Rubber check valves are a type of back flow preventer that are used to control back pressure in a piping system. These valves have several advantages over metal check valves and are designed to last. They can be used for a variety of applications and are ideal for submerged or underwater conditions. They are also quieter than metal check valves.
They are a simple, inexpensive solution for controlling back pressure. They are resistant to freezing, corrosion, and daily operational vulnerabilities. They are able to handle a wide range of fluids and are available in many different variations. They are also available in various sizes, making them easy to install and maintain.
They are made from EPDM and chloroprene rubber. These valves are ANSI/NSF-61 certified. These valves are able to withstand a wide range of temperatures and are suitable for ultraviolet radiation. The elastomers are capable of handling fluids ranging from -65 F to 400 F. They also provide superior protection from abrasion and sludge.
Compared to metal check valves, they are able to withstand harsh conditions and resist wear. They are able to be installed vertically or horizontally and will not deteriorate over time. They do not require a water hammer or other outside power to operate. They are also able to handle large obstructions.
They are able to work quickly, and will continue to function despite exposure to sludge and sediment. The elastomer will withstand wear and tear, and the valve will not deform. They are also able to absorb energy better than metal check valves. This makes them a good choice for systems that need to be resilient.
These check valves are easy to install. The valves come with a heavy-duty stainless steel clamp that affixes to the pipe. The clamp is reinforced with a nitrile jacket. They are drilled to 150# standards and flanged to fit inside existing pipes. They can also be bolted directly to new installations. They are a cost-effective option for tidal operations and other applications.
The Zoeller 30-0181 check valve is a popular model that is highly recommended by homeowners. It can handle water up to 10 feet of head height. It is also made from PVC, and it has a bending flapper that rubber check valves can withstand 4.3 PSI. The valve is also able to withstand temperatures of up to 130 degrees Fahrenheit. It is an efficient and economical way to control back pressure in a piping systems.
Flexicraft Rubber Duckbill check valves are also a reliable and economical choice to control back pressure. These valves can be operated without assistance and are designed to replace flap type check valves. They can be fitted with an optional stainless steel or brass sleeve for increased durability. They are ideal for both tidal and sewage operations. They are also able to handle mineral based oils, lubricated oils, and synthetics. They are also able to handle hydraulic fluids that can reach 6,000 PSI.
