Butt-welding valve
Face-to-face, centre-to-face, end-to-end and centre-to-end dimensions of valvesButtwelding valvesSubject content and scope of application
This standard specifies the structural length and limit deviation of butt-welding valves. GB/T 15188.1.-
This standard applies to butt-welding gate valves, stop valves, throttle valves, ball valves, plug valves and check valves with nominal pressure PN1.0~～42.0MPa and nominal diameter DN6~900mm. 2 Structural length and limit deviation
The basic series of valve structural length is shown in Table 1, the structural length 1 is shown in the figure and Tables 2 to 6, and the structural length limit deviation is shown in Table 7. Approved by the State Bureau of Technical Supervision on August 29, 1994, implemented on July 1, 1995
