ARI-STEVI 470/471 Diversity control valves for harsh operating conditions
1）Flexibility
The design of the equipment is very flexible: the stem seal accessories are optional PTFE v-ring PTFE seal graphite seal stainless steel bellows seal, etc. Valve head, stem, threaded seat and other internals can be replaced flexibly; Kvs value can be reduced by up to 6 levels.
2）Durability
Valve stem can extend the service life of equipment and reduce the cost of replacement and maintenance
In addition, the valve head is porous (or parabolic), greatly reducing equipment noise
3）Security
Designed anti-shedding, shaft guide valve head;The design of double corrugated pipe without leakage greatly improves the safety of the equipment
