This valve is of a right-angle structure. The flow direction is unidirectional. Please ensure that the arrow on the valve body is consistent with the direction of the medium flow. 
4. Installation location It should be installed at a position that is easy for maintenance. Moreover, a stop valve must not be installed in front of the valve to avoid affecting the pressure relief function.

Notes for Attention
1. Prohibit unauthorized disassembly or adjustment of the spring: The pressure of this product has been fixed during manufacturing. Unauthorized adjustment may lead to uncontrolled pressure, resulting in safety hazards. 
2. Prohibited for use in systems beyond the pressure range: Please select the appropriate specification of the safety valve based on the working pressure of the system. 
3. Regular Testing: For systems that have not been used for a long time, a manual test must be conducted before use to ensure that the valves are functioning properly. 
4. Keeping children away: The installation location should be designed to prevent children from accessing it, to avoid burns or accidental operations.
