Product Description:

Gate Valve

 Flange ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between class150-2500, working temperature≤600°C, in oil industry, chemical industry, fossil-field power plants.

Design Feature of  Gate Valve

1. Both design and manufacture are carry out strictly fellow API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.

2. Co hard alloy welded sealing surface, which is wearing resistance, erosion proof, abrasion proof and long-lived.

3. The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistance.

4. Class≥900LB, the media cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.

5. There is backward sealing structure in the valve, so the sealing is reliable.

6. The material of the filling and the flange size can be chosen and the matched according to the applications and the requirement of the wier's. That can satisfy all kinds of working requirements.

Q:What's the meaning of the gate valve model z41x 16Q?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = flange connection1 = structural form: wedge type single gateX = sealing surface material: Rubber16== pressure rating: 1.6MPaQ== body material: ductile iron
Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?
Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.
Q:What are the types and product categories of knife gate valves?
Types and classification of knife gate valves:PZ73H, PZ73F, PZ73Y manual knife gate valve: manual drive, clamp connections, rod parallel rigid single gate and valve seat sealing surface is made of hard alloy, Teflon or stainless steel body processing, nominal pressure.2PN10~16, the valve body material for carbon steel (PZ73H-10C/16C), stainless steel (PZ73F-10P/16P PZ73Y-10P/16P), with the function of slag gate valve.
Q:What type of flange does it fit with the gate valve?
According to the welding plate flange, flange material selection of piping material.
Q:Does the tap belong to a stop valve or a gate valve?
If it is about to pull open and close, it is cock valveIf it is rotated up and down, it is a stop valve
Q:What does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
Cast steel flanged gate valve 25 pressure bore 250
Q:Is the check valve in or behind the gate valve?
Check valve in the valve in front. To prevent water from flowing back.
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.
We focuses on supplying special valves applied to long-distance pipelines, petroluem, petrochemical processing devices and other harsh working conditions.We offer integrated solutions for industrial valves.The leading products of group are ball valve series, control valve series, cryogenic valve series, high temp.& pressure valve series, special material and process valves series.
