Integral Flanged Gate Valve, API 602, A105N, 2 Inch, 150 LB

Key Specifications / Features

The Integral Flanged Gate Valve Manufacturer offers a high-quality Forged Steel Gate Valve designed to meet API 602 and ASTM A105N standards. This 2-inch (DN50) valve features a Class 150 LB (PN20) pressure rating, ensuring reliability in medium-pressure applications. The welded bonnet design enhances durability, while the reduced bore optimizes flow control. Integral flanged ends provide a secure connection, making this valve ideal for various industrial piping systems.

Forged Steel Gate Valves are 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 to provide a high-integrity seal. For welded bonnet valves, the bonnet is threaded in and torqued to an 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. Optional designs are available with double packing, leak-off connection, live-loading, and a packing blowout feature for easy removal of old packing.
