    Frequently asked questions

    What is a safety relief valve and why is it essential?

    A safety relief valve automatically releases air if the receiver pressure exceeds safe limits (factory-set at 11 Bar), protecting both your equipment and operators in compliance with AS1271.

    What sizes and flow rates are available in the Safety Relief Valve range?

    The safety relief valves come in sizes from ¼″ BSP to 1″ BSP, with flow capacities reaching up to 10,700 L/min, ensuring suitability for small workshops through to heavy industry.

    Are these safety relief valves built for Australian operating conditions?

    Yes — the Pilot Air valves are USA-made, set at 11 Bar, and rated to AS1271 Class B, giving reliable performance in Sydney’s demanding heat, dust and long duty cycles.

    How do I know which relief valve is right for my compressor or receiver?

    The right safety relief valve depends on your air receiver’s volume, maximum working pressure, and outlet size. Choosing a valve that meets or exceeds your system’s specs ensures both safety and compliance.

    Where can I buy replacement safety relief valves or related parts in Sydney?

    You can order directly from the Safety Relief Valves product page or through Pilot Air’s Air Compressor Spares section, with local stock available from the Auburn Service & Spares facility.
