1. General Safety Warnings
Using quick couplings and hydraulic ball valves incorrectly can result in serious injury, equipment failure, or property damage. Please read this safety guide carefully before installation, operation, or maintenance.
Possible Risks:
- High-pressure fluid discharge, leading to injury.
- Equipment failure causing flying parts or leaks.
- Contact with dangerously hot or cold fluids.
- Accidental disconnection, leading to whipping hoses or fluid bursts.
- Fire or explosion in hazardous environments.
2. Selection Guidelines
Before purchasing or installing quick couplings and hydraulic ball valves, consider the following factors:
2.1 Pressure Rating
Ensure the selected product has a pressure rating equal to or higher than the system’s maximum pressure. Pressure surges above the rated pressure can shorten product life and cause failure.
2.2 Fluid Compatibility
Check that the body material, seals, and internal components are compatible with the system’s fluid to avoid deterioration or failure. see Material Options for Different Fluids
2.3 Temperature Range
Ensure the selected coupling or valve can handle the fluid and ambient temperature conditions in the system.
2.4 Environmental Conditions
Consider external factors like UV exposure, moisture, salt water, or chemical exposure. Use protective coatings or materials suited for harsh conditions.
2.5 Connection Type
If the application requires connecting or disconnecting under pressure, use couplings designed for that purpose. Standard couplings may not be safe for pressurized connections.
3. Installation and Handling
Proper installation is critical to ensuring safety and performance.
3.1 Pre-Installation Check
- Inspect couplings and valves for visible damage or defects before installation.
- Ensure all components match system specifications.
3.2 Proper Installation
- Use the correct thread sealant (compatible with system fluid) for threaded connections.
- Do not overtighten fittings to avoid cracking or deformation.
- Ensure all connections are secure before applying system pressure.
3.3 Safe Handling
- Always depressurize the system before connecting or disconnecting couplings.
- Use protective gloves if handling hot or cold fluids.
- Avoid dragging or dropping couplings, which can cause internal damage.
4. Maintenance and Inspection
Regular maintenance helps prevent unexpected failures and prolongs product life.
4.1 Visual Inspections
Inspect couplings and valves regularly for:
- Cracks, corrosion, or visible damage.
- Leaks at connection points.
- Dirt or debris buildup in coupling interfaces.
- Worn-out seals or damaged locking mechanisms.
4.2 Functional Testing
- Periodically operate the system at normal working pressure and check for leaks or malfunctions.
- Test ball valves for smooth operation and full shut-off capability.
4.3 Replacement Intervals
- Replace worn or damaged components immediately.
- Follow manufacturer recommendations for service life and maintenance schedules.
5. Safe Operation Practices
5.1 Avoid Accidental Disconnection
- Use locking mechanisms where necessary to prevent unintended decoupling.
- Do not drag hoses or apply excessive force to couplings.
5.2 Prevent Hose Whip
- Secure hoses properly to prevent uncontrolled movement in case of disconnection.
- Consider using safety cables or hose restraints.
5.3 Fire and Explosion Precautions
- Keep couplings and valves away from open flames and extreme heat sources.
- Avoid using quick couplings in hazardous environments without proper protective measures.
6. Emergency Procedures
In case of an accident:
- Immediately shut down the system and depressurize it.
- Address fluid leaks promptly using appropriate spill containment measures.
- Seek medical attention for any injuries caused by high-pressure fluid injection or burns.
