CARX Combination Air Release Valve （Anti-shock / nonslam）
Anti-Water Hammer Protection
Built-in anti-shock mechanism slows down air release during pipeline filling, effectively preventing water hammer damage in high-risk zones.
Triple Function Air Management
Combines large orifice air release, air intake, and small air discharge to ensure pressure balance throughout pipeline operation.
Corrosion-Resistant & Durable
Fusion-bonded epoxy coating (inside & outside), stainless steel float and anti-insect screen ensure excellent durability and corrosion resistance.
Low-Pressure Sealing & Full Bore Flow
Achieves tight sealing at low pressure (0.2 bar); full bore body design maximizes airflow capacity with minimal resistance.
Maintenance-Free Compact Design
No arms or levers – direct vertical float closure avoids vibration or fatigue. Smooth barrel guides float motion with integrated buffer.

- Application Conditions
Long-distance Water Transmission Mains
Ideal for urban or intercity transmission pipelines, especially in undulating terrains where air release and vacuum protection are essential.
Pump Station Discharge & Suction Pipelines
Protects against air lock and vacuum damage during pump start-up and shutdown cycles.
High Elevation Drop Pipelines / Mountainous Networks
Reduces the risk of surge and water hammer caused by sudden velocity changes in gravity-fed systems.
Urban Distribution Networks & High-Rise Buildings
Ensures reliable operation of vertical water supply lines in buildings by preventing air pockets.
Sewage & Reclaimed Water Pipelines (with anti-corrosion version)
Available in corrosion-resistant versions for use in wastewater or non-potable water applications.

Testing Process
From raw materials to finished products, NORITE maintains 100% testing coverage, ensuring that every valve and pump you receive is built to last — safe, stable, and globally certified.
Pressure Testing
Each valve undergoes rigorous pressure and hydrostatic testing prior to shipment to verify body strength, sealing integrity, and pressure stability—ensuring zero leakage and long-term reliability in field operation.
Torque and Functional Testing
Confirming operating performance and precision.
Cycle Life Testing
Simulating long-term use under real working conditions.
Coating & Corrosion Resistance Testing
Validating surface protection and durability.
Dimensional & Material Analysis
Using spectrometers and coordinate measuring machines (CMM) for accuracy.
Traceability - Unique product code
Each product leaving our factory is accompanied by a full inspection report and a unique serial number, enabling full traceability and lifetime quality tracking.
Real Project Cases

North South Interconnector Pipeline – Australia
- North South Interconnector Pipeline
- Working conditions/Challenges:
The main water supply pipeline (diameter 250-800 mm, length approximately 12 km, terrain ranging from -45 m to +66 m) has a large terrain difference along the pipeline and has experienced water hammer damage incidents.
- The type of equipment adopted:
Our combined exhaust valve was selected for this large-diameter water transmission pipeline and pumping station. Our product features large-volume exhaust, large air intake, and anti-water hammer protection functions.
Key indicators: TAfter the combined air valve is correctly installed, it can significantly reduce the peak impact pressure and protect the pipeline and equipment.
