Gate Valve Maintenance

A gate valve opens the flow in a piping system by lifting a rectangular or round gate in the path of the fluid. It is commonly found in applications requiring a free flow or minimal restriction.

A standard gate valve maintenance process includes the following steps:

• A thorough visual inspection for any signs of wear, corrosion, as well as leaks.

• • Checking bolt integrity and ensuring correct valve alignment.

• • Based on the manufacturer’s guidelines, lubricate the valve stem and moving parts.

• • Identify whether there is any sealing surface damage and debris or not. If yes, assess the required disassembly for cleaning or repair.

• • Clean all gate valve components with appropriate tools to remove dirt, rust, or scale. Also, check the valve seat and gate for erosion, damage, repair, or replacement parts.

Furthermore, gate valves might involve a packing gland in some applications, like chemical processing plants. If so, inspect for wear or leakage. Then, adjust or replace the packing material accordingly.
