Extension Stem Gate Valve

Extension Stem Rubber Seated Gate Valve

Extension stem rubber seated gate valve adopts the maintenance-free & extended stem design scheme.

Once buried to avoid the expensive costs of valve wells and road multiple times reconstructions, meanwhile, this type gate valve do not need replace which avoids the huge investment on this.

The valve stem length can be customized as per the depth of valve wells, there is valve switch display on the top of this gate valve stem, also user can install a signal remote transmission device.

This type gate valve can bury the underground directly during road constructon which reduces the excavation area of road, also the project costs would become less.

Long-term use without leakage and maintenance-free advantages for this type gate valve if compared with other type.

?

Flat Bottom Sealing Design

Traditional gate valves are often deposited in the bottom grooves after washing pipes, such as stones, wood blocks, cement, paper scraps, sundries, etc. It is easy to cause the leakage phenomenon which can not be closed tightly. The bottom of the soft sealing gate valve is designed with the same flat bottom as the water pipe, which is not easy to cause debris deposition and make the fluid unobstructed

Overall Rubber Lined

This gate valve bonnet is lined by EPDM rubber by vulcanized production method which ensure the accurate geometric dimensions, it is firmly connected for rubber and ductile iron material and it will not be esaliy falling off which has good elastic memory of rubber.

Corrosion Resistance

The valve body adopts epoxy spray to prevent any rusty or corrorsion on it, additionally, it is can be used for sewage systems. ?

Not Easily Broken

Traditional iron gate valve usually can be broken when hits or collision or overlap, this type soft sealing gate valve has seldom such situation as its body material changes to be GGG50

Use for drink water system

It is coated with non-toxic epoxy resin for this gate valve inside body ,the inner and outer surface of it are completely covered with rubber which can prevent any rusty ?water or corrosion.

MF Valve Co. got WRAS Certificate of this gate valve which can be using for drinking water system.

1. Lubricate at least once a month if this gate valve is frequently switched.
2. It shall be vertical position between the gate valve, well chamber and well pipe
3. This type gate valve is resistant to rolling which plays an important role in urban construction.
4. Not allowed for lifting for handwheel and transmission gear, and collision is strictly prohibited.
5. The telescopic pipe is correctly connected with telescopic stem when installation, it shall be 8-10cm distance from the top of gate valve telescopic stem to the top of well chamber.
6. Extension stem gate valve designs resonable, it needs once buried only which shall no need making maintenance which save costs for user.
