Ductile iron valve ,gate valve

Summarize

As the traditional valve products is easy to leak and rust, our enterprise has introduced advanced technology 

and producted resilient sealing gate valve which can overcome the disadvantages including poor sealing 

property, elastic fatigue, easy to rust etc. The resilient gate valve is the updating product, it can reach 

favourable sealing effect by using of the compensation effect of micro-transformation, this valve can be 

widely used in tap water, sewage, construction, food industryelectric power, pharmacymetallurgy, light textile,energy system and so on.


Advantages

 

Flat bottom design

The traditional valve can not be tightly closed if there exists sediment in the valve bottom grooves, our seat 

sealing valve owns the flat bottom design which is the same as water pipe line, so there will be no sediment and 

no leak any more.

 

Overall packaged with glue

The valve adopts high-quality rubber coating with inside and outside of the valve, using the domestic first-class rubber vulcanization technology to ensure the accurate size of the vulcanized valve disc, the solid

 connection of rubber and ductile iron valve disc provide a good elastic memory.

 

Corrosion resistant 

The valve body is coated with epoxy power to prevent corrosion and rusting of the body, and can be used for

 the sewage system.

 

Ductile cast iron material

All the valve body and valve cover are made of ductile cast iron which improve its strength and hardness 

greatly.

 

 

Three O-ring sealing

The three O-ring sealing washer (as the shaft sealing)greatly reduced the resistance and leaking.

 

The precision casting body

The body uses the precision casting which can guarantee the sealing of the valve.

 

Embedded copper nuts

The nuts and resilient valve are combined closely by embedded connection, so the valve may not be loose or

 damaged by vibration caused by water flow.

 

Suitable for drinking

The inside and outside of the valve is electrostatic sprayed with epoxy which can stop the corrosion and rust, so 

the valve can be used in both sewage system and drinking water pipe line.

 

Light weight 

The ductile iron reduce the body weight by 20% to 30%, as itlighter than traditional gate valve, iteasier for

 installation and maintenance.

Q:Pump, valve, these belong to the material?
Pumps, valves are electromechanical equipment, belonging to a class of hardware fittings, but not material!

Q:I would like to ask how to access the valve?
May learn some basic knowledge of valves, learning in practice, relatively fast.
Q:How big valves are used in the DN90 pipeline?
If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding
Q:The valve has a clear opening and closing sign. What does this sentence mean?
Not only on the valve is enough to mark, here means that at the scene can see the installation of the pipe network on the valve open or shut?!
Q:Where is the hydrant main valve?
There is a gate valve at the elbow below the hydrant
Q:What is called protective valve, and other valves what is the difference?
Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.
Q:What are the ten major brands of China's valves?
Tianjin Gangyan guangheng special equipment Limited by Share Ltd is the leader Chinese special material valve industry, a joint venture with Chinese Gangyan established
Q:Who knows what the DE stands for in the valve DE50?
Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.De is the nominal diameter, that is, the outer diameterGenerally speaking, from small to large specifications are as follows de (mm)De20, de25, de32, DE40, de50, de63, de75, de90, de125, de110De160 de200 de250 de315...... Until de800
Q:How to better maintain the valve?
We should keep the valve cleanWe should regularly check and maintain the integrity of the valve the other components. As a fixed hand wheel nut fell off, to be filled and can not manage, otherwise it will grind the valve stem upper garden square, gradually lost with the reliability, and even can not startWe do not rely on the valve support other heavy objects, do not stand in the valveThe stem, especially the threaded part, to regular cleaning, the dust has been soiled should be replaced with a new lubricant, because the dust contains hard debris, easy to wear thread and stem surface, affect the service life
