Resilient Gate Valve for Underground

Basic information

Thisunderground butterfly valveis used as a two-way closed circuit device.

Features

1. 2. Does not affect the traffic, and underground parts of the integration, effectively prevent theft;3. Stem has a special extendable structure, which can effectively prevent the ground from sinking;4. Long life, no internal leakage.

Principle

This valve uses the form of pin coupling to transfer the sensor force existing in the gearbox and transmission shaft buried in the ground. The telescopic drive rod is extended until it is installed in the underground bonnet. This layout and approach ensure that work is done properly and efficiently.

Installation and Commissioning

Connect the valve with the water supply pipe, extend the expansion drive rod to the set height, tighten the expansion limit device to maintain the extension height, backfill the pipe groove, tamp and make cement pier foundation, put the valve box plate on the cement foundation, place the valve box cover, lay the road surface and make the valve box cover equal to the road surface. For specific use, please consult ZhengFeng Valve Group.
