Ductile iron valve ,gate valve


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.



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 




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:Who knows which kind of water valve is good?
Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.
Q:How can I install the water pipe valve?
1. Prepare the glue and saw blade. Disengaging bracket.2, using a hand saw from the valve mouth (spool near) transverse incision.3, the center will be on the move, the longitudinal incision, be careful not to damage the inner tube.4. Clean the pipe mouth, pipe and new valve coating, install the valve.Turn left and turn right |
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:How does the valve open?
Turn the valve counterclockwise, turn clockwise, or turn left, right and leftYou turn the valve to the left.
Q:How can the material be checked by valve approach? What experiments do you need?
First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.
Q:Valve legend
F means the initial letter of the valve, which is shown as a stop valve
Q:How does the valve rust die?
Go to the hardware store to buy derusting lubricant, W40 is fine.
Q:What does the ZH41 valve ZH41 mean, and what other specifications?
Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel
Q:What does LBC mean in a valve?
LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Material is the same, the fuse will not cause shrinkage when you can use
