Introducing the A48Y type safety valve, engineered to serve equipment and pipelines containing steam, air, and other media at working temperatures up to ≤350°C. This precision overpressure protection device activates automatically when the pressure surpasses the permissible threshold, discharging the entire excess. Once the pressure normalizes, the valve seals securely, guaranteeing the safe operation of your equipment and pipelines.

Q1:What is a safety valve?
1. Safety valves are essential for protecting lives, properties, and the environment. Designed to release overpressure from containers or devices, these valves reopen upon pressure normalization, preventing further fluid release.
2. As critical safety devices and often the final defense line, safety valves must function reliably under all conditions. These specialized valves are not to be mistaken for process valves or pressure regulators and should be used exclusively for overpressure protection.
Q2:How does a safety valve work?
The operational mechanism of a safety valve includes the following steps:
1. Opening: Upon system pressure exceeding the valve's set limit, the valve disc opens due to medium pressure and spring force, effectively releasing the excess pressure.
2. Maintaining Open: As system pressure stabilizes within the set range, the spring remains balanced, keeping the valve open and the system under controlled stress.
3. Closing: When the system pressure drops below the valve's set level, the spring's inability to lock and seal causes the valve disc to close, preventing any further increase in medium pressure.
