SCUBA Pressure Cylinder Valve plays a crucial role in ensuring safe and efficient air delivery in underwater breathing systems and self-contained breathing apparatus units. Because it controls the on/off functionality and regulates the high-pressure air flow, it becomes one of the most essential safety components in any pressurized cylinder setup. Furthermore, its integrated safety features protect users from risks associated with over-pressurization, making it ideal for diving, firefighting, emergency rescue, and industrial safety environments.
Overview of the SCUBA Pressure Cylinder Valve
This high-strength cylinder valve functions as the primary switching mechanism for compressed air cylinders. It includes a built-in over-pressure safety burst system that activates automatically when the internal pressure exceeds 37 MPa. As a result, the protective burst disc releases excess pressure quickly and prevents dangerous cylinder failure. Additionally, the valve connects securely to both the cylinder body and the pressure regulator, ensuring stable air output under demanding conditions.
The valve uses a male M18 × 1.5 thread on the cylinder-side connection, while the regulator-side uses a G5/8 female thread with 14 TPI. These widely used thread standards allow seamless compatibility with many breathing air systems.

Key Features of the SCUBA Pressure Cylinder Valve
1. High-Pressure Performance
The valve supports a working pressure of 30 MPa, which ensures reliable airflow regulation even in demanding environments. Moreover, the strong internal passage allows a stable air discharge for emergency or continuous breathing applications.
2. Integrated Over-Pressure Protection
Its safety burst mechanism activates between 37–45 MPa, offering immediate relief when internal pressure increases beyond the safe limit. This feature significantly reduces the risk of accidents.
3. Durable Brass Construction
The valve body uses high-quality brass, offering excellent corrosion resistance, long-term stability, and durability under harsh conditions such as saltwater exposure or high humidity.
4. Versatile Thread Compatibility
Because it uses the common M18 × 1.5 cylinder thread and the G5/8 outlet thread, the valve connects easily to a wide range of breathing systems, regulators, and high-pressure cylinders.
5. Reliable First-Stage Control
This valve acts as the primary control point on the cylinder, ensuring that air delivery starts and stops efficiently. Additionally, users can adjust the airflow smoothly, supporting safe operation during underwater or emergency scenarios.
Applications
The SCUBA Pressure Cylinder Valve is suitable for:
- Underwater diving cylinders
- Self-contained breathing apparatus (SCBA) sets
- Firefighting breathing equipment
- Emergency response and rescue systems
