Resilient Seated Gate Valves
The product is the key applied project by"11th 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 buried soft-sealing gave valve has advantages of long design service life-30 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 valve has light switch and novel design,the bonnet ,covered by special rubber entirely,achieve the state of no leakage.it adopted reliable “o”type 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:
Our products 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):
Gate valves 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 5-10 centimeters at the top of extension rod.
