Frequently Asked Questions
What is a non-return valve and why is it important?
A non-return valve only allows air to flow in one direction, preventing backflow into your compressor system. This helps maintain pressure stability and protects compressor components from damage caused by reverse flow
What sizes of Pilot Air non-return valves are available?
Pilot Air offers multiple sizes, including ½″, ¾″, 1″, and 1 ¼″ BSP configurations (such as 12X12CV, 34x34CV, 1x1CV, 1.1/4X1CV) to suit different compressor receivers and piping setups. You can find the full range on the Non-Return Valve Spares page.
Are these non-return valves built for Australian conditions?
Yes — our non-return valves are made in Italy to high quality standards, stocked locally in Sydney, and designed to endure heat, dust, and frequent usage seen in Australian workshops and industrial environments.
How do I choose the right non-return valve for my compressor system?
To pick the correct valve, match the valve size (BSP), ensure compatibility with your receiver’s outlet or inlet size, and confirm it can handle your working pressure. Details for sizing and model options are provided on the Non-Return Valve Spares page.
Can I get spare non-return valves quickly if one fails?
Yes — Pilot Air maintains stock of genuine non-return valves in our Service & Spares division in Auburn, Sydney. You can request a quote or replacement via the Non-Return Valve Spares page to ensure minimal downtime.
Pilot Air Reviews
We have a growing manufacturing business and our air supply needed to be upgraded to deliver to a clean volume of air to specific machines and mainly our spray booth. 3 Months ago the team at Pilot Air evaluated our requirement and delivered an excellent solution, we have had time to run the system for a considerable time and found it to be excellent. Also Australian Manufactured to boot. Very Happy.

My husband recently bought a second hand Trademaster 12 air compressor in need of some maintenance. He took it to the Silverwater servicing centre with no prior arrangement. The staff were polite, obliging, and eager to help, and he was impressed with the service provided. Well done Pilot Air!
