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

Features

• Force balance and pilot control to minimize drift.
• Excellent frequency response to eliminate output pressure excursions.
• Compact size for installation where space is limited.
• Sapphire Orifice provides precise control of air flow through nozzle.
• Low air consumption for efficient operation.
• Available in 1/8”, 1/4” and 3/8” NPT port sizes.
