Product Overview of Compressor High-Pressure Safety Valves

Compressor High-Pressure Safety Valves are critical overpressure protection devices in compressor systems, specifically designed to protect compressors  downstream equipment  damage caused by abnormal pressure conditions. When the compressor discharge pressure exceeds the predetermined set value, the valve instantly opens to relieve pressure  automatically recloses when normal pressure is restored, ensuring safe  stable operation of the compression system.

Key Features:

Precise Pressure Control: Accurate spring-loaded design ensures opening pressure deviation ≤±3%, meeting precise pressure protection requirements

High-Frequency Response: Specially optimized for compressor cyclic pressure fluctuations to prevent false actuation while ensuring rapid response

High-Pressure Differential Capability: Designed for compressor outlet high-pressure conditions, suitable for pressure classes up to Class 2500-4500
