Ball valve ARCO VA30 1/2" female thread with drain and air vent, lever handle, stainless steel

Ball valve ARCO VA30 1/2" female thread with drain and air vent is a stainless steel shut-off valve designed for water installations. The valve combines a standard 1/2" female threaded inlet/outlet with an integrated drain port and an air vent, and is operated by a lever handle to provide quick manual control. It is intended for use where reliable isolation, controlled draining and removal of trapped air are required in plumbing and heating systems.

Advantages

The valve’s stainless steel construction offers corrosion resistance suitable for potable water and heating circuits. The integrated drain allows controlled emptying of isolated sections without disassembly, while the air vent helps remove trapped air to improve system performance. The lever handle provides clear visual position indication and fast operation, and the compact design saves installation space in confined manifolds and pipe runs.

Suitable for

• Residential and commercial water supply lines
• Heating systems and radiator circuits
• Service and maintenance isolation with controlled draining
• Manifolds and compact installations where air venting is needed

Key specifications

• Connection type: 1/2" female threaded inlet and outlet
• Body material: stainless steel
• Actuation: manual lever handle
• Integrated functions: drain port and air vent
• Application media: potable water and heating fluid
• Typical installation orientation: inline with drain accessible

How to use

Install the valve into the pipeline using the 1/2" female threaded connections, ensuring appropriate sealing material and correct orientation so the drain port is accessible. Use the lever handle to open or close the valve: turn the handle 90° to switch between fully open and fully closed positions. To drain a section, close the main flow, open the integrated drain valve and allow the isolated section to empty into a suitable receptacle or drain. To vent trapped air, slightly operate the air vent according to system pressure and manufacturer guidance, taking care to avoid sudden releases of hot fluid under pressure.

Usage recommendations

For safe and reliable operation, verify system pressure compatibility before installation, use thread sealant appropriate for potable water if required, and ensure the drain outlet is routed to a safe discharge point. Periodically operate the lever and drain to prevent seizing and check the valve for signs of wear or corrosion during scheduled maintenance.
