Valve configuration
Block-and-bleed
The block-and-bleed configuration is available on the
Romount 306 Manifold for u with in-line gage and absolute pressure transmitters. A single isolate valve provides instrument isolation and a bleed screw provides drain/vent capabilities.
Romount 306 Manifold
Two-valve
The 2-valve configuration is available on Romount 305, 306, and 304 Manifolds for u with absolute and gage pressure transmitters. An isolate valve provides instrument isolation and a drain/vent valve allows venting, draining, or calibration.
Romount 305 and 306 Manifolds
Romount 304 Manifold
Three-valve
The 3-valve configuration is available on Romount 305 and 304 Manifolds for u with differential pressure and multi-variable transmitters. Two isolate valves provide instrument isolation, and one equalize valve is positioned between the high and low process connections.

Note
Vent ports receive plastic caps to protect threaded connections unless otherwi noted.
Note
Plugged connections receive 1/4-in. NPT plugs unless otherwi
noted.

Five-valve
ztdThe 5-valve configuration is available on Romount 305 and 304 Manifolds for u with differential pressure and multivariable transmitters. Two isolate valves provide instrument isolation and one equalize valve is positioned between the high and low process connections. In addition, two drain/vent valves allow for controlled venting, 100 percent capture of vented or drained process, and simplified in-process calibration capability.
Romount 305 Manifolds and 304 (Wafer)
Five-valve natural gas
The 5-valve natural gas configuration is available on the Romount 305 and 304 Manifolds for u with differential pressure and multivariable transmitters. Two isolate valves provide instrument isolation and a single drain/vent valve allows for controlled venting, 100 percent capture of vented or drained process, and simplified in-process calibration capability. In addition, two equalize valves provide extra protection from leaking to ensure DP signal integrity.
⏹“NG” option includes wide handle pattern and soft ats for ea of u as well as a larger bore to reduce plugging Romount 305 Manifolds and 304 (Traditional)
