Description

Technical Description – RSV Fast Shutting Gate Valve

The gate valve is equipped with a small gas generator (like those used in cars for safety belt tighteners). When triggered by the control unit, the gas generator produces an enormous amount of gas within a few milliseconds, which drives the valve blade with great force and closes the valve. The blade’s travel is slowed at the end of the stroke. Afterwards, the valve can be slowly re-opened. A manual lock prevents the valve from fast closing during service if the gas generator were to be triggered unexpectedly.
