FIGURE 2-1 Installation Dimensions

“C” Dimension for strokes 19" or longer, with 3-15 psi

instrument pressure range = 0.68 x stroke.

Example: 19" stroke, C = 0.68 x 19 = 12.92"

Notes:

1) All connections 1/4 NPT with exception of 1/8 NPT

gauge connections.

2) Increase in instrument air causes increase in pressure

at “Valve 2” connection. “Valve 2" pressure must be

applied to actuator so as to extend range spring and

restore balance.
