What Is a Wafer Check Valve?
A wafer check valve is generally a check valve that is used to prevent the back flow of fluids in the pipe line. Due to its small size, it is suitable for installation at the flanges where space could be a limiting factor. In comparison to other leavers designs such as the swing check valves, the wafer check valves are slender and more effective for purposes of industrial use.
Key Features of Wafer Check Valves
The provided specifications of the wafer check valves are as following:
- Compact Design: Saves space and reduces weight in pipeline systems.
- Durable Construction: Built to withstand high-pressure and high-temperature environments.
- Low Pressure Drop: Ensures efficient fluid flow with minimal resistance.
- Cost-Effective: Offers excellent performance at affordable prices.
- Versatile Applications: Suitable for water, oil, gas, and steam pipelines.
Types of Wafer Check Valves Available from China
Currently, RUFSUPPLY manufactures various kinds of wafer check valves which are used in many industries all over the world. Below you will find the most typical definitions:
1. Double Door Wafer Check Valve
Comes with two semi-circular halves that are sprung apart to allow forward flow and shut immediately to minimize the reverse flow.
Popular in HVAC systems and water treatment plants.
2. Flanged Wafer Check Valve
Having flanges at both the ends in order to provide easy connection with other pipe elements or to have an additional layer of seal.
Commonly used in high-pressure systems.
3. Single Disc Wafer Check Valve
A lightweight and cost-effective option with a single disc mechanism.
Suitable for standard flow applications.
4. Custom Sizes
It comes in 2” 3”, 4”, 6”and the 8” sizes that would fit in the varied pipe sizes.
As for the sizes, normal sizes can be produced, but if you have special project demands, it can also be made in accordance with your request.
Wafer Check Valve Installation: Best Practices
Ensure that your wafer check valve is well fixed to get the best out of it and to ensure it lasts seasons. Here are some guidelines that should be followed to have a positive outcome of the installation:
Stept 1.Inspect the Pipeline
It is mandatory that the pipelines are to be free from any dirt, sand or any other unwanted stuffs.
Step 2.Select the Correct Orientation
Position the valve sync with the flow direction arrow facing in the same direction as the flow.
Step 3.Position the Valve Between Flanges
Choose the correct grades of gaskets that will avoid chances of leakage of the liquid being transported.
Step 4.Tighten Bolts Evenly
Tighten each of the flange bolts with a level of pressure that does not apply unequal pressure on the valve.
Step 5.Test the System
Check the functionality of the valve and whether it is working by opening and closing the valve and also whether the valve is tight enough.

Applications of Wafer Check Valves
The wafer check valves produced in China are applicable in wide areas as follows:
Water Treatment
In filtration and pumping systems, backflow is a phenomenon that places a lot of emphasis on prevention due to the possible effects it poses on the quality of the fluid being conveyed in the system.
Oil and Gas
Contribution to proper flow control of pipelines as well as refinery processes.
HVAC Systems
Functional application of heating and ventilation systems in regulating airflow.
Chemical Processing
Preventing backpressure in corrosive atmospheres to check on the equipment.
Power Plants
Prospects in controlling flow high-temperature steam systems.
A wafer check valve is a type of valve used to stop the back flow in the pipelines; the fluid is expected to flow in one particular direction. These factors make it suitable to be adopted by systems which may have limited space. It is commonly employed in industrial equipment and offers dependable operation particularly in water, oil, as well as the gas, and Hepa atmosphere conditioning equipment.
Double door wafer check valves also have two spring loaded disc which closes rapidly thus minimizing water hammer. Because of their design, they are space saver and can be placed even in the corner or in the kitchen with no problem. They are widely applied in the pipelines where low pressure drop rates and control of the medium are needed.
The flanged wafer check valves provide consistent sealing in order to eliminate leakage between the pipelines. They are easy to install and therefore recommended for high pressure systems. Because their IVR is strong and generally have backflow resistant property, they are suitable for use especially in chemical processing, oil and gas, and water treatment industries.
It may also require cleaning of the valve and examination of the seals so as to identify signs of wear. System alignment during the installation process and further tests would help avoid problems with the equipment’s functioning. These measures enable the increase of service life and efficiency of the waver check valves used in industrial facilities.
These check valves are particularly applicable in water treatment, HVAC, chemical, oil and gas applications. These features include their compact size, low pressure drop, and high reliability of such check valves for avoiding backflow in sensitive processes.
The wafer check valve is small and thin as is actuated between two flanges, while the swing check valve is relatively large and thicker. Another distinguishing criterion of the valves is its type such that; While the wafer valves are designed for high pressure, the swing valves on the other hand are mostly used in low pressure horizontal pipeline.
Yes, the wafer check valves that we offer are well made to operate in high pressure conditions. Some of them are constructed the use of stainless steel which makes them strong and fit to be used in challenging conditions such as power station and oil pipelines.
China has an advantage in producing the manufacturing of the wafer check valve through the efficient manufacturing processes, cheap labor, and excellent standardization of their products. Pricing of these valves can be very competitive and in most cases they allow customized productions, this has made the Chinese manufacturers very popular in the global markets.
In HVAC system application, wafer check valve is responsible to control the airflow aptly and also to avoid back pressure. Due to their thin profiles, they fit narrow applications and due to low pressure drop they are very energy efficient thus an important element in heating and ventilation.
The several types of check valves include incomes of stainless steel, ductile iron, and bronze. These materials promote the durability and resistance to corrosion of the valves to match the chemical and water systems industries among others.
