Tips: What are common issues and failures associated with flanged gate valves?
Common issues and failures associated with flanged gate valves include leakage, which can result from damaged or improperly seated seals, or wear and tear on the valve components. Corrosion is another prevalent problem, particularly in environments with aggressive fluids. Sticking or jamming of the valve gate due to debris or inadequate lubrication may hinder proper operation. Over-tightening of the bolts during installation can lead to distortion of the valve body, affecting its performance. Additionally, the valve stem and actuator may experience wear, potentially causing operational malfunctions. Regular maintenance, proper installation, and adherence to recommended operating conditions are crucial to mitigate these issues and ensure the reliable and efficient functioning of flanged gate valves.
