Unique bi-directional sealing design provides a thru-conduit, upstream and downstream seal which creates a pressure-energized balance between the slab gate and seat assemblies when subjected to line pressure.
T-slot stem and gate connection allows the gate to “float” between seats without misalignment of the stem under pressure.
The body cavity is exposed to line pressure only while the valve is being cycled, ensuring better lubricant retention, less exposure to line contaminants and longer service life with less maintenance.
