Product name:Direct buried type soft sealing gate valve(buried type soft sealing gate valve)
Product model:MZ45X-10/16
Product features
The company produces maintenance-freeDirect buried type soft sealing gate valveIs the Ministry of construction, "construction" eleven five "technical bulletin" the only product promotion application project.
The product can be in the construction of the valve directly buried underground, do not work well, reducing the surface excavation area, save a space position, keeping the pavement in appearance, reduce the difficulty of construction, reduce the project cost, and according to the valve buried depth and the distance between the ground to make any adjustment.Because of the product exposed on the pavement of valve box is very small, so it is suitable for indoor installation underground, can maintain indoor environmental aesthetics.
The product design life of 30 years, long-term use does not leak, maintenance-free advantages, but also can effectively avoid others arbitrarily switch valve and manhole cover and manhole covers theft because of loss of wounding phenomenon.

Installation notes(for details, please refer to the installation instructions)
Gate valve with pipe connection should be natural and smooth, avoid perpendicular to the pipe bending, the gate valve and the valve box, protective pipe section should be kept vertical installation. Should be installed to ensure the telescopic supporting tube and lengthen the operating rod and reliable connection, valve box valve box top location should be level with the ground, requirement of valve extension rod tip to the valve box top distance to 5-10 centimeter advisable.
