Product
H-Type
Flanged on both sides with the drain port on one side and an optional test port at the bottom — mounts direct or remote.
Manifolds
H-Type
Designed for direct or remote mounting of differential pressure transmitters. For remote mounting, two oval / kidney flanges connect the process pipe to the manifold block. The block carries five valves: two main valves for process isolation, one for venting and two for equalising.
The drain port is on one side, with an optional test port at the bottom.
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 both flanged and the drain / vent is 1/4" NPT (F). A mounting bracket with U bolts and the kit to fit it to a 2" NB stanchion pipe stand or a wall is ordered separately. Four mounting bolts to IS 1364-1960 and two PTFE or Viton interface seals are supplied.
