GB/T 11698-2008 Metal valves for use in marine flanged pipe systems—Face-to-face and center-to-face dimensions
Abstract
This standard specifies the structural length and its limit deviations of metal valves with flange connections used in marine applications. This standard applies to marine piping systems with a nominal pressure range of 0.25 MPa to 4.0 MPa in the PN series, and 125 pounds to 300 pounds in the CLASS series; the flange connection dimensions and sealing surfaces comply with the design and specifications of metal valves in GB/T 2501, ASME B16.5, and ASME B16.47. For metal valves with other nominal pressures or flange connection dimensions not included in this standard, the structural length can be referenced to those of similar pressure levels for implementation.
