The model 67 is a visual flag indicator with manual reset and comes standard with an isolation ball valve.
The integral isolation feature of the Model 67 means the cost, time and safety concerns of de-pressurizing and draining a
line are eliminated. Now the pig passage indicator can be isolated, removed, repaired and reinstalled while the pipeline is
flowing and pressurized. Preventative maintenance, inspection or repair are easily accomplished without specialized
equipment or crews.
Includes a thread mounting nipple, isolation extended lower housing with fluorocarbon O-Rings, and hemispherical plunger
with a flag assembly.
