Linear and diameter dimensions are in mm; weights are in kg. Pressure bands are in MPa (1 MPa = 10 bar). Height and length datums follow the drawing. Thread designations and ISO mounting codes are not linear dimensions. PN40 threaded source arrangement, DN10, DN15, DN25, DN40 and DN50. DN20 and DN32 dimensions are not supplied. The source 2-M column is reproduced as a drawing value; it does not identify the BSP/NPT thread designation. Use the approved order drawing for installation and fabrication.

| Dimension data | Reference table and drawing: DN10, DN15, DN25, DN40, DN50. Dimensions and connection reference. |
| Installation drawing | Confirm BSP or NPT, male/female ends, thread sizes, engagement, end-to-end length and installation clearance. |
| Pressure-temperature rating | Obtain the allowable-pressure table or curve versus temperature for the selected body, seat and seals, including minimum and maximum design temperature. Nominal rating and a family temperature range do not define this curve. |
Nominal pressure class, temperature range and relief set pressure are separate specifications. Confirm the allowable pressure at the design temperature for the selected construction.
