The Profile Series valves offer a 13 mm lower height profile than other BWT valves. This product line is constructed of the highest quality materials that still keep all working parts above the battery cell. The low profile valve works with high or low pressure, has a hydrometer port and a built-in water level indicator. The new clip-in design makes installation of systems much easier, especially in tight fitting cells.
The Profile Series have the same great internal working features in the design including the patented lever arm that shuts off the water flow to maintain precise electrolyte levels and a water trap to prevent dangerous hydrogen gas movement from cell to cell.
Designed with encapsulated floats, snap-in float guards are completely eliminated! The encapsulated valve protects the float without fear of being accidentally removed.
TB4 = 34-44mm floats
TB5 = 49-59mm floats
