SKU: 0306R
Traditional in-line integral manifold that screws factory-direct to an in-line pressure transmitter (3051T / 3051HT / 2051T) or pressure gauge via NPT threads. Block-and-bleed, two-valve, or ASME B31-compliant two-valve configurations. 316 SST workhorse plus Alloy C-276 / Alloy 400 / Alloy 625 / Super Duplex SST options for aggressive service. Pairs with the R306 Enhanced (Pressure-Lock) variant for sites that need a rebuildable valve seat.

Body / bonnet / stem / tip material. 316 SST is the workhorse; Alloy C-276 / 400 / 625 / Super Duplex are for aggressive media.
How the manifold mates to the process pipe on one side and the transmitter on the other. AA (½ NPT male × ½ NPT male) is the workhorse for in-line transmitters; BA flips the process side to female NPT. AW/BW variants connect to Rosemount Pressure Gauges instead of transmitters.
Rosemount is configurator-heavy and quote-only — Valley Instrument verifies option compatibility, lead time, and pricing before confirming your order.

2-, 3-, or 5-valve conventional manifold for inline mounting between the process and the transmitter. Traditional or wafer style, 316 SST / Alloy 400 / CS body. Configured to assemble factory-direct to a 2051 or 3051 transmitter (selected via S6 / A12 / A22 process connection on the transmitter).

2-, 3-, or 5-valve integral manifold that bolts factory-direct to the Coplanar transmitter flange (3051C, 2051C, or 3051S). 316 SST or Alloy C-276 body with PTFE or graphite-based packing. Selected via the S5 process-connection code on the host transmitter. Pairs with the R305 Enhanced (Pressure-Lock) variant for sites that need the rebuildable valve seat.

Enhanced Integral Manifold with the Pressure-Lock valve and two-piece stem design — exclusive to the R305/R306 lines. 2-, 3-, or 5-valve Coplanar mount that bolts directly to a 3051C, 2051C, or 3051S transmitter. 316/316L SST body only with ½-14 NPT female process connections; PTFE or graphite packing; optional NACE-compliant wetted materials and P2 cleaning for special services.
