Instrumentation Manifold Valves

Abdex supplies a comprehensive range of instrumentation valve manifolds designed for precise control, isolation, and venting in pressure measurement systems. Whether you’re working with pressure gauges, transmitters, or switches, our manifolds provide a safe and efficient interface between process and instrumentation.

Available in 2, 3, and 5 valve configurations, each manifold is engineered to meet the demands of high-pressure and high-temperature environments. The range includes:

  •      2 Valve Manifolds for isolation and venting—ideal for static pressure and gauge applications.
  •      3 Valve Manifolds featuring dual isolation and equalisation for differential pressure transmitters.
  •      5 Valve Manifolds that add two equalising and one vent valve for full system control and calibration flexibility.

Constructed from premium materials like 316 stainless steel, Monel, Duplex, Inconel, and more, our valve manifolds are designed for long-term performance and resistance to corrosion, vibration, and thermal stress. Pressure ratings are available up to 10,000 psi, with various end connection types, vent port options, and mounting configurations to suit both direct and remote installations.

All instrumentation valve manifolds include essential safety and usability features such as anti-rotational cam locking, non-rotating valve tips, back sealing, and multi-ring packings. Optional features like lockable vents, handwheel operation, and anti-tamper heads allow you to tailor each unit to your application’s requirements.

Whether you’re commissioning a new system or upgrading existing setups, Abdex instrumentation manifolds offer reliable, field-proven performance trusted in Oil & Gas, chemical processing, and industrial applications across Australia and beyond.
