Manual shut-off valve V3V with lock, SKILLAIR® series, without end plates. Its purpose is to separate the working circuit from the supply air. It is a normally closed, three-way valve.

In the resting position (closed), it can be locked with a padlock, which secures the valve from being activated by unauthorized personnel. Size: 100, 200, 300. Supply pressure: up to 15 bar (depending on size). Operating temperature: up to +50°C. Nominal flow: depending on size up to 4700 l/min (at an inlet pressure of 6 bar Δp = 1 bar).
