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 difference between the knife gate valve and the stop valve?
- Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
- Q:Gate valve type Z40Y, Z40H letters - what does that mean?
- According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel
- Q:The difference between flanged gate valve and common gate valve
- General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.
- 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: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.
- Q:How to distinguish between gate valve and cut-off valve?
- Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
- Q:What does gate valve Z44T-10-200 code mean?
- The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu.com/view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200
- Q:What does gate valve DN80-PN16-QT450 mean?
- DN80 means that the nominal diameter of the gate valve is 80mm, and PN16 is the nominal pressure of the gate valve is 16Mpa. Q quick form T cast iron, 450 flanged connection single gate valve.
- Q:What is the difference between gate valve Z41T and Z45T?
- Valve Z41T and Z45T difference is that "41" is dark rod, that is, the screw is not out of the turbine,"45" is the bright rod, that is, the screw out of the turbine.Common points are copper sealed gate valves.
- Q:What kind of gate valve is Z6CS-H102?
- Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
