+ GATE VALVE I CATEGORY                                                       — cast steel bolted bonnet type gate valve                                                                                                                                  — forged steel rising stem type      gate valve                                                                                                                                  — pressure sealed os&y type          gate valve                                                                                                                                                                                                                                                       



⌈DISTINCTIVE FEATURES⌋       □ Pressure Sealed Bonnet    ■ High Pressure Valve          □ High Temperature Valve    ■ Rising Stem OS&Y            □ Flexible Wedged Type      ■ ASME B16.34 Valves        □ API 6D & CE Certified

                                                        – MAIN CHARACTERISTICS –                                                                                                               □  The pressure sealed gate valves are designed in accordance with API600 and ASME B16.34 for high temperature and high pressure service, widely used in steam-generation station, industrial chemical plant and thermal power plant.      ■ Compared with bolted bonnet joint valves, the pressure sealed gate valves  Glofa made provides absolute reliable sealing of the bonnet joint, which are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.

– DESIGN ADVANTAGES –                                                                                                                     □ The pressure sealed gate valves is not only characterized as simple structure and reliable usage, but also able to create slight flexible deformation to compensate the deviation of the sealing face angle generated during processing, thus improving the process performance.                                                                  ■ The seat and gate seal surface of Glofa’s pressure sealed gate valves are made over-lay with iron-base alloy or Co-base alloy or carbide alloy for long duration.
