ARI-STEVI 445/446 Straight through threaded seat control valve
1）Economy and flexibility
Compact design with a threaded option for individual seat replacement and individual valve head replacement based on flexibility considerations reduces KVS. Stem seal can be flexibly selected PTFE v-ring, PTFE seal, graphite seal, stainless steel bellows seal, etc
2）Durability
The precision guide of valve stem can greatly extend the service life of equipment and reduce the cost of replacement and maintenance.
With a 50:1/30:1 adjustment ratio, performance is superior.
3）Security
The sealing ring is pressed by spring to seal the equipment tightly, so as to achieve the safe operation effect without leakage. The level of leakage is up to IV~VI
Double corrugated pipe design is also optional
