## Long description

ARCO drain valve with a 3/4" G male threaded connection and a 20 mm nominal diameter is a compact metal valve designed for controlled draining and isolation in plumbing and heating systems. The valve provides a simple threaded drain or bleed point for radiators, boilers, pipes and service lines where a straightforward, durable shut-off or release is required.

Key specifications

Nominal diameter: 20 mm
Material: metal construction suitable for plumbing and heating use
Function: manual drain/bleed valve for controlled discharge or isolation

How to use
Shut down the system and relieve pressure before installation or operation. Thread the valve into the corresponding female fitting or outlet until properly seated and sealed with suitable thread sealant or tape if required. To drain or bleed, open the valve spindle slowly to control the flow; close the valve fully when the desired level or empty state is reached. After use, verify the connection for tightness and restore system pressure gradually according to the system manufacturer's instructions.
Usage recommendations
Install the valve in accessible locations and use compatible fittings to avoid leaks. Regularly inspect for corrosion or wear, especially in systems with aggressive water chemistry, and replace the valve if threads or sealing surfaces degrade. Follow local plumbing codes and safety procedures when performing maintenance or draining pressure systems.
