When it comes to fluid handling systems, valves are the backbone. They regulate flow, control pressure, and keep the system running efficiently. However, not all valves are created equal.

When it comes to preventing backflow, a rubber check valve is the way to go. These valves are designed to allow one-way flow, stopping backflow and preventing contamination of fluids. They are versatile, durable, and easy to install.

Read through the article, where we’ll take a closer look at the advantages and benefits of rubber check valves and why they are a great investment for your fluid handling system.

What does a rubber check valve do?

A check valve also referred to as a one-way valve is an appliance that is installed in a piping system to prevent backflow. It enables the flow of fluids to move only in one direction.  

They are simply passive flow appliances that work without supervision, external energy supply, or manual contribution.

In other words, a rubber check valve is a type of valve that is designed to allow fluids to flow in one direction only. It is commonly used in various industries, including wastewater treatment, food processing, and chemical manufacturing.

How does a rubber check valve works?

The valve consists of a flexible rubber disc that is placed over a port. When fluid flows through the valve in the desired direction, the disc flexes and allows the fluid to pass through. However, if the fluid tries to flow in the opposite direction, the disc closes tightly, preventing any backflow.

This mechanism is what makes the rubber check valve so effective at preventing backflow and protecting sensitive equipment from damage or contamination. The rubber disc is made from high-quality materials that are resistant to chemicals, abrasion, and corrosion, making them ideal for use in harsh environments.

Types of rubber check valve

Rubber check valves are available in a variety of sizes and configurations, making it easy to find the right valve for your specific application. Whether you are looking to prevent backflow in a wastewater treatment plant or protect sensitive equipment in a chemical manufacturing facility, a rubber check valve is an excellent choice.

The different types of rubber check valve are listed below in the FAQ section.  

What to consider when selecting your check valves?

To choose the right check valve for your appliances, the respective selection criteria should be analyzed.

However, there is not one type of check valve that is the finest option for all applicants and the preference may not be equivalently notable for all cases.

Some of the factors that you may need to examine are:-

  •   fluid compatibility
  •   flow characteristics
  •   head loss
  •   non-slam factors
  •   the total cost of ownership.

Benefits Of Rubber Check Valve

While there are plenty of benefits of using a rubber check valve, we’ve listed the most significant ones for you below:

Advantages of using a rubber check valve

Rubber check valves are incredibly versatile and have many advantages over other types of valves.

Low Cracking Pressure

One of the main benefits of using a rubber check valve is that it has a low cracking pressure. TThis means that it opens quickly and easily, even when there is only a small amount of pressure. This makes it ideal for use in applications where you need to control the flow of liquids or gases quickly and effectively.

Easy to Install and Low maintenance

Another advantage of using a rubber check valve is that they are relatively easy to install and maintain. They are also very durable, which means that they can last for a long time without needing to be replaced. This is important, especially in situations where the valve is used frequently.

Chemical Resistant

Rubber check valves are also resistant to a wide range of chemicals, which makes them suitable for use in many different industries. They are commonly used in applications where there is a need to control the flow of aggressive chemicals or gases.

Extremely Versatile

Rubber check valves are incredibly versatile and can be used in a wide range of applications. They are commonly used in the medical, pharmaceutical, automotive, and chemical industries, as well as in many other industries.


Rubber check valves are a popular choice for many industries. They are cost-effective, offering a cheaper solution than other types of valves without sacrificing quality or durability.

Benefits of a rubber check valve over other valves

Rubber check valves are becoming increasingly popular in many applications due to their numerous advantages over other types of valves.

One of the main benefits of a rubber check valve is that it provides a tight seal, preventing the backflow of liquid or gas. This is important in applications where the flow of fluid or gas needs to be controlled.

Additionally, a rubber check valve operates silently, making it ideal for use in areas where noise levels need to be kept to a minimum.

Another advantage of rubber check valves is that they are highly resistant to wear and tear, making them ideal for use in harsh environments where other types of valves may not last as long.

Rubber check valves are also very easy to install and maintain, making them a Overall, the benefits of a rubber check valve make it a highly effective valve option for a wide range of applications.

Frequently Asked Questions:-

What are the most common types of common valves?

The primary kinds of check valves are ball, piston, and stop check valves. Apart from this, there is also a wide variety of rubber valves such as check valves, ball valves, air pressure valves, butterfly valves, etc.

When you should replace the check valves?

Rubber Check valves are normally a low-cost element and as such are often neglected.

Yet, if the rubber check valve shows any indication of crisis or difficulty, the plant operators must strictly rejuvenate the part with a high-quality substitute.

check houses manufactured from rubber may remain completely usable for up to 35 -50 years.

What is the difference between the PSV and PRV?

Pressure Safety Valves (PSV) are generally mentioned as simply Safety Valves.

They are used Adequate pressure from equipment operating Gases. Naturally, the valve extends abruptly in a moment.

Pressure Relief Valves (PRV) in general, are mentioned as simply Relief Valves.

They are used to relieve pressure from equipment operating Liquids. Typically, the valve opens moderately, slowly, and correspondingly.

Wrapping Up!

To conclude, the many advantages of using a rubber check valve make it an ideal choice for anyone who needs an effective and reliable valve for controlling the flow of liquids or gases.

However, selecting the right seller is extremely important so you don’t get any faulty product. We highly recommend you to consider Elasto-Valve Rubber Products Inc (EVR Products) while purchasing rubber check valves.
