english• Inclination angle of the pipeline.
The inclination angle is the responsibility of the installer andoperator and should correspond to the inclination angle of thepipeline. For the pipeline, we recommend the inclination angle
according to the valid ASME BPE.
• Self-drainage-angle for valve body: he self-drainage-angle (α) depends on the valve body size (diaT
phragm size) and the inner diameter of the port connection (DN).
 he self-drainage-angle is specified as a value on forged steelTvalve bodies (VS) and tube valve bodies (VP). (See “Fig. 2” and“Fig. 3”).
The marking on the port connection of valve bodies serves as anorientation aid (see “Fig. 25”). The marking must point upwards.
 he actual self-drainage-angle must be set with a suitable measT
uring tool.
