Remote Mounting 5 RM3
Model 5 RM3 carries two process isolation valves, one equaliser valve and two drain / vent valves on separate connections, in one compact block, for remote mounting away from the differential pressure instrument on tube or pipe impulse lines.
It shares 5 RM1's valve set and separate drain connections; the body form differs, so choose between them on how the manifold has to sit rather than on what it does.
Dimensions are for the standard 54 mm (2 1/8 in) instrument connection centre distance, which is what most instruments use. The manifold is also made for other centre distances — 55 mm, 56 mm and 57 mm — with dimensions to suit; ask for those. Process and instrument connections are 1/2" NPT (F) and the drain / vent is 1/4" NPT (F). A test port on the process side with a plug is available as an option. Two mounting bolts to IS 1364-1960 are supplied.
