Unidirectional Fluid Control Valve

This product is a two-end M22×1.5 external thread tubular one-way valve (check valve) made by Xiamen Jiedeng Machinery Co., Ltd., a expert and supplier in commercial vehicle valves from China.

The valve body adopts an aluminum alloy lightweight structure. The external part is a standard external hexagon with a diameter of 32mm, and the total length is approximately 72mm. It is convenient for wrench installation and integration with the pipeline.

As a unidirectional fluid control valve for the air tank, this product can be used in the air circuit, oil circuit to prevent reverse flow, pressure retention, and flow interruption protection. It is commonly seen in commercial vehicle air braking, construction machinery, air compressor pipelines, air source manager kits, and other scenarios.

Structure and Principle

1. Cone valve core + spring seal, allowing only forward flow and prohibiting reverse flow. It has a low opening pressure, low flow resistance, and excellent sealing performance.
2. Hexagonal body has high strength, fast heat dissipation, corrosion resistance, and light weight. It is suitable for pneumatic/hydraulic/oil/gas medium systems and is a stable single-phase fluid control valve.

Specification for One-way fluid control valve for air tank

1. Interface: Both ends have M22×1.5 external threads
2. Dimensions: Hexagon head S = 32mm, total length ≈ 72mm
3. Materials: Valve body - Aluminum alloy; Valve core / Spring - Stainless steel
4. Applications: Pneumatic braking, hydraulic oil circuit, air tank system, etc.

Application Scenario

1. The gas storage tanks need to be pressurized separately to prevent a leak in one circuit from causing the air pressure in the entire vehicle to drop instantly.
2. When the air pump inflates the gas storage tanks, it is necessary to prevent the gas from flowing back to the air compressor after parking, which could result in air pressure loss.
3. The brake valve and the air path module need to maintain pressure to avoid the pressure in the braking system dropping and causing weak braking.
4. In multi-circuit air paths, it is necessary to isolate different air paths to prevent mutual interference and cross-contamination of pressure.
5. When repairing the air path or installing an air intake connector, the gas storage tank fluid control valve can be used to prevent accidental pressure loss, ensuring driving safety.
