A university research laboratory was developing a high-pressure test rig to investigate the performance of advanced materials under extreme pressure conditions. The system was designed to circulate inert gases at pressures approaching 6,000 psi while maintaining precise control over flow and ensuring the safety of researchers.
The laboratory required a compact, reliable isolation valve capable of frequent operation without compromising sealing performance or introducing contamination into the test system.
The Challenge
The research team identified several key requirements:
- Safe isolation of high-pressure gas circuits.
- Leak-tight performance during long-duration experiments.
- Compatibility with stainless steel instrumentation tubing.
- Resistance to corrosion from laboratory environments.
- Simple maintenance with minimal downtime.
- A compact design suitable for installation within a confined instrumentation panel.
As experiments involved valuable prototypes and sensitive measurement equipment, even minor leakage or pressure loss could invalidate test results.
The Solution
The laboratory selected a Parker HPBWB16ALPFS high-pressure ball valve as the primary isolation valve within the gas delivery system.
The valve's stainless steel construction provided excellent corrosion resistance, while its quarter-turn operation enabled rapid isolation during both normal operation and emergency shutdown procedures. Its compression tube end connections allowed direct integration with the existing 1-inch stainless steel instrumentation tubing without additional adapters.
The fire-safe design also aligned with the laboratory's risk assessment requirements, providing an additional level of protection for high-energy test equipment.
Results
Following installation, the laboratory reported several operational improvements:
- Stable pressure control throughout extended testing cycles.
- Reliable bubble-tight shut-off that prevented gas leakage during overnight experiments.
- Faster maintenance, allowing individual sections of the rig to be isolated without depressurising the complete system.
- Reduced installation time due to compatibility with existing instrumentation fittings.
- Increased confidence in experimental repeatability through consistent valve performance.
The valve has since become the laboratory's preferred specification for new high-pressure test rigs and prototype research equipment.
Conclusion
The Parker HPBWB16ALPFS proved to be an effective solution for demanding laboratory applications requiring dependable high-pressure isolation. Its robust construction, reliable sealing performance and ease of integration helped improve both the safety and efficiency of the research facility while supporting accurate, repeatable experimental results.
