Power

In the power industry, various types of valves are used across different applications to control flow, pressure, and fluid direction in critical processes. 

•Gate Valves: ON/OFF control of fluid flow in pipelines. They provide a tight seal when fully closed and are suitable for high-pressure applications such as boiler feedwater systems and steam lines;

•Globe Valves: Regulate flow by moving a disc against the flow stream. They offer precise control of flow rate and are commonly used in steam control systems, feedwater systems, and cooling water circuits;

•Ball Valves: Use a spherical closure element to control flow. They provide quick shut-off capabilities and are used in various applications across power plants, including isolation and control of water, steam, and gases;

•Check Valves: Allow flow in one direction and prevent reverse flow. They are essential in preventing backflow and maintaining system integrity in boiler feedwater lines, condensate lines, and pump discharge lines;

•Butterfly Valves: Have a disc that rotates 90 degrees to control flow. They are compact, lightweight, and often used in large-diameter pipelines for isolation and throttling applications in cooling water systems and gas flow control;

Pressure Relief Valves: Automatically relieve excess pressure from systems to protect equipment and pipelines from overpressure conditions. They are critical in steam systems, boiler systems, and other high-pressure applications;

•Control Valves: Regulate fluid flow, pressure, and temperature based on signals from control systems. They are used extensively in steam control systems, feedwater systems, and other process control applications in power plants;

•Safety Valves: Automatically open to release excess pressure and prevent equipment damage or catastrophic failures. They are crucial for maintaining safety in steam boilers, pressure vessels, and other high-pressure systems;

•Diaphragm Valves: Use a flexible diaphragm to control flow. They are suitable for handling corrosive fluids and are used in chemical dosing systems, water treatment plants, and cooling water circuits.
