Emerson Anderson Greenwood M4TL User Manual

ANDERSON GREENWOOD M4TL LIQUID LEVEL MANIFOLDS

A single-flanged, two-valve manifold consisting of two block valves with no
equalizer passage suitable for pressures up to 6000 psig (414 barg)

GENERAL APPLICATION

The manifold is designed for direct mounting to
P-style differential pressure transmitters in
liquid level service on pressurized vessels.

TECHNICAL DATA

Materials: CS, SS, Hastelloy
Seats: Metal or soft
Connections: ½” NPT
Pressure (max.): 6000 psig (414 barg)
Temperature (max.): 1000°F (538°C)

FEATURES

• Cost savings of 20-30% when manifolding
instruments by eliminating several parts used
in conventional methods of ‘piping up’.

• Compact design requires minimum space for
operation and installation.

• Free-swivelling ball end stems ensure
bubble-tight valve closure without seat
galling.

• Easy instrument removal due to direct bolting
to the manifold. Signal lines, purge lines,
etc. are left undisturbed, facilitating repairs,
service and calibration.

• Immediate installation with AGCO Mount as
the manifold, steam block, bracket and all
associated piping can be installed without the
instrument at the time of plant construction.

• Secure mounting ensured by the AGCO
Mount. Instrument piping stability is
enhanced when supported directly by the pipe
stand through the manifold.

• All packing is below stem threads,
body-to-bonnet seal is below the threads
minimizing process fluid corrosion.

• Reduced chance of instrument damage.
With the AGCO Mount, the instrument can be
warehoused safely until final ‘loop’ checkout.
