6592–6595 are large-capacity OPSO valves. They can be mounted on industrial regulators 1391, 1392, 1395, 1492 and 1495 to protect the installation from overpressures generated by regulator malfunction, such as debris on the seat or ice blocking, or re-liquefaction of LPG in the pipes.
6592BM and 6595BM can also provide UPSO safety.
6592 valves can be mounted on 1391, 1392 (except 1392HE) and 1492 (except 1492HE) regulators. 6595 valves can be mounted on 1395 and 1495 regulators.
