Check valves come in different types depending on their application. Therefore, you will find that they differ from one another in terms of costs, purpose, efficiency, and fabrication materials.
What are Disco Check Valves
Disco check valves are specially designed valves that only allow the flow of fluids in one direction. They have distinctive features from other types of check valves that make them suitable for their function.
Disco Check ValveBenefits
Reduced Maintenance Costs
Disco check valves have low maintenance costs as opposed to other types of check valves. This is attributed to the fact that they have relatively fewer movable parts.
Minimal Water Hammer Incidents
Disco check valves are poised to be preferable for plumbing applications since they reduce the risks of water hammering.
They are designed to prevent back-flow in fluids/gases by the use of discs in the valves. As, such, they tend to close to allow unidirectional flow of fluids increase of excessive pressure.
They are versatile
They are termed versatile since they are well adapted to operate in both high and low-pressure applications. As such, they have valves that maintain their integrity even in high-pressure circumstances that could otherwise result in water hammer.
Ease of Installation
The installation of disco check valves is poised to be less complicated as compared to other types of valves. Their designs are simple thus making assembling of components and parts to be simple.
Long Life Span
They have a longer lifespan as opposed to other types of check valves since they are made of materials such as such as bronze, stainless steel, carbon alloy, and brass.
Unidirectional Flow
They consist of valves that are designed to prevent back-flow of fluids in pipes. This aspect significantly helps in reducing the risks of water hammering.
Features/Specifications
Disco-check valves have specific features/specifications that aid in their general performance and functionality.
Furthermore, it should be noted that check valve features vary from one type of check valve to another depending on their applications. Below are some of the distinctive features of disco check valves;
- Simple and compact design: This type of check valve has a simple and compact design. As such, this aids in reducing maintenance costs as well as making installation easy.
- Body material: They are normally made of stainless steel material. Stainless steel is known for its features such as resistance to corrosion and rust as well as high tensile strength. This therefore explains the durability of disco check valves.
- Size range: Disco check valves come in different sizes depending on their application. Their size specification therefore ranges from 15mm-150mm.
- Connection type: The type of connection involved in different types of check valves differs depending on installation requirements. For instance, disco check valves exhibit a flanged connection in their installation.
- Pressure range: The pressure range in disco check valves is 150-300 PSI.
Disco Check Valve SpecificationsParts/Components
Disco check valves are made up of different parts that contribute towards controlling the back-flow of fluids in pipes. These parts are listed below;
Seat
It is an important part of the disco check valve since it allows the disc to rest upon it during the closure of the valve. Similarly, it also provides sealing advantages by ensuring a there are no possible leakages.
Spring
The spring is equally important in the disco check valve in that it aids in ensuring a unidirectional flow of fluids. As such, it is designed to stretch or withdraw to control the movement of the valve. For instance, in case of a pressure surge, the string sanctions the valve to close thus preventing the back-flow of fluids.
Body
It forms the outermost part of the disco check valve. It is significant in protecting the internal components of the disco check valve. It is commonly made of materials such as stainless steel but this can change depending on the type and application of the check valve.
Disc
It is usually made of stainless steel material. It is considered the main part of the disco check valve since it primarily controls the opening and closing of the valve.
Spring retainer
It is sometimes referred to as a retainer. It is significantly important in the functioning of a disco check valve since it improves the sealing ability of the disco check valves.
Working Principle
During the closing of the valve, the disc present in the valves is forced against the seat with the help of the spring. As a result, the valves shut to close the pipe system. On the other hand, during the opening of the valve, pressure exerted from the front results in the opening of the valve thus allowing passage of fluids/liquids.
Components of Disco Check ValveApplications
Industrial Plants
Disco check valves are widely used in industrial plants due to their excellent sealing advantages, unidirectional flow of liquids/gas, and simple compact design.
Mining Industry
The mining industry has benefited from the use of disco check valves, especially in the transportation of viscous fluids such as slurry.
Water Systems
Disco check valves can be applied in both residential and commercial water water supply systems.
Oil and Gas Industry
They can similarly be applied in oil and gas plants, especially in their transportation. This is due to their unidirectional flow of fluids/gas.
Heating Applications
Various heating applications have employed the use of disco check valves such as the heating ventilation and conditioning systems.
Conclusion
In summary, disco check valves are crucial in most plumbing applications. Furthermore, they are advantageous over other types of check valves in the sense that they only allow unidirectional flow in fluids/gases.
