The piston is held in place by attraction to an adjusting screw magnet. A pressure differential is created by flow across the piston. When the differential is great enough, the piston slides to a seat at the outlet port. THe flow rate at which the piston actuates can be changed externally by turning the adjusting screw, thereby changing the piston's relationship with the flow stream.The piston makes a bubble tight seal when it comes in contact with the seat. The reopen the unit, turn the balancing valve handle on the side. This ports the upstream pipeline to the downstream pipeline. When the pressure is equalized on each side of the piston, it will reset. The unit is returned to normal operation by closing the balancing valve.Actuation points for air at 68° F and 14.7 psiaCorrections must be used for other gases, line pressure and temperatures State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
