--providing 100% visibility are satisfactory for air service to 125 psi to 180°F. Timers have crisp 3-way action, NC or NO, with reset rapid to instantaneous. Our variable chamber provides strict linearity of adjustment and accurate repeatability. Mounted in an elevated position these elements will give many years of trouble free service.
Timers 30 seconds and above have auxiliary port for chamber extension. Timers below 30 seconds may have auxiliary port specified by changing 1st digit to 2.Example: KLC-210 will be a ten second, NC unit with port for extending chamber. Standard chamber volume is 1/2 cu. in.
Shown at right: KLG-121, KLG-102
KLG-121 (brown spool) converts any pneumatic input, slow rising or sharp to a momentary output.
KLG-131 (green spool) blocks signal momentarily.
KLG-102 (green) requires supply  and signal  for output .
KLG-122 (red): supply  no signal = output .
Except for the 30 second and above timers, all units and logic elements are available both in pipe through models, listed above, and bottom ported with 0-ring gaskets in housing. For manifold mounting, change first digit to "0," e.g.,KLG-021 for IMPULSE.
Model MC-902 is a single input binary counter (flip-flop) consisting of two 4-way, 5-port valves plus two NOT elements.
The lower unit or main valve may be used in the circuit as any 4-way, 5-port valve-for example, for operating a double-acting cylinder with supply at center port.
The upper unit has a single input for signal. On rise of signal input the main valve will change state and remain until the signal is recycled.
Where circuit simplification indicates pneumatic counting the MC-902 should be considered. Door opening and closing, automatic positioning and work circuits, sorting or dividing in materials handling, are some examples of applications for this unit.
The binary counter is a fully dynamic system in which speed has been modulated by orifices to achieve compatibility with average input signals. Extremely slow rising signals may require modification by means of a piloted valve or a logic element in order to assure reliability of the counting action.
