Ball valve RED R023404001, 1/2" threaded, water valve with butterfly stem seal

RED ball valve R023404001 is a 1/2" threaded water shut-off valve designed for plumbing systems that require a compact, reliable isolation fitting. The valve uses a spherical closure element to control flow and a butterfly-style stem seal to minimise leakage and provide a tighter shut-off compared with standard stem designs. It is suitable for domestic and light commercial water supply lines where a threaded connection and straightforward operation are preferred.

Advantages

The ball mechanism provides precise on/off control with low pressure drop when fully open. The butterfly-style stem seal reduces the risk of external leakage at the stem and contributes to longer-term sealing performance. Threaded connection simplifies installation on existing pipework and allows easy replacement without soldering or flaring. The compact form factor is practical in confined spaces and serviceable for routine maintenance.

Suitable for

• Domestic cold and hot water supply lines
• Shut-off isolation for appliances and fixtures
• Light commercial plumbing systems
• Retrofitting or replacing threaded valves in existing installations

Key specifications

• Connection type: 1/2" threaded
• Valve type: ball valve with spherical closure element
• Stem sealing: butterfly-style stem seal
• Intended medium: water (cold and hot domestic water)
• Typical installation location: inline shut-off in supply lines

How to use

Shut off the upstream supply before installing or servicing the valve. Thread the valve into matching 1/2" female fittings using appropriate thread sealant (PTFE tape or approved pipe joint compound) to ensure a leak-free joint. Operate the valve by turning the handle 90 degrees from open to closed; the ball mechanism gives a clear on/off position. For service, isolate the section of pipe and relieve pressure before removing the valve.

Usage recommendations

Use compatible thread sealants and avoid over-tightening to prevent thread damage. Verify operating temperature and pressure limits of the installation environment and flush the line of debris before commissioning to reduce wear on the ball and seats.
