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.
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 are the common standards for gate valves?
- Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The following common standards for Fujian Biaoguang valve for valve: design specification: JB/T 7746, API602 JB/T 7746, the length of the structure specification / thread socket factory test and inspection of JB/T1751/GB7306, ANSI: B16.11/B2.1: JB/T 9092, API598 pressure temperature: GB/T 9131, ANSI B16.34, MSS GB/T 12220 product ID: SP25 delivery specification: JB/T 7928
- Q:Fire protection gate valve from the wall how many distance there is no regulation?
- Don't know don't answer. "According to the provisions of article 6.2.13 GB50038-2005" code for design of basement for civil air defense engineering, into or through the door unit between the door closed wall should be set up in the inner side or two nominal pressure pipeline is not less than 1.0MPa, the spool is stainless steel or copper gate or globe valve water pipe from the air enclosure structure. The installation position from the wall should be not more than 200mm.
- Q:Function of signal butterfly valve and gate valve
- The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. It can be used as regulating and throttling devices in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. It is widely used in high buildings, fire protection systems and other piping systems that need to display valve switching status.
- Q:What is the difference between cut-off valve and gate valve?
- Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
- Q:Is the axial force and torque of the wedge gate valve the same?
- See where you are, it is better to compare it: wedge type single gate valve features: a structure more flexible, gate valve is simple, sealing performance better than flexible gate valve or double gate valve.
- Q:How to distinguish between gate valve and cut-off valve?
- The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume. 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.
- Q:TitleThe difference between gate valve, butterfly valve and stop valve
- The gate (gate valve) is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle gate valve. The direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
- 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:What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
- Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
- Q:What does gate z41t-10 150 mean?
- According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
