GLOBE 3 WAY CONTROL VALVE MIC – 241

INTRODUCTION

MicroSet 3 way control valves are used to combine two flows or to divert one flow into two outlets. They are designed to replace and perform the functions of two single ported control valves acting in opposite directions, in converging or diverging liquid flow. They can be used to control the circulation of water, oil, sea water or other liquid in heating or cooling applications involving heat exchanger bypass control.They can also be used in blending systems and on-off selector systems.
