Pressure Seal Bonnet Globe Valves, A105N, 1-1/2 Inch, CL1500

The Pressure Seal Bonnet Globe Valves Factory specializes in producing high-performance globe valves designed to meet API 602 standards. These valves are crafted from forged carbon steel (ASTM A105N), ensuring robustness and reliability. With a 1-1/2 inch (DN40) size and a pressure rating of 1500 LB (PN250), they are suitable for demanding industrial applications. The valves feature pressure seal bonnet technology, which enhances sealing performance under high-pressure conditions.

Pressure Seal Globe Valves are meticulously designed and manufactured in strict compliance with international standards such as API 602, ASME B16.34, DIN 3202, or equivalent. These valves feature a compact yet extremely robust design, making them suitable for high-pressure and high-temperature applications. The optional solid CoCr alloy wedge ensures low friction and extended service life. The packing rings are precompressed to 4000 psi, providing a highly reliable seal. For welded bonnet valves, the bonnet is threaded in and torqued to a precisely engineered torque value, and the body-bonnet joint is strength-welded, offering dual protection against leakage (body, bonnet threads, and strength-weld). The fully guided wedge reduces wear on seating surfaces. Additionally, optional designs are available with double packing, leak-off connections, live-loading, and a packing blowout feature for easy removal of old packing.

Product Features

After undergoing fine processing, forged steel materials exhibit excellent corrosion resistance, making them well-suited for use in various corrosive media and thereby extending the service life of valves. Additionally, forged steel globe valves are typically designed to be more compact, featuring a smaller volume and occupying less space. This makes them easy to install and use, particularly in working conditions where space is limited.
