The key to superior bi-directional sealing is the “sure-seal” system. This unique “thru conduit” design provides both upstream and downstream sealing, creating a pressure energized balance between the gate and seat assemblies. The “sure-seal” seats expand against the floating gate when subjected to line pressure to form a positive metal –to – metal seal.

Gate valves have a thick solid gate attached to the valve stem with a “T” nut that allows the gate to “float”, reducing deflection and binding at extremely high line pressure. Gate Valves will not pressure lock and require minimal torque to open and close the valve.

The body cavity is exposed to line pressure only during valve opening and closing, ensuring better lubricant retention, less exposure to line contaminants and longer service life with less maintenance.
