Proper storage is the single most important factor to guarantee a backup gate valve will function flawlessly. The core principle of proper storage and maintenance is to prevent corrosion, deformation, and seal failure. The best ways to store and care for backup gate valves focus on controlling the environment. Technicians who properly store a gate valve protect the asset. Following the right environmental conditions for storing helps maintain backup gate valves for long-term readiness.
DO ✅: Always store in dry areas on pallets or shelves.
DON'T ❌: Never leave backup gate valves on the ground or exposed to weather.
Pre-Storage Preparation: Setting Your Backup Gate Valves Up for Success
Proper preparation before storage is a non-negotiable step. It directly impacts the long-term readiness of backup gate valves. A proactive approach prevents degradation and ensures the equipment is ready for immediate deployment. Following a clear pre-storage checklist helps technicians maintain backup gate valves effectively.
DO: Clean and Inspect Before Shelving
A technician should never store a dirty or damaged valve. A thorough cleaning and inspection process is the first line of defense against corrosion and seizure. Mechanical cleaning with tools like wire brushes removes solid contaminants such as scale or weld slag. For grease, oil, or other residues, aqueous or solvent cleaning is highly effective.
An inspector must then check the valve body for any cracks, dents, or signs of wear. They should also examine sealing surfaces for imperfections that could compromise performance. Any identified damage requires repair or replacement before the valve is approved for storage.
DO: Lubricate and Cycle the Valve
Lubrication protects against corrosion and ensures smooth operation. Technicians should lubricate moving parts according to manufacturer specifications. This typically involves applying a high-quality grease to the stem threads and other operational components. A thin coat of anti-rust oil on exposed metal surfaces, especially flange faces, provides an excellent barrier against moisture.
After lubrication, it is critical to cycle the valve. Opening and closing the gate a few times distributes the lubricant evenly and confirms the valve operates freely without binding.
DO: Close the Gate and Seal All Ports
A valve should be stored in the fully closed position. This protects the gate and seats from airborne dust, debris, and accidental impact. Sealing all openings is the final preparatory step. Technicians must protect flange faces with sturdy plastic or rubber covers to prevent scratches or deformation.
Pro Tip: Whenever possible, use original packaging and protective covers supplied by the manufacturer. These materials are specifically designed to shield the valve during transport and storage.
Wrapping the entire valve in plastic film or anti-rust paper offers an additional layer of protection. For actuated valves, waterproof sheeting should cover any electrical components to prevent moisture ingress.
DON'T: Store a Dirty or Damaged Valve
Placing a dirty or damaged valve into storage is a critical mistake. This action directly undermines the purpose of maintaining ready-to-use backup gate valves and often leads to future operational problems, increased costs, and potential system failure.
Increased Energy Consumption: Solid buildup can hinder full gate travel and increase operating torque.
Actuator and Handle Resistance: Internal contamination often results in difficult manual or automated operation.
Internal Part Damage: Foreign objects can damage seats and cause leakage.
System Contamination: Residual debris may contaminate downstream equipment.
Issues such as corrosion and rust will only worsen over time. Cast iron and carbon steel valves are particularly vulnerable in humid environments. Storing a damaged valve is effectively storing a future liability.
The Rules of Proper Storage and Maintenance
Once a valve is cleaned, inspected, and prepared, the focus shifts to the long-term holding environment. Effective storage environment control is the difference between a reliable asset and a future operational failure.
DO: Control the Environment
Technicians must select an indoor, climate-controlled warehouse. The space should be clean, dry, and free from corrosive fumes, vibration, and excessive dust.
Exposure to ultraviolet (UV) light can accelerate material degradation. Many industrial coatings and elastomeric seals perform best when protected from direct sunlight.
Note: A stable environment minimizes condensation caused by temperature fluctuations and significantly reduces corrosion risk.
DO: Position Valves Correctly
How a valve is positioned during storage matters. Technicians should follow specific orientation guidelines to prevent stem sag, body deformation, or seat damage.
For large-diameter backup gate valves, vertical storage with flange support is recommended to avoid structural stress.
DON'T: Store Directly on the Ground
Valves should always be elevated on pallets or shelving. Concrete floors can transmit moisture, accelerating corrosion on valve bodies and flanges.
DON'T: Mix Metals Improperly
Galvanic corrosion is an electrochemical reaction that occurs when dissimilar metals come into contact in the presence of moisture. Proper separation using non-conductive materials is essential.
How to Maintain Backup Gate Valves During and After Storage
Proactive maintenance practices during storage ensure valves remain ready for reliable service when needed.
DO: Perform Regular Inspections
Stored valves should be inspected quarterly for signs of corrosion, damage, or lubricant degradation. Periodic operation helps prevent seizure.
DO: Keep Detailed Storage Logs
Accurate records of inspection, lubrication, and handling history support effective asset management and long-term reliability.
DON'T: Skip the Pre-Installation Check
Before installation, technicians must inspect and function-test each valve to confirm it remains in proper working condition after storage.
Technicians who follow these dos and don’ts make a low-cost investment in operational reliability. A properly stored gate valve is a facility’s assurance of safety and readiness when it matters most.
FAQ
How often should a technician inspect a stored valve?
At least quarterly, with annual comprehensive inspections for long-term storage.
Why is storing a valve in the closed position important?
It protects internal sealing surfaces from dust, debris, and accidental damage.
Can a technician store valves outdoors if covered?
No. Outdoor storage exposes valves to humidity, UV radiation, and temperature fluctuations.
What is the biggest risk of storing valves on a concrete floor?
Moisture absorption from concrete accelerates corrosion and shortens valve service life.
