The Model 80D is a precision two-stage device that incorporates a force balance design with pilot control. This compact, high quality unit combines the flow capacity of a process regulator with the precision of an instrument regulator.

Features:
  • Force Balance and 2 Stage Pilot Control to Minimize Droop
  • Excellent Frequency Response to Eliminate Output Pressure Excursions
  • Compact Size for Installation where Space is Limited
  • Sapphire Orifice Provides Precise Control of Pilot Control Air Flow
  • Low Air Consumption for Efficient Operation
  • Available in 1/8", 1/4" and 3/8"  NPT Port Sizes
The above description encapsulates the entire product series. Specifications for individual configurations may vary depending on the selection chosen.
