11. ISOLATION VALVE WITH RETRACTION UNIT (HIMP-2 AND HIMP-3)
Retraction Unit HIMP-2 and Retraction Unit HIMP-3 are used for safe removal of a K-Patents Process
Refractometer from a process line when under full process flow and pressure. Typical use is for continuous
processes with infrequent shutdowns and large pipe sizes, diameter 125 mm (5") or above e.g. in wood
pulp industry. For smaller pipe sizes (3" or 4") consult the K-Patents factory to find the best solution for
your process.
