In principle the FM and the FH and to a degree the NH cabs have a same layout with driver and passenger area, dashboard and seats as the common feature. The lower position of FM cabs is the primary difference between the FM and FH ranges.
What is Valve 21304773?
A Volvo valve is a device for controlling the passage of fluid or air through a pipe, duct, etc, by opening, closing, or partially obstructing various passageways. The simplest valves are one-way-flap mechanisms that allow flow in one direction and shut with back-flow pressure to stop flow in the direction of origin.
The simplest, and very ancient, valve is simply a freely hinged flap that swings down to obstruct fluid (gas or liquid) flow in one direction but is pushed up by the flow itself when the flow is moving in the opposite direction.
Benefits of Volvo Valve 21304773
More accurate control.
Since Volvo valve positioners know the valve's exact position, they provide more precise control than can be achieved by an actuator on its own. In addition, positioners improve accuracy in the lower part of the valve stroke, where errors are more common.
Faster control.
Volvo valve help control valves respond faster to changes in the process variable, minimizing the amount of time the system is operating above or below the setpoint.
Consistent valve position, even with varying pressures.
Varying differential pressure across the valve can indicate instability in the control loop. A positioner is one solution to help stabilize valve position.
More flexible configurations and functions.
A Volvo valve allows you to put distance between the controller and the control valve, as well as to use diaphragm or piston-controlled actuators. You can also switch between direct and reverse control action or change the flow characteristics when necessary.
Gate Valve
It is a valve that opens by moving a gate or barrier out of the way of the fluid. Sometimes this valve is also known as a sluice valve. It works by the disc (single disc or double disc) rotating back and forth in its body. It serves as a shut-off mechanism. Shutoff in double disc valves is good.
Gate valves can usually have rising or non-rising stems. Gate valves come in a range of sizes, from 12 mm to 300 mm and even larger. The gate valves are very co
Globe Valve
It is a type of valve used to control flow in a pipeline that has a generally spherical body with a movable plug or disc element and a stationary ring seat. It also works by a disc or plug rotating back and forth.
The name of this valve refers to the spherical shape of the body. It is divided into two halves by an internal baffle. An opening forms a seat onto which a movable plug can be screwed to close the valve.
Ball Valve
A ball valve regulates the flow of fluid through it using a hollow, perforated, and pivoting ball. A ball valve is open when its hole aligns with the flow inlet, and closed when the handle pivots it 90 degrees, blocking the flow.
In a ball valve, a ball rotates between resilient seats inside a two-way globe. It is small, low maintenance, and needs no lubrication.
It is offered in full, reduced, and venture port patterns. The ball can be rotated a quarter turn to open or close the valve. The ball valve usually provides poor throttling.
Butterfly Valve
The controlling component of a butterfly valve is a disc known as a blade, vane, or flapper. This disc rotates in either a horizontal or vertical direction and permits the flow of fluid. These types of valves can be used for on/off operation or throttling at low-pressure drops.
Check Valve
It is also referred to as a one-way valve or a foot valve. It is a valve that typically only allows liquid or gas to flow in one direction through it.
The use of check valves with pressure relief systems can ensure safety while regulating pressure and gas flow efficiently. These valve types can withstand both high and low-pressure situations. Check valves are available in both vertical and horizontal models.
Power industry
Many power plants generate electric power in steam plants that use fossil-fuel and high-speed turbines. Gate valves are the top choice for power plant on/off applications. Although other valves like the Y-pattern globe valves are sometimes used.
Another type of Volvo valve gaining popularity in this industry, and in fact are making great inroads in a formerly linear-valve-dominated industry, are high-performance critical-service ball valves.
Water works
Water distribution requires relatively low-pressure levels and ambient temperatures. For this reason, different Volvo valve design elements that wouldn't be found somewhere like a power plant, can be used for water works.
As the water temperature is ambient, it allows for the use of rubber seals and elastomers that aren't suitable anywhere else. These types of materials allow water valves to be equipped tightly in order to seal off drips.
Offshore industry
Offshore production facilities and oil rigs have piping systems which contain a plethora of Volvo valves. These are built to a variety of specifications in order to handle all the flow control challenges.
The arterial heart of an oil production facility is the gas or oil recovery piping system. This system isn't always on the platform itself; the production system often operates at depths of 10,000 feet or more.
Wastewater
Wastewater lines collect all the waste solids and fluids and direct them to the sewage treatment plant. Treatment plants feature low pressure piping and valves to carry out their work, and in many cases, the requirements for wastewater Volvo valves are much more lenient than the clean water requirements.
