Model Category


ARI-STEVI 472 High-performance and variable control valve 
1）Flexibility
The design of the equipment is very flexible: the valve body is made of cast steel and heat-resistant cast steel (up to 550°C) with a choice of flange or butt joint; The valve head can be flexibly replaced with a parabolic cage valve head (which can greatly reduce noise) or an efficient balancing valve head (which can increase efficiency in the selection of actuators).Up to 5 levels of KVS values can be reduced.
2）Durability
The reinforced design of the valve head with double guide can withstand higher pressure difference (This is standard configuration for valves with size larger than DN80), and the extended bonnet makes the equipment more durable; High wear resistance is based on the stellite enhanced sealing area.
3）Universality
The versatility is based on the modular system design, available with more than ten types of electric or pneumatic actuators. Realize the best adjustment performance based on linear or equal percentage adjustment characteristics.
