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.
