  • Description

  • Quality Assurance

The valve body shall adopt a one-piece U-section design and a concentric disc and seat configuration to accommodate  2" - 56" of piping insulation, have flange holes drilled in accordance with international flange standards, and be equipped with a non-corrosive bushing and self-adjusting stem seal. Flange locating holes shall be provided on U-section bodies to facilitate quick and precise alignment during valve installation. The edge and hub of the valve disc on metal discs shall be spherically machined and hand polished for minimum torque and maximum sealing capability. The disc-to-stem connection shall be an internal square design without any possible leak paths in the disc-to-stem connection. External disc-to-stem connections such as screws or pins are prohibited. The valve seat shall have a tongue-and-groove design. The seat shall completely encapsulate the body, isolating the body from the line media, and no flange gaskets shall be necessary. The U-section valve shall be rated for bubble-tight shut-off in bidirectional service at 16 Bar for sizes 2" - 12" (50mm - 300mm) and at 10 Bar for sizes 14" - 56" (350mm - 1400mm). The valve shall be tested for tight shut-off at 110% of the rated pressure.
