A28H-16 spring-loaded full-opening safety valve is suitable for equipment or pipeline of air, steam, water and other media with operating temperature ≤ 200 ℃, as an overpressure protection device.
Structure and Working Principle
- This valve consists of components such as the valve body, valve seat, valve stem, valve disc, and spring.
- When this valve is not in operation or has not reached the specified working pressure, the spring pressure tightly presses the valve disc against the seat to maintain sealing. When the working pressure exceeds the specified working pressure, the valve disc automatically opens to discharge the medium, preventing further pressure increase and ensuring operational safety.
