Cock Valves in Dubai UAE

The valves are called cock valves and are called plug valves. Stop valves or quadratic valves are also devices that allow the user to provide flow from an external point through a restriction or permission. They can be used as far back as antiquity, and they are one of the simplest tools for controlling fluid flow. For example, when you turn on the tap for something like brushing, open a valve that allows water to escape from the pipe.
The valve is a mechanical device known as one of the products of the Marine Land in Dubai and Sharjah, which partially or completely blocks a pipe to change the amount of fluid that passes through it.

Valves are mechanical/electromechanical components that regulate fluid flow in a variety of ways. They are vital to many industries and make new hydraulic/pneumatic technologies possible thanks to their ease of use and cost-effectiveness.

What are Cock Valves?

Cock valves, also known as plug valves, stop valves, or quadratic valves, are devices that allow the user to restrict or allow flow from an external point through a pipe. They have been used since ancient times and they are one of the simplest tools to control the flow of fluid. The valve is often activated manually with a handle but can also be activated remotely via additional systems. They are useful for preventing fluid/pressure movement from the valve, but can also be used to adjust specific flow. However, these types are less common. The sleek, simple, and realistic design makes them super versatile valves, so cock valves can be found throughout plumbing, heating/cooling, refrigeration, HVAC, and other industries.

How do cock valves work?

Cock valve is easy to use. Simply turn the knob to allow the liquid to pass through the valve. It uses a cone plug-in that has a transit port. By rotating the stem 90 degrees, the fork rotates, causing the passage valve to run parallel or perpendicular to the flow, eventually stopping the flow through the valve. While simple in design, engineers have built-in cock valves to create multi-port valves, flow regulators, and other complex designs. You will see different changes in the next section, but know that they all work according to this basic principle.

Types of cock valves

Like all engineering devices, cock valves are optimized to meet the needs of specific applications. Below is a brief overview of the different types of cock valves and should provide an idea of ​​the variety of these valves. Note that there are more types and this section is an overview of the types of cock valves.

• Non-lubricating valves

Cock valves without lubrication, well, without lubrication. A seal is made between the metal body and the plug, and in the past, the seal was made entirely of metal. In more modern designs, polymer sleeves are inserted between these components to reduce friction or are raised when turning the fork to reduce low valve wear. Lubricated cock valves are very useful for applications that are difficult or impossible to maintain, such as very dangerous chemical applications or reactive fluids.

• Lubricated valves

A lubricated cock valve is no different from other types, except that a viscous lubricant such as oil or grease is placed between the shower plate and the body of the valve. This results in better sealing and further friction reduction but makes these valves inherently more maintenance-free because repeated use requires re-sealing the valve with lubricant. As a result, lubricated valves are suitable for rare operations and in applications where the process fluid has grains/dirt that can contaminate the valve.

• Multi-port valves

Multi-port tap allows for more than 2 connection points, and more options when switching between routes. There are 4-way valves, but valves 3 and 4 are available for specific needs. Plugs often replace wall/door designs, where 1-2 paths are blocked, allowing fluid to flow in only two paths. These multi-port designs are especially useful for reducing the number of valves used in the design and are great for more complex projects that require special switching. As the complexity increases, the risk of failure increases, but designers should be aware that multi-port cock valves may require more maintenance.

Specifications and selection criteria

Because these valves are simple, it may not take long to determine an all-purpose cock valve for your job. Sophisticated applications, on the other hand, require more information before contacting your supplier directly. Take a look at the following specifications and selection criteria for cock valves to see how to choose the right one for your needs.

• Type of valve

Consider your program and determine the type of stimulus and the number of ports required in the valve. This specification reduces the list of potential options because valves that obviously do not match your schedule are removed first. The type of valve is also determined by all the other specifications, so keep a list of different potential options and see which one best suit your needs.

• Nominal pressure and pressure range

Will the valve experience any pressure? If so, determine the range of pressures it will face and make sure the cock valve of choice for those forces is calibrated. If these specifications are ignored, the valves may fail or not work as intended, so make sure this is especially known for high-pressure applications.

• Tube size

The size of the pipe used in the system is a critical specification. Improperly sized valves either do not connect easily or cannot handle the process fluid. As a general rule, the size of the valve should never be half the size of a tube. Also, know that most cock valves on the market are in standard tube sizes and individual sizes are harder or have to be made specifically.

• Material and chemical interactions

Because cock valves block the flow through the pipeline, this process fluid will be in contact with the valve for a long time. Make sure that the right ingredients are selected for the valve so that it does not weaken its integrity for a long time. For example, an acidic solution may destroy the iron valve body over weeks or months, but it will have little effect on stainless steel. Also, choose a material that does not allow it to settle or accumulate, as this can damage your pipes as well as your valves. Determine the chemical contraindications of your process fluid and select the appropriate material to explain these potential problems.

Applications

Cocks are flexible and delicate components that are widely used in most industries. They offer on / off control, throttle, and flow deflection and can be rated for low-pressure and high-pressure applications. It is impossible to name any application of cock valves, but the list below should give you an idea of ​​their most important uses.

Some notable uses of cock valves include:

• Gas and fuel applications
• Water systems (plumbing, sewage, etc.)
• High-temperature flow / boiler feed water
• Low-pressure steam applications
• Corrosive chemical applications
• Oil pipelines
• Power plant applications
