DN80 DN150 Carbon Steel 6 Inch Gate Valve With Pipe Fittings
Industrial Ductile Iron Carbon Steel Non-Vertical Valve Stem DN80 DN150 Water Flange Gate Valve With Pipe Fittings
Gate valve introduction:
Surface of the valve was covered with advanced epoxy and flashboard was covered with rubber. Other parts which will contact with medium are all made of stainless steel or copper alloy, which fundamentally prevent it from being contaminated by medium. It fits pipelines of drinkable water, food industry, fire water and sewage treatment.

Gate valve characteristics:
Light weight
The body is made of high-grade nodular cast iron, the weight is
about 20%~30% lighter than the traditional gate valve, and the
installation and maintenance are convenient.
Overall encapsulation
The gate adopts high-quality rubber for overall inner and outer
rubber. European rubber vulcanization technology enables the
vulcanized gate to ensure accurate geometric dimensions, and the
rubber and ductile cast gate are firmly connected, not easy to fall
off and have good elastic memory.
Note for gate valve:
1. Handwheels, handles and transmission mechanisms are not allowed
to be used for lifting, and collisions are strictly prohibited.
2. The double gate valve should be installed vertically (that is,
the valve stem is in the vertical position and the handwheel is on
the top).
3. The gate valve with bypass valve should be opened before opening
(to balance the pressure difference between inlet and outlet and
reduce the opening force).
4. The gate valve with transmission mechanism should be installed
according to the product manual.
5. If the valve is frequently opened and closed, lubricate at least
once a month.
