buried gate valve, gate valves for water

Descripción del producto

The buried gate valve is the key applied project by"*1th five-year development technical bulletin" from the ministry of construction. It can be directly buried underground without building inspection shaft in order to save excavation space,which keeps pavement beautiful, reduces difficulty of construction and saves engineering cost as well.This kind of gate valve can also adjust the distance from the buried point to the ground.the gate valves for water has advantages of long design service life**0 years,maintenance free,etc.it is also able to avoid the phenomenon of opening valve and stealing inspection shaft lid and hurt from missing inspecting shaft lid.The gate valves has light switch and novel design,the bonnet ,covered by special rubber entirely,achieve the state of no leakage.it adopted reliable otype sealing ring without pressing disk root,and without maintenance.the product adopted Non-toxic epoxy resin electrostatic layer technology,which will meet the need of drinking water without rust water.Application: cast gate valve have been widely used all over the China, in many industries_drainage, high-rising building, residential area, sewage treatment, fire control, oil, district heating, electricity etc.Standards: Design standard is according to DIN, ANSI/BS/JIS/EN are also available upon request.Installation precaution (more details are based on installation and operation instruction): water gate valve and pipe connection should keep natural smooth to avoid bending force produced and cage lid and extensible tube should be vertical.meanwhile, to guarantee reliable installation the top of valve box,keeping the same level to ground,would better have ***0 centimeters at the top of extension rod.
