Description

Draining valve for heating systems, as a flush or filler valve without non-return valve function.

The draining valve inlet is provided with O-ring sealing. During installation, the valve is tightened all the way to the “bottom”. After installation, the valve housing can still be rotated and the drain connection can be placed in any position.

The drain valve requires no maintenance. The installation should be checked regularly.

The drain connection must be fitted with a protective cap when it is not connected to a hose for draining.
