Drain ball valve ARCO 1/2 in with cap model 504220

The ARCO drain ball valve 1/2 in with cap (model 504220) is a compact plumbing valve designed to provide a convenient drain or shut-off point in fluid lines. It uses a quarter-turn ball mechanism for rapid opening and closing and includes a protective cap to prevent contamination and accidental operation. The valve is intended for residential and light commercial applications where a simple, reliable drain point is required.

Advantages

The quarter-turn ball mechanism offers quick and positive flow control with minimal effort and low risk of leakage when closed. Its compact size allows installation in confined spaces and close to fixtures. The included protective cap shields the outlet from dirt and moisture and reduces the chance of accidental activation. The valve's straightforward design simplifies maintenance and replacement compared with more complex drain devices.

Suitable for

• Bathroom and kitchen fixture drains
• Heating system drain points in residential properties
• Cold water distribution manifolds and service lines
• Light commercial plumbing where a basic drain/shut-off is needed

Key specifications

• Connection size: 1/2 inch
• Operation: quarter-turn ball valve
• Material: corrosion-resistant components suitable for potable water systems
• End type: threaded connection for inline installation
• Accessory: removable protective cap included
• Typical pressure handling: suitable for standard domestic water pressure (refer to installation standards for exact limits)

How to use

Install the valve inline using the appropriate threaded fittings and sealing method for the pipe material and application. Turn the handle 90 degrees to open or close the valve rapidly; when closed, the ball mechanism provides a tight shut-off to drain or isolate a section of piping. Use the protective cap to cover the outlet when the valve is not in service to keep debris and moisture out. Follow local plumbing codes and standard installation practices when integrating the valve into a system.

Usage recommendations

For reliable long-term performance, ensure correct thread sealing and avoid over-tightening during installation. Periodically operate the valve to prevent seizing and inspect the protective cap for wear or damage. Do not use the valve for high-temperature steam service or with aggressive chemicals unless confirmed compatible with the valve materials.
