ABB Electromagnetic Flowmeter Selection Guide Choosing the Right ABB Electromagnetic...
At Adyaa Engineering, we understand that a Pressure Relief Valve (PRV) is the final line of defence between safe operation and a catastrophic event. As a leading Calibration Company in Australia, our mission is to provide industry-leading calibration, maintenance, and certification services that ensure your assets remain compliant, your personnel remain safe, and your operations remain uninterrupted. With decades of combined technical expertise, we specialize in testing and overhauling safety valves across the oil and gas, power generation, chemical, and manufacturing sectors.
“A relief valve is only as good as its last test. We ensure that when your system hits the limit, your safety measures perform exactly as designed.
Our facilities utilize high-precision digital logging and NATA/ISO traceable equipment to ensure every “set pressure” and “reseat” is documented with mathematical certainty.
Whether through our In-Site (In-Line) Testing technology for Onsite Calibration Services in Australia or our rapid-turnaround workshop services for Offsite Calibration Services in Australia, we focus on reducing your Mean Time to Repair (MTTR).
We don’t just test; we certify. Every valve serviced by us receives a comprehensive digital report meeting API 527 and ASME standards, providing you with a transparent audit trail for insurance and safety inspectors.
From the initial “As-Found” testing to precision lapping and final “Green Tag” certification, we handle the entire maintenance lifecycle in-house.









Highlight the breadth of your services to show that you are a “one-stop shop” for pressure management, providing comprehensive
Calibration Services in Melbourne, Sydney, Brisbane, Australia:-
Trust is built on certifications. Ensure this industry standards are front and centre:
Visual check for corrosion, pitting, and mechanical damage.
As-Received” pop test to document performance before servicing.
Complete disassembly, cleaning (including Oxygen Cleaning), and parts replacement.
In-house lapping of nozzles and discs to restore OEM-spec finishes.
Issuing traceable calibration certificates and “green tag” service labels.
For many industries, the biggest “pain point” is shipping heavy valves. Highlight your logistics:
Mobile Service Centres: Fully equipped 20ft or 40ft containerized workshops that travel to the site.
Turnaround/Shutdown Support: 24/7 dedicated teams to handle high-volume valve testing during scheduled outages.
Asset Management: Online portals where clients can download their test reports and track upcoming calibration dates.
We don’t believe in “one size fits all.” Our technicians are trained to handle a diverse range of media—including steam, air, gas, and liquid—adjusting our testing protocols to match the specific thermodynamics of your process environment. By combining traditional craftsmanship (like hand-lapping valve seats) with modern diagnostic technology, we extend the service life of your critical infrastructure.

Costs vary based on equipment type, testing medium, and whether you need Onsite Calibration Services or workshop testing. Contact us for a precise quote.
While we specialize in industrial valve Calibration Services, scale calibration involves using certified test weights to verify accuracy against national trade measurement standards.
It is the process of testing, adjusting, and certifying an instrument (like a pressure relief valve) against a highly accurate standard to ensure safety and regulatory compliance.
