Shutter body, shaped drawer plan, Gate or glasses, is preavazut sealing systems on the two sides, so that valves of this type may be used for flow in both directions. Sealing element is made from rubber, brass or bronze, as are valves are low, medium or high pressure. Submersible send with gate valves to plan or by opening shutter body, in the lower close produces a discontinuity in current management, the likelihood of formation of vortexes. Hydraulic losses due to these phenomena by these kinds of valves are important. To avoid this inconvenience of such a model submersible pumps, valves using glasses, shutter whose body is extended in the bottoom with a ring.Pumping tank valvePumping tank valvePumping tank valve
