ARI-STEVI 450/451Three way control valve with mix and divert function
1）Economy and flexibility
The superior performance adjustment ratio 30:1 can reduce the KVS value; Equipped with 2 threaded mounting seat rings to reduce loss.
Optional for stem sealing :PTFE v-ring, PTFE seal, graphite seal, stainless steel bellows seal, etc
2）Durability
Stable variable valve head guidance can solve the mix and divert of the fluid once. The precision guide of valve stem can greatly extend the service life of equipment and reduce the cost of replacement and maintenance.
3）Security
Double - layer bellows seal to seal the equipment tightly, so as to achieve the safe operation effect without leakage.
