Economic Benefits of Using the ROBO Angle Valve
In addition to ensuring operational efficiency and fire safety, the ROBO angle valve provides significant economic value to investors, contractors, and installation teams:
- Reasonable investment cost: ROBO angle valves are competitively priced compared to imported valves in the same segment while fully meeting TCVN technical standards. This makes them an optimal choice for reducing initial material costs without compromising system quality.
- Easy installation and assembly: With standard Rc2 and Rc2 1/2 threads, the valve can be easily connected to common pipes and fittings, shortening installation time, saving labour, and minimising technical errors.
- Durable and low maintenance: Made from ductile iron, stainless steel, and EPDM/NBR rubber, the valve offers high durability, pressure resistance, and corrosion protection. It operates reliably over long periods with minimal maintenance, reducing operational and repair costs.
- Easy replacement and system compatibility: The valve is readily available in the market, compatible with various fire protection devices such as fire hoses, nozzles, and quick couplings, simplifying maintenance and system expansion.
- Enhanced long-term investment efficiency: Thanks to its long service life and stable performance, the ROBO angle valve protects the fire protection system from potential damage, ensures continuous operation, and improves overall reliability and investment effectiveness for the project.
Preparation Before Installation
- Check all valve components, including the handwheel, connectors, and gaskets.
- Ensure that the water pipes and connectors have compatible threads (Rc2 or Rc2 1/2).
- Clean pipes and connection points thoroughly to remove dust, debris, and metal shavings.
Suitable Installation Location
- Valves are typically installed in indoor fire hose cabinets or outdoor fire hydrants.
- Valve orientation can be upward or horizontal, depending on the cabinet or hydrant design.
- Avoid installing in areas with prolonged high humidity, corrosive chemicals, or direct sunlight.
Basic Installation Steps
- Wrap PTFE tape around the pipe threads to ensure a tight seal.
- Hand-tighten the valve onto the threaded pipe, then use a tool to moderately tighten (avoid over-tightening to prevent thread damage).
- Attach the quick connector (adaptor) to the fire hose according to TCVN standards.
- Install the handwheel and check that the opening/closing operation is smooth.
Proper Usage Instructions
- Turn the handwheel counterclockwise to open and clockwise to close.
- After use, close the valve completely, remove the hose, and check for any leaks.
- Avoid applying excessive force to the handwheel or valve body while under water pressure.
Maintenance and Periodic Inspection
- Clean the valve and rotate the handwheel once a month to prevent sticking.
- Check for water leaks at gaskets and threaded connections.
- Perform maintenance immediately if leaks or stiff operation are detected to ensure readiness in emergencies.
