ARI STEVI® Vario 448 / 449 Compact Control Valves

The STEVI Vario is a variable, compact control valve for universal applications. It is based on a modular system, which means that the configuration is adaptable to the task at hand.

• Optimum handling: actuator can be rotated 360°.

• Flexible: changeable, variable trim (at least 4 Kvs values as well as multiple flow characteristics and plug designs).

• Precise and durable: vibration is prevented even at high differential pressures (stable shaft guiding).

• Easy handling: small footprint and reduced weight (low height).

• Economical: very low air consumption (smaller pneumatic actuators possible).
