How to Properly Store and Maintain Backup Gate Valves

Essential Guide from a Professional Valve Manufacturer

Backup gate valves are crucial for keeping operations reliable in many industries. This includes water treatment plants and oil and gas facilities.

Even the best gate valve can fail early if someone does not store and maintain it correctly during standby times. In this guide, we will show you the best ways to store and care for backup gate valves. These tips come from top industry standards and our own experience in manufacturing.

Why Proper Storage and Maintenance Matters

When not in use, gate valves can suffer from:

• ● Internal corrosion because of moisture

• ● Deformation from poor handling

• ● Sealing failure from hardened elastomers

• ● Running stickiness from lack of movement

These failures can shorten the life of your valve. They can also cause downtime, leaks, and extra costs in emergencies.

Step-by-Step Guide to Properly Store Backup Gate Valves

1. Choose the Right Storage Environment

• ● Location: Store valves in a dry, well-ventilated, and shaded indoor facility. Avoid direct sunlight, rain, and dusty conditions.

• ● Temperature: Ideally, keep storage temperature between -10°C to 30°C (14°F to 86°F).

• ● Humidity: Relative humidity should stay below 60% to prevent corrosion.

• ● Elevation: Place valves on wooden pallets or shelves—never directly on the ground.

"Pro Tip: Use moisture-absorbing desiccants or moisture removers in enclosed storage spaces."

2. Packaging and Protection

• ● Ensure each valve is wrapped in plastic film or anti-rust paper.

• ● Protect flange faces with plastic or rubber caps to avoid impact or deformation.

• ● For automated or actuated valves, cover electrical components with waterproof sheeting.

"Label valves with size, material, pressure rating, and installation position for future ability to follow."

3. Positioning During Storage

• ● Store upright in natural flow direction unless otherwise specified.

• ● Avoid stacking heavy items on top of valves to prevent body or stem deformation.

Maintenance of Backup Gate Valves During Storage

1. Periodic Inspection

• ● Inspect valves every 3–6 months.

• ● Check for surface rust, seal cracks, or physical damage.

• ● Make sure to keep protective covers intact and cover the sealing faces.

2. Valve Operation Testing

• ● Manually rotate the handwheel or stem once every few months to avoid internal jamming.

• ● For motorized valves, perform a dry run if possible.

3. Lubrication and Sealing

• ● Apply fresh grease to stem threads and moving parts during inspection.

• ● If your valve has elastomer seals, ensure they are not dry or brittle. Replace the component if deemed necessary.

4. Reapply Anti-Corrosion Treatment

• ● Wipe the valve body clean and reapply anti-rust oil to exposed metal surfaces.

• ● If stored longer than one year, consider removing old lubricant and replacing it entirely.

Pre-Installation Checklist

Before placing a stored valve into operation:

• ● Conduct a hydrostatic test.

• ● Remove all packaging and clean flange surfaces.

• ● Check that the valve fully opens and closes without resistance.

• ● Ensure no part of the valve has deformed or corroded.

Documentation and Tracking

• ● Maintain a maintenance log for each valve in storage.

• ● Record the date of inspection, findings, lubrication activities, and test results.

• ● Track the total storage time—generally, we recommend installing stored valves within 18–24 months for best performance.

Long-Term Storage Recommendations

For valves that need to be stored beyond 2 years:

• ● Perform a complete visual inspection annually.

• ● Replace all rubber-like components after 2 years of idle time.

• ● Consider partial disassembly for deep internal inspection if feasible.
