Angle valve ARCO A-80 1/2"×1/2" without nut (model NOV06)

ARCO A-80 angle valve 1/2"×1/2" (model NOV06) without nut is a compact shut-off valve designed for controlling water flow in domestic and light commercial plumbing. The valve fits standard 1/2-inch threaded connections and is intended for installation at supply points for faucets, toilets, and other sanitary fixtures where an inline isolation or service shut-off is required. Supplied without a nut, this version is suited for installations that use existing fittings or require a separate compression or coupling piece.

Advantages

The ARCO A-80 provides reliable isolation of water supply lines with a compact form factor that saves space behind fixtures. Its standard connection size ensures compatibility with common plumbing fittings, and the straightforward mechanical design supports easy manual operation for shut-off and partial flow adjustment. The valve’s construction is suitable for typical potable water systems and routine maintenance tasks.

• Shut-off at sink, basin, or lavatory supply lines
• Supply isolation for toilets and bidets

How to use

Before installation, confirm thread compatibility with existing fittings and ensure the water supply is turned off. Fit the valve into the 1/2" connection and secure using appropriate coupling or compression fittings as required by the plumbing system; a separate nut or adapter may be needed since this unit is supplied without a nut. After installation, open and close the valve to verify smooth operation and check all joints for leaks under normal water pressure. Use basic hand tools and follow local plumbing codes during fitting.

Usage recommendations

For long service life, avoid overtightening connections and perform periodic checks for leakage. Where required by installation type, use appropriate sealing tape or approved sealants on threaded joints and select compatible adapters if the original nut is not present. If in doubt, consult a qualified plumber to ensure correct connection and water-tight installation.
