2. Oil and Gas Industry These valves are used in pipelines to manage the flow of crude oil and natural gas, providing the necessary control to ensure operational safety and efficiency.

Conclusion

Like all mechanical components, DN250 gate valves require regular maintenance to ensure proper functioning. Routine inspections should be performed to check for leaks, corrosion, or mechanical wear. Lubrication of moving parts is necessary to maintain smooth operation, particularly for the handwheel or actuator. Users should also ensure that the valve operates through its full range to prevent seizing.

- Environmental Impact Proper water management through yard gullies can lead to lower risk of localized flooding, which in turn helps in preserving local ecosystems and promoting groundwater recharge.

While gate valves with handwheels offer numerous benefits, they are not without limitations. For instance, they are generally not ideal for throttling purposes, as they are designed for either full open or full closed positions. Attempting to use them for flow regulation can lead to erosion of the gate or seat over time. Therefore, understanding the specific requirements of your application is essential when selecting the appropriate valve type.
