NATURAL GAS PRESSURE REGULATOR

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.
