Ball valve straight half-union 3/4" female-thread to 1" male-thread lever stainless steel ARCO VA30

Straight half-union ball valve ARCO VA30 in stainless steel provides a compact, detachable connection for fluid shut-off and flow control. One end has a 3/4" female thread and the other a 1" male thread, allowing connection between mismatched threaded fittings. The lever handle offers quick quarter-turn operation and clear visual feedback on open/closed position. The stainless steel construction resists corrosion and is intended for use in residential and light commercial water installations where a compact, serviceable valve is required.

Advantages

The half-union design enables easy removal and maintenance of the valve without disturbing the adjoining piping. Stainless steel body and internal components provide corrosion resistance and durability in typical potable water and utility applications. The lever handle delivers fast, reliable quarter-turn operation and simple indication of valve position. Threaded connections simplify installation and compatibility with existing plumbing fittings of the specified thread sizes.

Suitable for

• Residential water supply shut-off and control
• Light commercial plumbing systems and utility lines
• Situations requiring a removable inline valve for maintenance
• Connecting plumbing components with 3/4" female to 1" male threaded interfaces

Key specifications

• Valve type: straight ball valve with half-union
• Body material: stainless steel
• End connections: 3/4" female thread on one end, 1" male thread on the other
• Actuation: manual lever handle, quarter-turn operation
• Application: potable water and general utility plumbing
• Design: compact inline for tight installation spaces

How to use

Ensure the pipeline is depressurized before installing or removing the half-union ball valve. Apply appropriate thread sealing compound or tape to the male thread to achieve a leak-tight connection, then hand-tighten and secure with a suitable wrench without over-torquing stainless steel fittings. Operate the lever handle through a 90° turn to open or close the valve; the handle aligns with flow when open and is perpendicular when closed. For removal, loosen the union nut portion of the valve to detach the body while leaving the piping intact.

Usage recommendations

For long service life, avoid exposing the valve to aggressive chemicals outside typical potable water systems and perform periodic inspections for leaks or wear. Use compatible thread sealant and avoid excessive torque during installation to prevent thread damage. If used in outdoor or exposed locations, consider additional protection against environmental contamination.
