Model 81 Multi-Stage Pressure Regulator
Features
• Outstanding sensitivity
• Droop or boost virtually eliminated
• Fast response
• Minimal effect for supply pressure
change
• High forward flow capacity
• High exhaust capacity
• Small physical size, saves space
• Sapphire orifice
• Permits use in instrumentation and control
applications
• Provides constant output pressure over
large flow range

Operating Principles
This Model 81 is a precision two-stage
regulator that combines a pilot control
system with a basic force balance system to provide accurate output pressure
regulation.
It is recommended for use in both highly
sensitive instrumentation and control circuits and in equipment requiring high
flow with precise control.
