OXYCHECK - High Pressure Gas System Components

OXYCHECK is an Australian company dedicated to the design and manufacture of safe and reliable oxygen compatible and high-pressure gas system components. Our extensive experience in the safe analysis, design, maintenance and operation of oxygen and air systems, coupled with our active research programmes into the flammability and sensitivity of metallic and non-metallic materials provides an unrivalled level of expertise used to address all issues relevant to these systems.

OC-001 CHECK / FILL VALVE ASSEMBLY

One of OXYCHECK's patent pending designs is the OC-001 check / fill valve assembly. Its operating pressure can be user specified, its proof pressure is 3,750psi (hydrostatically tested to 1.5 x MAWP) and its burst pressure 5,000psi (2 x MAWP). Its operating temperature is -57°C to +95°C.

The OC-001 check / fill valve assembly's mean internal leakage rate is 0scc/min, and its cracking pressure can also be user specified.

The flow rates of the OC-001 check / fill valve assembly are (to +/-10%):

• 30L/min at 48psi
• 100L/min at 90psi
• 150L/min at 115psi
• 200L/min at 135psi

Tested for endurance to >2,000 cycles at 200L/min, evaluated at MAWP, the OC-001 check / fill valve assembly is made of monel K-500TM, monel 400TM, nickel 200TM, brass and synchronised sapphire (Al2O3). A 7μm sintered bronze 'witches cap' is available for filtration, and the end connections are user specified.

The OC-001 check / fill valve assembly provides:

• Fire-safe reliable performance with excellent flow and sealing characteristics
• Customised housings and end configurations to suit all aircraft and industrial applications
• Optional 10μm sintered bronze filtration
• Engineered, tested and quality controlled to strict military specifications
• Multiple check valve units used in series / parallel configuration for operating in a manifold system

CUSTOMISED GAS SYSTEM COMPONENTS

Utilising the latest technologies available and the world's best knowledge base throughout every stage of product development, manufacture and utilisation, our patent pending check-valve design can be adapted to meet all user-defined requirements for gas check operations, including high-pressure fill valves, in-line check valves, manifold check or control valves, excess flow valves, relief valves and any other application where accurate flow control and fire safety are of concern.

All designs can incorporate appropriate filtration as required in specific applications. Ask us how we can meet all of your current and future systems' requirements

ADVANTAGES OF OUR GAS SYSTEM COMPONENTS

OXYCHECK's unique, patent-pending designs provide:

• Fire safety – we have world-recognised expertise in material selections and engineering designs for oxygen-enriched environments
• High performance – OXYCHECK products deliver high-endurance life combined with excellent flow and sealing characteristics
• Cost-effectiveness – our systems are supplied cleaned, tested and ready to attach to an aircraft, with full supporting documentation

OXYCHECK engineers are always ready to assist with after sales-enquiries and system monitoring, and can provide complete Oxygen Fire Hazards and Risk Assessments (OFHRAs) of your system.

GAS SYSTEM COMPONENT DESIGN AND MANUFACTURE

With all devices developed using advanced 3-D CAD software and Finite Element Analysis (FEA), every aspect of the design and manufacture of our gas system components is carefully assessed to ensure all material, functional and dimensional requirements are met.

This ensures that safety and functionality features – including strength, capability, tolerances, filtration requirements, natural frequencies and flow requirements – are all demonstrated and incorporated into every device.

Each design prototype then has all parameters rigorously verified in our world-class test and production facility to ensure functionality and conformance to user requirements. Additionally, a formal oxygen hazards and fire risk analysis is performed on every assembly and sub-component.

All products meet or exceed all recommendations or test requirements as specified in relevant ASTM, AS, ISO, CGA or NASA/ESA standards or processes, and are cleaned in accordance to these and / or MIL-SPECs. This approach is used in all product lines, including our high-pressure oxygen check valves, high-pressure oxygen fill valves and high-pressure oxygen relief valves.
