Battery Watering Technologies’ new VB-TBU valve is an encapsulated valve offered for commercial applications. The new valve design was originally intended for the Trojan PLUS Series batteries to prevent the valve from being damaged by the vent opening obstruction during installation. The shut-off level for the VB-TBU is the same as the VB-TBB valve. Due to the performance and robustness of the new VB-TBU, they will replace the VB-TBB valve with the VB-TBU valve effective October 11th, 2016. Kit part numbers will not change. If a replacement valve is needed for the VB-TBB, a VB-TBU will be shipped.
