Zenatha Coleman was on target for Valencia but they were held to a 2-2 draw by Micheala Abam's Real Betis at Estadio Antonio Puchades in Sunday's Primera Iberdrola encounter.
The Namibia international last scored what was the winner in her side's 2-0 triumph over Raissa Feudjio's Tenerife last October.
The 26-year-old ended her 10-match drought as she recovered her scoring boots for Irene Ferreras' side, scored in the opening goal but her effort was not enough to see off their stubborn visitors.
Having failed to record a win in last 10 matches, Valencia were desperate to return to winning ways and the Namibian's brilliance gave the hosts a morale-boosting lead four minutes to half-time.
