AYT Series Pneumatic Control Valve
Product Advantages
The AYT series locking valve is a pneumatic locking valve that balances safety and high efficiency. It provides intrinsic safety and fail-safe protection, automatically locking in emergencies such as power outages or air supply failures to prevent accidental movement of the cylinder and load. The AYT series employs a high-sealing one-way valve structure, ensuring a secure and precise lock, effectively preventing load slippage or position drift. This pneumatic safety valve consumes energy only during operation, significantly reducing operating costs and achieving high energy efficiency. Its fast response time ensures timely system response, while its internal low-leakage design ensures long-term stability and reliability in the locked state. The AYT series is compact and easy to install, easily integrating into cylinder ports or valve islands, saving valuable space and simplifying the air circuit. The AYT series locking valve is the ideal choice for your pneumatic braking valve, offering peace of mind with its powerful load holding capability and cylinder lowering solution.
Technical Parameters
| Model Number | AYT-400 |
| Action Type | Single Action |
| Signal Pressure | 10MpaNote 1 |
| Set Pressure Range | 0.14~0.7Mpa |
| Air Circuit Cut-off Pressure | MAX0.7Mpa |
| Pressure Differential | 0.01MpaNote 2 |

| Note 1: Ensure a pressure difference of at least 0.1 MPa between the signal pressure and the set pressure. A smaller pressure difference will affect product performance. Note 2: Pressure difference during locking and unlocking. In the event of an accident in the pneumatic operation control circuit due to a fault in the air source or air supply line, locking the valve will maintain pressure at the tool end until the air source or air supply line returns to normal. |

FAQ
-
Q: What is the main function of the AYT locking valve?
A: Its core function is safe holding and precise positioning. In emergencies such as power outages, gas outages, or hose ruptures, it can instantly and automatically lock the cylinder's position, preventing the load from accidentally falling or moving, thereby protecting the safety of personnel, equipment, and workpieces. It is particularly suitable for vertically installed cylinders or applications requiring long-term position holding.
-
Q: What are the practical benefits of its "high sealing" and "low leakage" design?
A: This means longer pressure holding time and higher positioning reliability. In the locked state, it minimizes internal compressed air leakage, ensuring that the cylinder position does not gradually drift or sink due to slow gas leakage, thus guaranteeing production accuracy and stability.
