ADVANTAGES AND EQUIPMENT

Safety overpressure shut-off valve OPSO
The OPSO - (Over-Pressure Shut Off) is an automatic safety device that protects connected
devices against excessive high pressure. The outlet pressure is monitored constantly. If the
outlet pressure is exceeded, the OPSO responds and the gas feed is interrupted. The visual
display switches from GREEN to RED.
When it has responded, the OPSO must be opened manually. If the OPSO responds, the
gas feed can be restarted again by following the steps in TROUBLESHOOTING and
"Restarting the safety overpressure shut-off valve OPSO". If an OPSO is installed, the
pressure regulator is also marked "OPSO" on the type label.
