Model NW-PL

Description

Model NW-PL is a pressure-loaded, flow-to-open, direct action, loading-type pilot regulator. Used in gaseous service only for pressure reducing or backpressure applications. Pressure-loading design increases sensitivity by eliminating the resultant “droop effect” range spring. May be loaded with process or auxiliary gas. A Type MA6 with 1:1 loading-to-output ratio is standard; an alternate Type MD6 with 1:3 ratio is available for higher outlet pressures with lower auxiliary loading pressures, and a high sensitivity Type MA7 with 1:1 ratio is available for close accuracy of setpoint at lower outlet pressures.

Line Sizes

• 1/4" (DN8) 

End Connections

• NPT (all ports)

Features

• FTO internal path for stability
• 1:1 or 1:3 ratio loading
• Pressure-loaded for high 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.
