OR gate with two IC 555

how to OR gate two 555, when one 555 cycles at a low frequency a valve turns on an off, the second 555 stretches the ON duration of the pulse with a diode OR gate, this OR output uses sample and hold to get the stable analog data from a sensor after the actuator has gone OFF, this ensures correct reading
