Ball valve for water ARCO DN20 3/4" G male-female SENA VA30 lever Inox

ARCO SENA VA30 ball valve DN20 (3/4") with G male-to-female threaded connections and an Inox stainless steel lever is designed for reliable on/off control of water flow. The valve body and internal components are engineered for use in domestic and light commercial plumbing systems where a compact, threaded shut-off is needed. Its DN20 size corresponds to standard 3/4" pipe fittings, enabling straightforward installation in service lines, branch circuits, and equipment connections.

Advantages

The ARCO SENA VA30 combines corrosion resistance with mechanical durability thanks to stainless steel lever construction and compatible valve materials. Threaded male-female G connections provide a secure, leak-minimizing joint that simplifies replacement and maintenance. The lever operation offers quick visual indication of open or closed position and allows fast manual actuation without tools. Designed for water service, the valve delivers consistent sealing performance for shut-off tasks.

Suitable for

• Domestic water shut-off and branch connections
• Service lines and maintenance isolation points
• Light commercial plumbing and HVAC secondary circuits
• Equipment connections requiring a threaded 3/4" valve

Key specifications

• Nominal diameter: DN20 (3/4")
• Connection type: G male-to-female threaded
• Actuation: manual lever (stainless steel/Inox)
• Media: water (potable and non-potable applications consistent with material compatibility)
• Function: two-way on/off ball valve

How to use

Install the valve inline with matching DN20 (3/4") G threaded fittings, ensuring thread sealant or PTFE tape is applied according to local plumbing practice to prevent leaks. Orient the valve so the lever is accessible for operation and verify flow direction if markings are present. Operate the lever 90° to switch between open and closed positions; perform a visual check after installation and cycle the valve to confirm smooth action and tight shut-off.

Usage recommendations

Use the valve within typical residential and light commercial water system pressures and temperatures. Avoid overtightening during installation to prevent thread damage; inspect seals periodically and exercise the lever occasionally to prevent seizing. For applications involving aggressive chemicals, high temperature, or pressures beyond standard water systems, consult material compatibility and system specifications before use.
