What is the valve on the back of a 4041/4040XP closer used for?
Solution ID
56401
Resolution
The valve on the back of a 4041/4040XP closer is a "Back Check Selector Valve" that needs to be turned in on "Parallel Arm" mount applications ONLY.
Notes
If you do not turn the back check selector valve in on the parallel arm applications, back check will come in too late and you do not get the full benefit of the back check feature.
