Manifolds
Three-Valve T-Type
Designed for direct mounting onto standard differential pressure transmitters, in the "T" pattern. The block carries two main process isolation valves and one equalising valve, with the process side screwed and the manifold landing directly on the instrument.
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 drain / vent is 1/4" NPT (F). Two PTFE seal rings and four 7/16" UNF high-tensile steel mounting bolts are available on request. 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.
