Direct Mounting DM 2
Flanged body with the valves on three sides and a screwed process connection — DM 1's alternative where the handles need separating.

Direct Mounting DM 2
Designed for direct mounting onto standard differential pressure transmitters. Like DM 1 it carries two main process isolation valves and one equalising valve, but the body is flanged and the valves are taken out on three sides rather than all off the top, which separates the handles where DM 1's top cluster would be awkward.
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.
The process connection is 1/2" NPT (F) and the instrument connection is flanged. A drain port on the instrument side with a drain plug is available as an option, which takes the 64 mm dimension to 82 mm, as is a test port on the process side with a plug. Four mounting bolts to IS 1364-1960 and two PTFE or Viton interface seals are supplied.
