Gate valves are widely used in industrial boiler and heater process pipelines for reliable on-off service and complete flow isolation. A gate valve operates by lifting a rectangular or round gate/wedge out of the fluid path, providing a full-bore opening when fully open, which minimizes pressure drop across the valve. This makes it ideal for applications where unrestricted flow or tight shut-off is required.
In boiler and heater systems, gate valves are installed in steam, feedwater, fuel, condensate, and flue gas handling pipelines. They are primarily used for isolation rather than throttling service, ensuring safe and efficient operation of the plant. Constructed with durable materials like carbon steel, alloy steel, and stainless steel, gate valves withstand high temperatures, pressures, and corrosive environments typically found in thermal systems.
Gate valves are available in various types such as rising stem, non-rising stem, solid wedge, flexible wedge, and parallel slide designs, depending on the process requirement. Their robust sealing, low flow resistance, and long service life make them a standard choice in boiler and heater applications.
