The WUV type water supply direct buried (telescopic rod) elastic seat sealing gate valve group adopts a design scheme that can be maintenance free and extend the valve stem. It is buried in one go, avoiding the expensive cost of the valve well and the huge investment caused by multiple road renovations and valve replacements. It beautifies the road environment, is resistant to rolling, and avoids stable accidents caused by the loss of the well cover. The valve stem can be flexibly customized according to the valve well. The top of the valve stem is equipped with a valve switch display, and a signal remote transmission device and a valve misoperation locking device can be installed.

The WUV type water supply direct buried (telescopic rod) elastic seat sealing gate valve group can directly bury the valve underground during construction, without the need to build manholes, reducing the excavation area of the road surface. The well chamber can maintain a beautiful road surface, reduce construction difficulty, and lower project costs. This product is designed to have a service life of 30 years, with the advantages of long-term use without leakage, maintenance free, etc. It can also prevent others from arbitrarily opening and closing valves and stealing manhole covers.

WUV type water supply direct buried (telescopic rod) elastic seat sealing gate valve group inside and outside:

1. The inside and outside of the valve body (including the gearbox) should be shot blasted, sandblasted, and rust removed first, and electrostatic spraying of powdered epoxy resin should be carried out with a thickness of at least 0.3mm. When it is difficult to electrostatically spray epoxy resin on valves, similar epoxy paint should also be brushed or sprayed.

2. The requirements for the interior of the valve body and various parts of the valve plate are that, on the one hand, immersion in water will not corrode, and there will be no electrochemical corrosion between the two metals; Smooth surface on both sides reduces water resistance.

3. The hygiene requirements for epoxy resin or paint inside the valve body should be accompanied by corresponding inspection reports from the relevant authorities. The chemical and physical properties should also meet relevant requirements.
