Rubber check valve is a device that is used to prevent backflow in piping systems. This type of valve is ideal for many different types of applications. It is able to withstand harsh fluids, and can handle the corrosive environment of wastewater treatment plants.
It is a cost-effective option for controlling back pressure in a system. It also requires very little maintenance. This means that it can be left in place for decades. Another benefit is that it is relatively quiet. However, if the material on the valve seat is worn out, it can lead to leakage. The best way to avoid this is to replace the check valves regularly.
Rubber check valves are available in a wide range of materials. They can be installed in many positions, and are resistant to abrasion. They are particularly useful in submerged conditions. They are also suited for freezing temperatures. They can be made of a variety of rubber compounds, including chloroprene rubber and EPDM rubber. The main advantage of these check valves is their ability to absorb energy. In contrast to metal check valves, which deform and are subject to wear, these elastomers are ANSI/NSF-61 certified. They can handle fluids from -65 F to 400 F.
Rubber duckbill check valves are an efficient solution for controlling back pressure. They are designed to be quiet and require no assistance to operate. They are suitable for use in sewage treatment plants, drainage, breast pumps, and more. They are a cost-effective and energy-efficient way to control the back pressure in a piping system.
A rubber duckbill check valve can be manufactured from food-grade silicone, which makes it an excellent choice for a variety of sanitary processes. In addition to being able to resist mechanical deterioration, it can prevent the rusting of metal swing check valves. These valves are also capable of preventing backflow in the positive direction.
These valves are also available in a variety of sizes. They are typically used in vertical pipe-lines that are oriented upward. They can also be installed on horizontal pipes with duckbill an upward flow. Because the structure of the check valve mimics that of a duckbill, they have a long life span. They are also available in several styles, so you can find one that is perfect for your application.
For example, there are lift check valves that are suitable for high-pressure service. They are a great alternative to hinged cover check valves. They have a specially guided disc that can fit in a dashpot. It is then precisely guided to a seat. Depending on the design of the lift-Check valve, the disc can be shaped into a ball or piston.
In addition to these benefits, rubber check valves are resistant to abrasion. They can also withstand freezing temperatures and ultraviolet radiation. They are also designed for use in tidal operations. They are also resistant to chemicals. In addition to being a very low-maintenance product, they are also easy to install.
