ARI-STOBU

ARI-STOBU is a isolation valve with gland packing (without bellow), normally used for applications including steam, hot water, process water etc. ARI-STOBU are availabe with flanges, welded and threaded connections in cast iron, ductile iron, carbon steel and stainless steel. Standard version is straight through, but can also be delivered in Y-pattern or angle pattern ARI-STOBU can be fitted with pneumatic or electrical actuator for some types. Globe valves with gland packings are not maintenance free (packing needs adjustments after some time). ARI-STOBU is a globe valve for standard applications compared to ARI-FABA which can handle more complicated applications.
