ASTM A105N Globe Valves, API 602, 2 IN, 600 LB, Bellows Seal

Key Specifications / Features

The ASTM A105N Globe Valves Supplier offers high-quality bellows sealed globe valves designed to meet API 602 standards. These 2-inch (DN50) forged carbon steel valves feature a bellows seal, ensuring leak-tight performance and protecting against fugitive emissions. Rated at Class 300 LB and PN50, they provide reliable flow control in various industrial applications. The valves come with raised face (RF) flanged ends for easy installation and manual operation for precise control.

Forged Steel Globe Valves are designed and manufactured in strict accordance with international standards such as API 602, ASME B16.34, and DIN 3202. They feature a compact yet exceptionally robust construction, making them ideal for high-pressure, high-temperature applications. An optional solid CoCr alloy wedge ensures low friction and extended service life. The packing rings are precompressed to 4000 psi, providing a reliable and high-integrity seal. In welded bonnet configurations, the bonnet is threaded and torqued to a precise value, with the body-bonnet joint strength-welded to deliver dual protection against leakage. The fully guided wedge design minimizes wear on seating surfaces. Optional features include double packing, leak-off connection, live-loading, and a packing blowout function for convenient removal and replacement of worn packing.
