Frequently Asked Questions
What are unloader valves and when are they used?
Unloader valves release pressure from the receiver when there’s no mechanism to automatically stop the compressor, making them essential for petrol or diesel-powered compressor setups.
Which models of unloader valves does Pilot Air stock and what do they suit?
The unloader valve range includes models such as VMC12 (½″), VMC34 (¾″), and VMC114 (1¼″), which are compatible with compressors like the K17P, K25P, K30P, K17D, and K25D
Are these unloader valves built for Australian conditions?
Yes — Pilot Air unloader valves are USA-made and stocked locally in Sydney, designed to withstand Australia’s heat, dust, and the heavy-duty cycles typical of industrial environments.
How do unloader valves help protect my compressor?
By venting excess pressure when the compressor cannot shut off automatically, unloader valves reduce wear, improve safety, and prevent overpressure damage.
How can I get spare unloader valves quickly in Sydney or other Australian states?
Genuine unloader valve spares are stocked at Pilot Air’s Service & Spares Division in Auburn and Silverwater. You can request a quote or order replacements directly through the product page for fast supply across Australia.
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!
