Body And Bonnet Connection Of Cast Steel Flanged Gate Valves

 

The body and bonnet of Class 150-Class 800 globe valves are usually with studs and nuts,And the body and bonnet of Class 1500-Class 2000 globe valves are usually of pressurized seal design.

 

Back Seating Design Of Cast Steel Flanged Gate Valves:

 

All our globe valves have the back seating design. In most cases, the carbon steel globe valves is fitted with a renewable back seat. For stainless steel globe valve, the back seat is machined directly in the bonnet or is machined after welding. When the globe valve is at fully open position, the sealing of the back seat can be very reliable. However, as per the requirement of API 600, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing

Design Feature Of Cast Steel Flanged Gate Valves

 

Rational structure, reliable sealing, excellent performance, pretty appearance.

Co-radix alloy welded sealing surface, anti-wearing, erosion-proof abrasion-proof and longer use life.

The surface and the adjusting media of the valve shaft are nitrogenzed so that it is erosion and abrasion resistant.

Class1500,the middle 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.

There is no backward sealing structure in the valve, so the sealing is reliable.

The material of the filling and the flange size can be chosen and matched according to the applications and the requirements of the wier/s. That can satisfies all kinds of working requirements

 

 

 

Packaging & Delivery Of Cast Steel Flanged Gate Valves

 

Molded flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish(Ra 3.2µm). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and compactness (Ra 0.8µm) and ensure the reliable tightness of the stem area.

Q:Why the valve can only be fully open and fully closed valve can adjust the flow?
You said the cut-off valve is that the spool is rotating rather than vertical movement structure?Theoretically, the flow regulation can be realized by controlling the position (angle or distance), and all of them have mature products.
Q:Pump adapter generally includes what accessories?
There is integration now.Pump adapter SQ100. All contain.
Q:What are the differences between the gate valve and the cut-off valve?
3, 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 a variety of occasions, such as the valve rod the dark bar valve, 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 and other occasions.4, the cut-off valve is able to stop and adjust the 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 sealing valve has the characteristics of one-way sealing effect, so that the utility model can prevent the working substance from flowing upstream
Q:The difference and use of gate valve and 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's the meaning of the gate valve model z41x 16Q?
Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)
Q:Can the soft seal gate valve reach 25 kg?
Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
Q:What does P54100V mean in power station gate valve Z960Y-P54100V?!
P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar
Q:Analysis of the advantages of elastic seat sealing gate valve?
General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.

Q:Does the tap belong to a stop valve or a gate valve?
Most taps are stop valves:1, gate valve (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.2, valve (stop, Globe, Valve) of the opening and closing parts are plug shaped valve, sealing surface is flat or sea cone, the valve along the center line of the valve seat in a straight line movement. Stem form of exercise (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Therefore, this type of shut-off valve is very suitable for cutting or regulating and throttling. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation.The stop valve is an ascending stem type, and the handwheel rotates and rises along with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!
