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
Media Resistance:
Gas compressors: H₂S corrosion resistance
Process compressors: Compatibility with various process media
Air compressors: Anti-fouling design
Stable Relief Performance: Improved disc guidance structure ensures stable, chatter-free pressure relief
