloy, or carbide alloy, ensuring superior durability and extended service life, even in harsh operating conditions.
