WARNING
WARNING
WARNING
1 Refer to the VDI 2035
Guideline for recommended proper water treatment.
2 In steam
applications, install the valve with the stem horizontal to the
piping and wrap the valve and piping with insulation.
3 Rangeability is
defined as the ratio of maximum controllable flow to minimum
controllable flow.
