YQK-12 Marine Air Reducer For Starting Air Bottle & Pneumatic Control Pipeline
Product Spotlights
Shanghai Zhibang Valve Manufacture Co., Ltd is proud to present the YQK-12 Marine Air Reducer, a precision-engineered solution specifically designed for starting air bottles and pneumatic control pipelines in marine environments. Built with robust materials and tested under stringent quality standards, this air reducer ensures stable, accurate pressure reduction from high-pressure air sources to the required working levels, safeguarding downstream equipment and enhancing operational safety. With over 8 years of valve manufacturing experience and ISO9001 certification, we deliver products that stand up to the harshest marine conditions.
Key Features & Technical Specifications
- Stable Pressure Regulation: Maintains precise outlet pressure regardless of inlet fluctuations, ensuring consistent performance for pneumatic controls and starting air systems.
- Corrosion-Resistant Construction: Available in high-grade brass or stainless steel, with optional anti-corrosion coating for extended service life in saltwater environments.
- Wide Adjustable Range: Outlet pressure can be easily set from 0.1 to 10 bar via a lockable adjustment knob, with clear scale indication.
- High Flow Capacity: Optimized internal design minimizes pressure drop and supports high flow rates required for rapid air bottle charging.
- Compact & Lightweight: Space-saving design suitable for tight marine installations; weight ranges from 1.2 kg (1/4") to 8.5 kg (2").
- Multi-Connection Options: Threaded (NPT/BSP) or flanged ends available upon request, compatible with standard marine piping systems.
- Integrated Safety Features: Built-in relief valve and sintered bronze filter element protect downstream components from overpressure and contaminants.
- Certified Quality: Manufactured under ISO9001 quality management system, with 100% factory testing before shipment.

Frequently Asked Questions (FAQ)
-
Q: What is the typical application of the YQK-12 marine air reducer?
A: It is primarily used to reduce high-pressure air from starting air bottles (typically 30 bar) to a lower working pressure (e.g., 6–10 bar) for pneumatic control systems, engine starting valves, and other onboard air tools. -
Q: Can this reducer be used with gases other than air?
A: Yes, it is compatible with nitrogen, inert gases, and non-corrosive dry gases. For other media, please consult our technical team. -
Q: What materials are available for the valve body?
A: Standard options include brass (for general marine use) and stainless steel (for higher corrosion resistance). Custom materials can be arranged upon request. -
Q: Is the outlet pressure adjustable while the system is under pressure?
A: Yes, the adjustment knob can be turned under pressure, but for precise setting we recommend making adjustments when the downstream system is isolated. -
Q: What is the pressure drop across the reducer at rated flow?
A: The pressure drop is typically less than 0.5 bar at 50% of maximum flow capacity. Detailed flow curves are available in our technical datasheet. -
Q: Do you provide certification for marine classification societies (e.g., DNV, CCS, ABS)?
A: While our standard model is ISO9001 certified, we can assist with third-party inspection or additional certifications upon request and at extra cost. Please contact us for specific requirements. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment covering manufacturing defects. Extended warranty options are available. -
Q: How do I select the correct size for my application?
A: Size selection depends on flow rate, inlet pressure, and desired outlet pressure. Our technical support team can help you choose the right model based on your system parameters.
