Quality and reliability are the most important facts when plant engineers have to choose the components for power stations.

Not matter if nuclear or fossil-fuelled, or when used in plants for renewable energy – shut-off and control valves by POV are first choice when quality and life cycle costing are the selection criteria.







    Different type series ensure that there is always a fitting solution for every application. If it is boiler feed water, condensate, cooling water or coolants – POV offers a reliable valve to fully meet the demands.







      Valves play a critical role in power generation applications, ensuring the efficient and safe operation of various systems involved in the production, distribution, and management of electricity. These essential components come in various types and configurations, each designed to serve specific functions within the complex environment of power plants and electrical grids. By understanding the different types of valves used in power generation 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 power generation 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 and gases, making it ideal for applications where isolation is necessary for maintenance purposes or to prevent contamination, such as in steam and feedwater systems.

      Another popular valve type for power generation applications is the globe valve. Globe valves are designed with a spherical body and an internal baffle, allowing for precise flow control 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 in fuel gas systems, turbine control, and cooling water systems.

      Butterfly valves are widely used in power generation applications due to their compact design and relatively low cost. Designed with a rotating disc that can be turned to control the flow of fluid or gas through the valve, butterfly valves are often used in applications such as air handling units, cooling towers, and condenser water systems, where they help control the circulation of fluids and gases for effective heat exchange and temperature management.







        Check valves play a vital role in power generation 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 boiler feedwater systems, condensate return lines, and cooling water systems, where they help maintain the proper functioning of pumps and other critical components.

        Control valves are essential for regulating various process parameters in power generation applications, such as pressure, temperature, and flow rate. These valves typically feature an actuator and a valve body, which work together to adjust the flow of fluid or gas through the valve according to signals from a control system. Control valves are commonly used in applications such as steam turbine control, boiler combustion control, and heat recovery steam generator (HRSG) systems, where they help optimize system performance and efficiency.

        Safety relief valves play a crucial role in maintaining the safety and efficiency of power generation 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 boilers, pressure vessels, and piping systems.







          In conclusion, a wide range of valves is utilized in power generation applications to efficiently manage the flow of fluids and gases, ensuring optimal performance and safety for both personnel and equipment. From gate valves and globe valves to butterfly valves and check 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 power plants and electrical grids.
