10.3 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 so-
lution for your process.
