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