How To Choose The Right Check Valve

Choosing the right type of check valves in Dubai will require you to consider several factors. From application to configuration, you must look at all factors to choose the best check valve for yourself. Below, we have listed all the important factors to help make your selection process a little easier. Read on to know more 

Types of Check Valves

The first thing you need to consider is the type of valve fit for your application. There are several different types of valves that you can choose from including 

Ball Check Valves

These valves are simple and cost-effective. You will harvest a range of benefits from this valve. Their compact size and no external parts are some of the highlighted features of ball check valves in Dubai. The design and build make them a reliable and affordable solution in the market. However, since these valves do not have an open or close indicator, it can be a disadvantage for some people.

Swing Check Valves

Swing check valves are the most common ones in the market. These are cost-effective and automatic. Thus, these types of valves will not require any external control or power to operate. The operation of this valve is determined by the flow direction. Swing check valves in Dubai come with closed bushings and they do not have an indicator determining the open or close end of the valves. These are mounted using a lever, and the lever enables visual check. 

Tilting Disc Check Valves

The tilting disc check valves in Dubai are primarily used for both water and treated effluent applications. These valves use the 45-degree design to ensure non-impact performance and minimize disc stroke. Since these valves have internal shafts that are within the flow stream, these are perfect for a range of operations. When this valve works with a proper rubber lining, the swing flex check valve will provide a high-wear and corrosive application.

Tilting Disc and Slanted Seat Check Valves

These types of valves will enhance the resistance to water hammers. You will get a double eccentric shaft position and increased seating angle with this type. This means, you will get a slightly shorter valve stroke, and the time taken for the door to close will be reduced. The slanted check valves in Dubai can be installed with an optional hydraulic damper that is located at the internal base of the valve body. The slanted seat design allows these valves to be sealed at lower back pressure which is a major benefit of using these types of valves.

Things To Consider When Choosing A Check Valves

When buying check valves in Dubai, you should consider some important elements. Some of these elements include — fluid compatibility, flow characteristics, head loss, non-slam characteristics, and the cost of ownership. To ensure optimal performance of the valves, you must consider all of these characteristics while thinking about operations and installation. It will give you a better insight into the unit and increase your chances of choosing the right one for your industry.

Fluid

All of the check valves are designed to handle water and treated wastewater. However, when these valves have to handle raw water or sewage water, you may experience some hurdles. Thus, when you are in the process of selecting an ideal valve for your operations, you should consider how the presence of solid material will affect the functioning of your valve. By being aware of this factor in the beginning, you will choose the correct one depending on the type of fluid you want to treat.

Flow Characteristics

When the check valves close rapidly, they will be able to prevent slamming. However, in other cases, the rapid closure of the valve will not be able to prevent ageism. When the pump starts and shuts down, it creates a surge in the flow, and the correct valve will be able to handle it seamlessly. Thus, if you are not comfortable with surges, then choosing a valve with rapid closure is not recommended.

Head Loss

Head Loss is affected by the flow conditions of the systems and the internal surface of the valve. The closure design and build of the valve determine the flow area and thereby affect the head loss. The total head loss includes both static head and friction head. The valve ratings are based on the heat loss. So, if the amount of flow and pressure is a sensitive aspect of your industry, you must consider the head loss rating when buying check valves in Dubai.

Cost of Ownership

The cost of a valve is so much more than the purchase price. While some valves will comprise the purchasing and installation cost, you might need to consider maintenance costs in other cases. When selecting the perfect valve for your industry, it is crucial that you not only consider the purchase price but other costs as well. Some other expenses that must be considered include — installation cost, maintenance cost, energy consumption costs, etc. If the maintenance and energy consumption costs are relatively lower, then it will be a better option in the long run.

Non-slam Characteristics

Slamming is an important characteristic of several industries. While some industries have no problem with slamming, others might want to avoid slamming altogether. The design and geometry of the valve will determine how much reverse flow will occur. The faster the reverse flow, the faster the valve will close, leading to less slamming. You may be able to fix this issue during installation, but it is crucial to consider it before buying check valves in Dubai.

Final Words

Check valves are a vital part of several industries, and buying one is a significant investment for any business owner. Considering all factors will help you assess your needs and match them with the best valve in the industry. These factors will serve as a checklist for you and guide you in the right direction.
