Whether during the transport or treatment of municipal or industrial wastewater, or during the production and treatment of drinking water - valves and actuator technology by POV are uncompromisingly made for these applications.

The range covers butterfly and check valves as well as knife gate valves for the use with very dirty fluids. All used materials - from the body over elastomers to the smallest screw - comply with the rules of the DVGW and are accordingly admitted.

Valves play a crucial role in the water and wastewater industry, ensuring the efficient and safe operation of various systems involved in the treatment, distribution, and disposal of water and wastewater. These essential components come in various types and configurations, each designed to serve specific functions within the complex environment of water and wastewater facilities. By understanding the different types of valves used in water and wastewater applications and their unique features, engineers and technicians can optimize system performance, enhance safety, and ensure the proper functioning of critical equipment.

One of the most commonly used valves in water and wastewater applications is the gate valve. Known for its ability to provide a tight shut-off, gate valves utilize a gate that can be raised or lowered to open or close the valve. This design allows for full control over the flow of fluids, making it ideal for applications where isolation is necessary for maintenance purposes or to prevent contamination, such as in water distribution networks and pumping stations.

Another popular valve type for water and wastewater applications is the butterfly valve. Butterfly valves are designed with a rotating disc that can be turned to control the flow of fluid through the valve. These valves are known for their compact design and relatively low cost, making them a popular choice for regulating flow in larger water and wastewater systems. Butterfly valves are often used in applications such as water treatment plants, stormwater management systems, and sewage treatment facilities, where they help control the circulation of fluids and gases for effective process management.

Check valves play a vital role in water and wastewater systems by preventing backflow and ensuring that fluids flow in one direction only. These valves automatically open when fluid flows in the correct direction and close when the flow reverses, protecting equipment from potential damage caused by backflow. Check valves are commonly used in applications such as pumping systems, water distribution networks, and wastewater disposal systems, where they help maintain the proper functioning of pumps and other critical components.

Globe valves are also widely used in water and wastewater applications due to their ability to provide precise flow control. Designed with a spherical body and an internal baffle, globe valves allow for accurate flow regulation by adjusting the position of a movable plug within the valve. These valves are ideal for applications where precise flow rates are essential for maintaining optimal operating conditions and safety, such as chemical dosing systems, pressure reducing stations, and flow control loops.

Ball valves are another common valve type used in water and wastewater applications. Featuring a spherical closure element with a central hole, ball valves can be quickly opened or closed by rotating the ball, allowing for efficient isolation and flow control within the system. Ball valves are commonly used in applications such as water supply systems, chlorine injection systems, and sludge handling systems, where they help manage the flow of fluids and gases.

Safety relief valves play a crucial role in maintaining the safety and efficiency of water and wastewater systems by protecting equipment from overpressure conditions. These valves automatically release excess pressure if the system pressure exceeds a predetermined set point, preventing potential damage to components such as pressure vessels, pipelines, and pumping equipment.

In conclusion, a wide range of valves is utilized in water and wastewater applications to efficiently manage the flow of fluids and gases, ensuring optimal performance and safety for both personnel and equipment. From gate valves and butterfly valves to check valves and globe valves, each valve type serves a specific purpose within the overall system. By selecting the appropriate valves for each application, engineers and technicians can optimize system performance, enhance safety, and maintain the proper functioning of critical equipment in the demanding environment of water and wastewater facilities.
