There are several types of Check Valves. We’ll look at Ball, Poppet, Wafer, and Spring-loaded Check Valves. Choosing the right type depends on the application, but there are several important factors to consider when selecting a manufacturer. Listed below are some of the major types of Check Valves and their advantages. If you’re not sure what you need, contact a manufacturer today to learn more. They can provide expert advice and supply the right check valve for your specific needs.
Ball check valves
Ball check valves are available in a variety of materials, ranging from thermoplastic to fiberglass. Low-pressure versions are ideal for use in applications such as water, mining, fertilizers, oil, and irrigation. Depending on the material, the valve can operate at pressures ranging from 725 to 15,000 psi. These valves can also be used for transportation and water treatment. Some industries that can benefit from these valves include the chemical, oil, and pharmaceutical industries.
Poppet check valves
The basic concept of a poppet check valve is that the disc that serves as the checking mechanism is located at the end of the sleeve or stem. In order to prevent hydraulic shock and other dangers associated with backflow in high-pressure situations, the disc is normally spring-loaded. The resulting valve is a reliable and durable option for high-pressure applications. There are many different spring cracking pressures and seat materials available from manufacturers.
Wafer check valves
One of the most popular types of check valves is the wafer check valve. Their slim design and simplicity of operation make them popular for many different applications. Some of these applications include desalination, wastewater treatment, aquariums, and chemical processing. Wafer check valves are also used in the chemical process industry to regulate flow and dosing of industrial acids. These valves are commonly used in chemical processing plants, mining, and other industries that deal with fluids.
Spring-loaded check valves
Spring-loaded check valves are commonly used in water treatment plants, freshwater supply systems, and chemical manufacturing facilities. In addition to their widespread use, they’re also used in the food and pharmaceutical industries, heating ventilation air-conditioning systems, and oil and gas processing. Their advantages include a low pressure drop and immediate closing, which makes them ideal for applications where a quick reaction time is important. They can be installed in many different configurations.
Press-in check valves
The construction materials of check valves play an important role in their performance. If the materials are incompatible, the valve could fail to seal properly and may lead to contamination of the flow of process fluids. The common materials used for check valves are brass, ductile iron, copper, polyethylene, polypropylene, aluminum, steel, and rubber. If you are looking for a high-quality valve, consider working with a reputable manufacturer that has a proven track record of success.
