Aura range of Instrument Valve
Manifolds cover 2 Valve, 3 Valve & 5 Valve Manifolds
The Manifolds are available in Carbon Steel (Zinc, Cadmium plated),
304 SS and 316 SS. Both Carbon Steel and Stainless Steel manifolds
are provided with Stainless Steel stems as standard to provide metal
to metal seating with tight shutoff. Other trim combinations are
available as options. All valve manifolds are provided with PTFE
packing as standard and graphite for high process temperatures.

Aura Two Valve Manifolds
The basic valve consists of two valves in a integral unit for isolation
and drain/calibration of pressure gauges, pressure switches, pressure
transmitters, differential pressure transmitters etc. Aura offers
two mounting arrangements:
- Integral type Direct mounting to an instrument
- Block & Bleed type and Angle type Line
mounting remote from instrument
Aura Three Valve Manifolds
Designed for use in conjunction with differential pressure transmitters.
The basic three Valve manifold consists of two process isolation
valves and one equalizing valve in a single compact unit.
Aura offers three mounting arrangements
- Separately mounted (R) type
Designed for remote line mounting to the instrument in any selected
position between the process line and the instrument.
- Single Flanged Integral (T) type
Designed for use with differential pressure transmitters that
utilise 2 1/8 (54 mm) center to center connection. On the process
side two 1/2" NPT connections are provided. Two 1/4"
NPT (F) purge connectors are standard with these units. 4 mounting
bolts and 2 PTFE gaskets for installation are provided as standard.
- Double Flanged Integral (H) type
These manifolds are flanged on both sides for mounting directly
to differential pressure transmitters having 2 1/8" (54 mm)
center to center connection. This model provides easy installation
and comes complete with 4 mounting bolts and 2 PTFE gaskets for
ready installation. Two 1/4" NPT (F) purge connectors are
standard with these units.
Aura Five Valve Manifolds
Designed to allow access to all valves in a single compact with
optimum ease of operation. The basic Five valve manifold consists
of two pressure isolation valves, two integral drain/vent valves
for purging and one equalizing valve.
These manifolds are available in two configurations:
- Separately mounted (R) type Designed for
remote line mounting to the instrument in any selected position
between the process line and he instrument.
- Single Flange Integral (T) type This model
is designed for direct mounting on a transmitter. The manifolds
mount directly to differential pressure transmitters having 2
1/8" (54 mm) center to center connections. Two 1/4"
NPT (F) purge connectors are standard with these units 4 mounting
bolts and 2 PTFE gaskets for installation are provided as standard.
The 'T' type manifold is available as a single block unit as a
unit with separately fitted drain valves.
Aura valve manifolds are manufactured under
strict quality control procedures and conform to international standards.
Standard inspection and testing procedures include:
- Visual Inspection for surface defects.
- Ultrasonic testing for integral defects of
raw material.
- Chemical analysis of raw materials.
- Visual and Dimensional checks of parts and
sub-assemblies at various stages of manufacture.
- Hydrostatic pressure test for the pressure
required as per specification.
Aura also offers the following options:
- Co-planar construction
- Delrin soft seat.
- Material conforming to NACE MR-01-75
- Corrosion resistant materials
- Pipe mounting kit for mounting on 2"
NB pipe
- Various parts/assembles for manifolds to
meet customers specific requirements.
