Johnson Controls C-202-1 2:1 Ratio Cumulator, 1/8 FPT Connection [New]

The C-202 Cumulator is a reverse acting device with a ratio of 2:1. A reverse acting cumulator decreases output pressure with increasing pilot pressure. The C-202 is used singly or in groups to accumulate the effect of two or more controllers operating a device.

Air connections are made with barbed fittings for 5/32 or 1/4 in. poly tubing. These fittings are field supplied for the reverse acting model. The supply, output, and pilot air connections are marked S, O, and P respectively.

The C-202 varies its output pressure in proportion to pilot air changes at a 2:1 ratio; the output changes 2 psi (14 kPa) for each psi change in pilot air pressure. The output of the reverse acting model is adjustable from 20 to 12 psig (140 to 84 kPa) for 0 psig input.. Johnson Controls. Johnson Controls. C-202-1.
