Career
Valvekens was professed as a Franciscan friar in 1628, celebrating his jubilee of fifty years on 12 June 1678. On the basis of papers left by Jean Verdonck at his death in 1672, Valvekens edited a history of the foundation of the Franciscan house in Diest, Ortus, progressus et modernus status conventus Fratrum Minorum Diestensis. This manuscript survived the suppression of the house, and was a source for F. J. East. Raymaekers"s ecclesiastical history of the town, Het kerkelijk en liefdadig Diest (1870).
He died at the age of 78, having been a Franciscan for 53 years.
