Savety valves

SV-L1 | SV-H1

Valves for protection against pressure rise.

A safety valve is a valve which opens automatically to prevent a predetermined gauge pressure being exceeded and which recloses after decrease in pressure. Intended as a safety device against impermissible excess pressure in stationary and mobile pressurized gas containers. In closed rooms, blow-off lines must be led from all safety valves to the outside, and robecco gas warning systems must be installed. Each robecco safety valve is delivered with a valid acceptance certificate from the ZÜS. (Zugelassene Überwachungsstelle)
