Compressor Valves 气阀
Ranked #1 as primary cause of unscheduled shutdowns
Some valve types / designs more tolerant than others of actual service conditions

Compressor Valves - Process Gas “Tolerance Rating”气阀-对工艺气忍耐度
Compressor Valve Type Ranking
Magnum (PEEK 子弹头) Excellent顶好
Poppet 提动头(蘑菇状) Good 好
Concentric Ring (Plate) 环状 Good好
Ported Plate 片状带孔 Good好
Channel 槽式 Fair一般

Process Poppet Valve Features - Why it Works 菌状阀
Poppet element design - rigid & tough
Spring design - lower stresses than plate style valves
Streamlined gas flow - allows gas contaminants to pass through; reduces plugging
Reconditioning - simple and easy; minimizes rebuilding & assembly errors
Caution - all poppet style valves are not equal!

Compressor Valve Technology: We’ve raised the standard把气阀技术再度提高
Objectives:
To further improve the performance and reliability pressor valves
bine ideal design features of various valve types into a single design
Extend application of a single design to a wider range of speeds and pressures
Offer at a lower cost than existing ring, plate or poppet style valves
5
Features:
Rigid and tough (low mass) non-metallic sealing element for maximum impact resistance
Minimal tensile loading in sealing elements
Minimized fixed clearance
Large (effective) flow area at minimum lift
Available, low cost sealing element eases reconditioning and reduces inventory
Can be used in conjunction with port, plug and finger type unloaders
