PR3G Series

• Bottom entry cage trim – allows trim to be threaded out for quick inspection and maintenance
• Downstream sensing port – located to reduce droop and increase accuracy and rangeability
• Larger diaphragm area – for improved sensitivity and reduced droop or proportional band
• Versatile application – in sizes from 1/2″ through 2″ (DN15 through DN50) with ranges available for reduced pressure setpoints from 5 psi to 200 psi (0,34 to 13,8 bar)
• High capacities – optimized orifice and body passage sizing leads to high flow capacities
