GATE VALVE FOR power station

Gate Valve for power station handwheel Pneumatic

Specifications

High pressure gate valve, pressure seal bonnet type, when the pressure getting bigger, the tightness will be better.

High pressure gate valve is used for a special system of the power station. It has special requirement in material for the high pressure and temperature service.

Our company has much experience in this kind of valve. Like power station gate valve, globe valve which is suit for high temperature and high pressure conditions in power station system.

Body material: WCB/WC6/WC9/C5/CF8/CF8M/A217 C12A

Operation: handwheel, Gear, Electric, Pneumatic etc.

High pressure gate valve (pressure seal gate valve, valve).

Q:The main question is, what are the functional differences in which case?: 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:Installation and operation instructions of knife gate valve: 3., check the packing parts require compaction, not only to ensure the sealing of the packing, but also to ensure that the gate open flexible;4., before installing the valve, users must check the valve type, size and attention to the media flow direction, to ensure consistency with the valve requirements;

Q:What is the difference between a flanged gate valve and a wire gate valve?: Threaded valve is via the wire or wire is connected with the pipeline, a small general air for the air valve, all belong to this

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

Q:What are the main types of gate valves?: According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;

Q:Gate valve Z41H-16Q generally used for what place?: Gate valve is one of the most commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Suitable for medium and large diameter pipelines.

Q:Soft sealed gate valve and hard sealing gate valve which good?: If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.

Q:What is the standard for ductile iron gate valve set?: The valve material name, specifications and price according to the facts that the valve rod input line.

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:The legend of gate valve and stop valve: When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem. To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below.Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve.The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
