Safety Devices
Actaris safety shutoff valves (SSV) for applications where redundant safety systems are required, are distinct from the Actaris range of regulators. The security valve offers a positive security in the case of abnormal increase in downstream pressure, when it immediately interrupts the gas flow, and can only be reset manually by a qualified operator. It thus protects the downstream installation from any leakage defect in the regulator. Our safety valves are designed to shut off  if there is excess pressure (OPSO) and also, upon request, if there is a lack of downstream pressure (UPSO).  Further, it increases the safety of the installation by shutting itself off in case of downstream pipe rupture or signal loss in the detection system.
Actaris creep relief valves (SRV) maintain downstream pressure under set value by venting excess gas into the atmosphere, to avoid triggering safety devices by thermal expansion or during transient regimes of regulators.
