Hi Pattabi,

Try with:

from quantum.api.v2 import attributes

def _validate_range_or_none(data, valid_values=None):
      if data:
           _validate_range(data, valid_values)

.....
'delay': {
    .....
    'default': attributes.ATTRIBUTE_NOT_SPECIFIED
    'validate': {'type:range_or_none': [1, 120]}
    .....
}
......

validators = {
     ....
     'type:range_or_none': _validate_range_or_none
     ....
}


Regards,
Salvatore
