Q: What do you mean by "2" and "200 CF8M"?: CF8M is stainless steel, and 2 is caliber 50200 and should also be bore

Q: what are their applicable conditions? Advantages and disadvantages?: Valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material for different media. In various types of valves, gate valve is the most widely used.Advantages: low fluid resistanceSmall torque required for opening and closingYou can use the ring road in which the medium flows in the two direction, that is to say, the medium is free of flowWhen fully open, the sealing surface is less eroded by the working medium than the cut-off valveThe structure is simple and the manufacturing process is betterThe structure length is shortDisadvantages: the overall size and opening height are larger, the space required for installation is also largerIn the process of opening and closing, there is relative friction between the sealing surfaces, and wear more easily, and even cause friction at high temperatureGeneral gate valve has two sealing pairs, to the processing, grinding and maintenance increased the number of difficultiesLong opening and closing time;

Q: Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

Q: What is the standard for ductile iron gate valve set?: Clear shot valve installation, is still under way of connection and specifications set "water supply and drainage, heating, gas engineering" or "industrial engineering" pipeline register quota corresponding specifications and installation methods of connecting the valve installed valve section.

Q: Does the relief valve have a gate valve?: With the ball valve, needle valve, with the valve did not see, but there should be some.

Q: What are the features and uses of the gate valve?: What is gate valve? What is the purpose of forged steel gate valves? What are the features of forged steel 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 gate valve movement direction perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angles vary with valve parameters. Gate valve drive classification: manual gate valve, pneumatic gate valve, electric gate valve.DefinitionGate valve means the closing of the valve (gate) along the central line of the vertical direction of the valve. The gate valve is mainly used for cutting in the pipeline.The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is betterValve also has shortcomings:The overall size and opening height are larger. Larger space required for installation.In the process of opening and closing, there is relative friction between the sealing surfaces, which may cause galling.Gate valve generally has two sealing surface, processing, grinding and maintenance to increase some difficulties.

Q: What is gate well?: Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.

Q: Generally, how big is the diameter of the installation flange plate gate valve?: Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)

Q: What is the difference between gate valve and gate valve? Is it the same valve?: The same, very few people call gate valve, all call gate valve.

Q: Which is the most expensive, check valve and gate valve?: In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124
