Ball valve for water ARCO 750103 DN15 1/2" female-female SENA VA30 stainless steel lever

ARCO SENA VA30 inline ball valve DN15 1/2" female-female is a stainless steel shut-off valve designed for water systems. The valve features a compact inline body with female threaded connections at both ends and a lever handle for direct manual operation. Constructed from stainless steel, it is intended for potable water distribution, heating circuits and general service lines where a reliable, corrosion-resistant isolation point is required.

Advantages

The stainless steel construction provides corrosion resistance and durability in potable water and heating applications. The compact DN15 size and 1/2" female-female threaded ends allow easy installation into existing piping with compatible fittings. The lever handle gives a clear visual and tactile indication of open or closed position and enables quick shut-off or flow restoration. The inline ball design ensures low pressure drop and tight shut-off when closed.

Suitable for

• Domestic potable water supply lines
• Boiler and radiator shut-off connections
• Service and maintenance isolation in light commercial plumbing
• Small circulation and return piping in heating systems

Key specifications

• Connection type: female threaded at both ends
• Nominal diameter: DN15 (1/2")
• Body material: stainless steel
• Operating mechanism: manual lever with quarter-turn ball
• Application medium: potable water and heating fluids
• Flow characteristic: full bore ball valve for low pressure drop

How to use

Install the valve inline between compatible female-threaded fittings or adapters using appropriate sealing tape or joint compound on the threads. Orient the lever for convenient manual access; the quarter-turn lever moves the ball to open or close the flow. Operate the lever fully to the stop for a reliable seal when closed, and align the lever with the pipe direction for full open flow. Check for leaks after installation and re-tighten connections if necessary following recommended torque values for the piping material.

Usage recommendations

For reliable long-term service, use the valve within typical domestic water temperature and pressure ranges, avoid exposure to aggressive chemicals, and periodically cycle the valve to prevent seizing. When integrating into heating systems, ensure compatibility with the system's pressure and temperature specifications and isolate the valve before maintenance.
