AQ1500-M5: Precision Exhaust Valve, Guardian of System Efficiency and Cleanliness
2026-01-29
Product Positioning
The AQ1500-M5 is an ultra-compact miniature automatic exhaust valve, specifically designed for applications in confined spaces where efficient removal of residual air and prevention of gas backpressure are critical. Its applications include precision pneumatic circuits, compact cylinders, vacuum generators, and instrumentations. Featuring an M5 ultra-fine threaded interface, it serves as an invisible guardian against system “airlocks” and efficiency losses.
Core Highlights: Sensitive, Compact, Efficient
Sensitive Micro-Exhaust, Eliminates Air Resistance
Equipped with a precision spring-float or diaphragm mechanism, it is highly sensitive to trace amounts of air accumulating within the system. It automatically opens to exhaust air when air accumulates and seals tightly once the air is expelled. This effectively prevents pneumatic components from experiencing sluggish movement, creeping, or unstable output due to “air compression.”
Extremely Compact, Boundless Installation
Featuring an M5 x 0.8 ultra-fine metric threaded interface, its compact size resembles a nut. It can be easily installed in cylinder rodless end covers, solenoid valve exhaust ports, vacuum circuits, or any tiny interface requiring exhaust, occupying almost no additional space.
Check Valve with Throttling, Intelligent Control
Designed as a check valve structure, it allows gas to exhaust only from the system to the external environment, effectively preventing the ingress of external dust and liquids.
Some models integrate adjustable exhaust throttling functionality, enabling precise control of exhaust speed to achieve smooth and slow cylinder movements and avoid end-impact shocks.
Reliable Sealing, Media Compatibility
The valve seal is made of high-quality rubber (e.g., NBR), ensuring reliable sealing for both compressed air and vacuum after exhaust, with no leakage.
The body is constructed from brass or stainless steel, offering corrosion resistance and suitability for general industrial air supply environments.
Easy Maintenance, Plug-and-Play
Featuring a monolithic design, it requires no power supply or external control, truly functioning as “install-and-forget” for maintenance-free automatic operation.
When cleaning or replacement is needed, it can be easily unscrewed as a whole, ensuring minimal maintenance costs.
Summary: The System Optimization Expert That Solves Big Problems in a Small Package
Though small in size, the AQ1500-M5 exhaust valve plays a critical role in enhancing the response speed, motion stability, and energy efficiency of precision pneumatic systems. By automatically and sensitively eliminating harmful residual gases, it fundamentally optimizes circuit performance. Its value is particularly evident in miniaturized, highly integrated equipment with stringent space and weight requirements. Choosing the AQ1500-M5 means infusing your precision pneumatic system with smooth, reliable, and efficient performance at minimal cost and spatial expense, making it the smart choice for pursuing ultimate equipment performance.
