ARI® SAFE 12.901 Full Lift Safety Valve PN16 DN20/32
Automatic overpressure protection with full lift discharge for critical steam and gas systems.
ARI SAFE 12.901 Full Lift Safety Valve PN16 DN20/32 provides automatic protection against excessive pressure in critical systems. In addition, the spring-loaded mechanism opens instantly when pressure exceeds the set value, therefore discharging excess pressure under controlled conditions. Constructed with an EN-JL1040 cast iron body and 1.4571 stainless steel internals, it withstands demanding industrial service.
The valve performs a full lift when the pressure set value is exceeded, thereby achieving maximum flow discharge. Furthermore, it closes automatically when system pressure returns to normal, and tight sealing is guaranteed. It operates safely in steam and gas lines up to 300°C. The flanged connection simplifies installation and maintenance, which reduces downtime.
