Compressor Valves - Process Gas
“Tolerance Rating”气阀-对工艺气忍 耐度
Compressor Valve Type Magnum (PEEK 子弹头） Poppet 提动头(蘑菇状) Concentric Ring (Plate) 环状 Ported Plate 片状带孔 Channel 槽式
Increased hardness
Excellent chemical resistance to corrosives
Can increase pressure packing service life by up to 2 - 3 times (especially in higher pressure applications)
Advanced valve element geometry
Precision-guided valve elements and springs
Streamlined flow path with balanced seat, guard and lift areas optimize EFA; good tolerance for liquids and particulates in the gas
Registered D-R trademark
Packing case designs:
• Meet (or exceeds) API 618 standards • Available in a variety of materials
including cast iron, alloy steels, and stainless steels

Process Poppet Valve Features -
Why it Works 菌状阀
Poppet element design - rigid & tough
Spring design - lower stresses than plate style valves
Offer at a lower cost than existing ring, plate or poppet style valves

MagnumTM Compressor Valve
子弹头 气阀
Features:
Rigid and tough (low mass) non-metallic sealing element for maximum impact resistance
Compressor Valves 气阀
Ranked #1 as primary cause of unscheduled shutdowns
Some valve types / designs more tolerant than others of actual service conditions
Caution - all poppet style valves are not equal!
