JCS - Model 420-C -Cylinder Mounted Regulator
The JCS Industries Model 420-Cylinder Mounted Regulator is designed for years of safe and reliable service. Incorporated into the robust design and machined front and back bodies, internal (Non-latching) switching mechanism, internal pressure relief vent and a non-metallic inlet valve assembly. The Model 420-C Vacuum Regulator can be either direct ton cylinder mounted or installed on multiple cylinder pressure headers. The JCS Model 420-C operates as a pressure reducing valve to transfer gas under pressure to gas under vacuum within the chemical feed system.
Installed between the cylinder/container of the chosen gas and the Chemical Feeder Model 4200, the Model 420 will switch from one cylinder/container to the next one in line as soon as the gas in the first cylinder is depleted. An internal switchover valve is automatically initialized in the event of gas supply failure; the reduction of the vacuum will isolate the regulator diaphragm cavity from pressurized pipe work.
