5.The sealing gasket is made of NBR, and thus will not leak, can absorb the impact force.
6.Spring is made of stainless steel, thus has strong corrosive resistance.
7.It can save water yield equipment materials and cost, reduce installation space.
8.As the shape and advanced structure are streamlined, so the pressure drop is small.
9.As the play the role of bypass, so that it hasthe function of recovering the export inside pipe water, and supplement diversion when the import side appears vacuum.
10.Horizontal pipes, vertical pipes can both be installed.