Pipelines
While underground, pipelines are usually made conspicuous by signs, to prevent people digging or, if the pipe's underwater from dropping an anchor in the wrong place.
How are Volvo Valve 21304773 Manufactured?
Valve castings are formed by heating metals to thousands of degrees Fahrenheit, at which point they melt into liquids. The liquid metals are poured into molds, where they cool and take the shape of a specified valve.
Volvo Valve cast blanks are structurally complex, thin-walled shell parts. Valve casting blanks are required to have a smooth surface, a clear character casting, and integral density. In order to meet the above requirements, a series of processing measures should be taken during casting, such as the selection of high refractory molding material and the control of sand moisture, the layering during molding to ensure the hardness of the sand, the use of reasonable casting cap systems and strict control of pouring speed and temperature. Due to its high technical requirements, the casting process of the valve blank is far more complicated than that of general castings.
The finished valves are initially inspected for proper size, position accuracy, and appearance. Then, they are inspected more closely for microstructure, mechanical properties, corrosion resistance, and non-destructive probing. Even the valve inspection, testing process, and quality assurance steps of manufacturing are rather complicated and exhaustive.
The structure and shape of the main parts of the valve are very complex. Some parts are thin-walled and slender, with poor rigidity. When they are machined with industrial tools, positioning and clamping can be very difficult, and complicated special fixtures are often needed.
For some sanitary valve parts, the positioning base has low accuracy and high surface roughness. Sometimes even non-machining surface positioning is used. But there are very high requirements for the accuracy and surface roughness of the processed sealing surface, so it's very hard to ensure the processing quality. Therefore, to meet the processing needs, it is often necessary to increase the accuracy of the positioning base and reduce the surface roughness, or to produce a positioning surface on a non-processing surface, which only increases the complexity of the valve manufacturing process.
Due to the wide variety of valve materials, except for various cast iron and carbon steel, the shearing performance of most high strength, corrosion-resistant, and high-hardness materials is very poor, making it difficult to achieve the specified machining accuracy and surface roughness. And there are very high requirements for the geometrical precision and surface roughness of the sealing surface of the valve, so it's even more difficult to perform mechanical processing on valves. Meanwhile, the poor shearing performance of valve materials causes quite a few new problems for the processing methods, cutting tool materials, excessive shearing, and valve processing equipment.
Parts Of Volvo Valves
Valve Body
The Volvo valve body, sometimes called the shell, is the primary boundary of a pressure valve. He serves as the main element of a valve assembly because it is the framework that holds all the parts together.
The body, the first pressure boundary of a valve, resists fluid pressure loads from connecting piping. It receives inlet and outlet piping through threaded, bolted, or welded joints.
Valve Bonnet
The cover for the opening in the body is the bonnet, and it is the second most important boundary of a pressure valve. Like valve bodies, bonnets are in many designs and models available.
A bonnet acts as a cover on the Volvo valve body, is cast or forged of the same material as the body. It is commonly connected to the body by a threaded, bolted, or welded joint. During the manufacture of the valve, the internal components, such as stem, disk, etc., are put into the body and then the bonnet is attached to hold all parts together inside.
Valve Trim
The removable and replaceable valve internal parts that come in contact with the flow medium are collectively termed as Valve trim. These parts include valve seat(s), disc, glands, spacers, guides, bushings, and internal springs. The valve body, bonnet, packing, et cetera that also come in contact with the flow medium are not considered valve trim.
Disk And Seat
For a Volvo valve having a bonnet, the disk is the third primary principal pressure boundary. The disk provides the capability for permitting and prohibiting fluid flow. With the disk closed, full system pressure is applied across the disk if the outlet side is depressurized.
Valve Stem
The Volvo valve stem provides the necessary movement to the disc, plug or the ball for opening or closing the valve, and is responsible for the proper positioning of the disk. It is connected to the valve handwheel, actuator, or the lever at one end and on the other side to the valve disc. In gate or globe valves, linear motion of the disc is needed to open or close the valve, while in the plug, Ball, and Butterfly valves, the disc is rotated to open or close the valve.
Valve Packing
Most Volvo valves use some form of packing to prevent leakage from the space between the stem and the bonnet.
Packing is commonly a fibrous material (such as flax) or another compound (such as Teflon) that forms a seal between the internal parts of a valve and the outside where the stem extends through the body.
