Plumbing valve GIACOMINI R730GAX005 – pack of 5, gas valve, 1" connection

Giacomini R730GAX005 is a pack of five gas ball valves intended for use in gas supply and heating systems. Each valve features female-to-female threaded connections with a 1" nominal connection and a full-port ball design that provides minimal flow restriction. The valves are manufactured from nickel-plated brass and are finished with a yellow lever handle intended for gas service. They are EN331:2015 approved and designed for installation by professional plumbers and heating technicians in residential and light commercial systems.

Advantages

The nickel-plated brass construction offers corrosion resistance and mechanical durability while the full-port ball design maintains system flow and reduces pressure drop. Female-to-female threaded ends simplify inline replacement and coupling with existing fittings. The yellow lever handle gives a clear visual indication of gas service and allows quick quarter-turn operation. Supplied as a pack of five, the set provides convenient coverage for multi-point installations or spare-part stocking.

Suitable for

• Installation and replacement in residential gas lines and heating systems
• Light commercial gas installations where EN331:2015 compliance is required
• Service and maintenance tasks requiring compact, full-port shut-off valves
• Plumbing projects that use 1" female threaded connections

When it may not be suitable

These valves are intended specifically for gas applications and have a yellow handle for that purpose; they may not be appropriate for potable water, aggressive chemical services, or high-pressure industrial gas systems beyond typical residential and light commercial ratings. The female-to-female threaded configuration requires compatible mating fittings or adaptors and is not suited for systems that require welded or flanged connections.

Key specifications

• Valve type: ball valve, full port
• Material: brass with nickel plating
• Connection style: female-to-female threaded
• Nominal connection size: 1"
• Handle: yellow lever, quarter-turn operation
• Standards: EN331:2015 approved for gas use

How to use

Verify system is depressurized and gas supply is isolated before beginning work. Ensure thread sealant or compatible gasketing suitable for gas service is applied to male threads of mating fittings. Thread the valve into place using appropriate tools, avoiding excessive torque that could damage the nickel-plated finish or deform the threads. After installation, perform a leak test in accordance with local regulations and the EN331:2015 standard. Operate the yellow lever handle with a quarter-turn to open or close the flow as required.

What to consider before purchase

• Confirm compatibility with the system's thread type and 1" nominal size
• Check that EN331:2015 certification meets local gas installation requirements
• Ensure brass and nickel-plated materials are suitable for the intended service medium
• Plan for necessary fittings or adaptors if mating connection types differ

Usage recommendations

Use trained personnel for installation and testing. Store valves in a dry environment and avoid mechanical damage to threaded ends and handle. Periodically inspect installed valves for signs of corrosion, leakage, or mechanical wear according to maintenance schedules for gas installations.
