Pressure Seal Globe Valves are meticulously designed and manufactured in strict accordance with international standards such as API 602, ASME B16.34, DIN3202, or their equivalents. These valves feature a compact yet extremely robust design, making them ideal 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 (through the body, bonnet threads, and strength-weld). The fully guided wedge reduces wear on seating surfaces. 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 fine processing, forged steel materials exhibit excellent corrosion resistance, making them suitable for a variety of corrosive media and thereby extending the service life of valves.
» Forged steel globe valves are typically designed to be 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.
