Los Che were comfortably ahead following Aly Cissokho's header off a free-kick early on in the first half. But the Frenchman was dismissed for bringing down Omar Ramos inside the penalty box when the latter was on the verge of firing a shot from close range.
Pellegrino feels that the referee got the decision wrong as television replays seemed to indicate that there was little deliberate contact on the part of the Valencia defender.
Victor Perez netted the subsequent penalty to level the scores and both sides failed to find a winner in the remaining 25 minutes.
Roberto Soldado was brought into the game to replace Nelson Haedo Valdez in the second half following an injury to the Paraguayan. The Valencia captain managed to get a late chance from close range but could not score the decisive goal.
The result means that Valencia, last season's third-placed side, continue to lose ground to teams near the summit and are currently in ninth place, four points away from fourth-placed Real Betis.
"We are not happy with the result because we wanted to win," Pellegrino told reporters after the game.
"It was not a penalty, Omar hit the ground when he saw that Valencia were going to regain the ball.
"The match totally changed with Cissokho's red card, but for the final eight minutes we still regained control of it.
"Overall the game was even and they had not had many chances.We were organised, but lacked the freshness to subdue Valladolid."
Predictably, Valladolid coach Miroslav Dukic felt that the decision that turned the game was a correct one.
“The penalty seemed clear to me, while both Omar and Alberto Bueno did well moving between the lines," he commented.
Valencia next play relegation candidates Espanyol on Saturday.
