Model NW-SO

Description

Model NW-SO is a spring-operated, flow-to-open, direct-action, loading-type pilot regulator. Used in gaseous service only for pressure reducing or backpressure applications. Multiple range springs cover controlled pressure range from 0.5 - 200 psig (0.03 - 13.8 Barg).

Line Sizes

• 1/4" (DN8) 

End Connections

• NPT (all ports)

Features

• FTO internal path for stability
• Good sensitivity
• Bellows-stem seal for “non-sticking”
• Bronze or SST material
• Std. metal seat or composition soft seat

Applications

Applied in atmospheric industrial gases - GN2, GOX, Ar, He, H2 , CO2 - as well as a natural gas and other process gases. Gases can be corrosive, non-corrosive, combustible, non-combustible, toxic, or non-toxic.

Not for liquid or flashing service. May be used in gaseous cryogenic service with proper materials; consult factory.

Applied where inlet pressure varies significantly, off setting inverse sympathetic ratio (ISR) effects.
