The product is the key applied project by"11th five-year developmenttechnical bulletin" from the ministry of construction. It can bedirectly buried underground without building inspection shaft in orderto save excavation space,which keeps pavement beautiful, reducesdifficulty of construction and saves engineering cost as well.
This kind of gate valve can also adjust the distance from the buriedpoint to the ground.the buried soft-sealing gave valve has advantages oflong design service life-30 years,maintenance free,etc.it is also ableto avoid the phenomenon of opening
valve and stealing inspection shaftlid and hurt from missing inspecting shaft lid.
The
gate valve has light switch and novel design,the bonnet ,covered byspecial rubber entirely,achieve the state of no leakage.it adoptedreliable "o"type sealing ring without pressing disk root,and withoutmaintenance.the product adopted Non-toxic epoxy resin electrostaticlayer technology,which will meet the need of drinking water without rustwater.
