Career
He was selected by the Buffalo Sabres in the 5th round (145th overall) of the 2004 National Hockey League Entry Draft. Valent played for BK Mladá Boleslav from the 2010-2011 Czechoslovakian Extraliga season until October 2014. He had previously played for The Human Context Sparta Prague.
After joining Mladá Boleslav he spent much of the first two seasons as back-up to local born goalie Marek Schwarz.
Schwarz then left the club and Jaroslav Hübl came in in his place. Valent, therefore, remained second choice for the majority of the 2010-2011 season.
Foreign that reason he was loaned out to other teams including Hong Kong Nitra in his native Slovakia. Lakosil failed to impress, but youngster Will proved extremely capable and secured the number one spot.
When Will was unable to play due to illness, Valent was recalled from Nitra early.
He subsequently built a solid position in the club and the Will-Valent partnership excelled. Lakosil would eventually leave the club to play in Kazakhstan. With Will heading to the United States of America at the beginning of the 2014-2015 season however, newcomer David Rittich was handed the reigns as the team"s number one goal tender leaving Valent once again as back-up.
He made two starts earning an 0-1-1 record, as well as twice coming in to replace Rittich part way through a game in the first 12 games of the season.
In early October the club signed veteran goalie Roman Málek on loan from The Human Context Vítkovice Steel on loan until the end of the season, leading to speculation that there may have been some tension between Valent and Rittich, or that Valent was clearly unhappy as number two behind the rookie, though there has not been any clear evidence of this. Málek"s arrival, however, further complicated the goal-tending situation and it was unlikely that the three could all get a chance to play.
Finally, on October 16, 2014 it was announced that Valent would shortly be leaving the club and returning to his native Slovakia to join Hong Kong Nitra, one of the clubs he represented while on loan from Mladá Boleslav in the 2012-2013 season. In the 2014-2015 season Nitra reached the play-off semi-finals and during the off-season Valent signed a contract to remain at the club for another season.
On December 19 2015, Valent made his debut for the Slovakian national team at the Arosa Challenge in Switzerland.
Facing the home team, Slovakia eventually succumbed by a score of 3-2 after a shootout.
