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