IMI Precision, with branches in the US, Mexico and Brazil, has recently introduced a new range of safety valves, through the product brands IMI Norgren and IMI Herion. The SCVA and SCSQ (with integrated “soft start”) are electrically-operated, cross-monitored safety valves.
Designed to render complex machine systems safe in the event of an emergency, the SCVA is a pneumatically-monitored dump valve. It meets the DIN EN ISO 13849 standard and is DGUV certified for category 4 performance level e. The SCVA valve’s very high reverse flow allows downstream air to be exhausted in the shortest possible time, and requires no additional electronic monitoring.
The SCSQ valve has been engineered to provide a controlled restart, or “soft start” of air supply, which can be adjusted to suit the downstream volume and required fill rate. Similar to the SCVA, the SCSQ comes complete with an exhaust silencer. The new valve also meets DIN EN ISO13849 standard, is DGUV certified for category 4 performance level e and meets outstanding B10 values.
