The STEVI VARIO control valve is compact and modular for universal use. Based on a modular design, the configuration adapts to every requirement.
- Maximum durability: stem tightness is guaranteed for millions of operations, with even greater durability thanks to the V-ring PTFE and EPDM packing as well as the metal bellows.
- Optimum installation: the actuator can be rotated through 360º even once the valve is installed in the line.
- Versatile: a wide choice of options thanks to all the variants.
- Accurate and long lasting: no vibration transmitted to the plug even at high differential pressure (thanks to the stem guide), with an optional guided plug as well.
- Easy to install: reduced size and weight.
- Economical: low air and electrical consumption thanks to modern actuator and positioner technology.
A single source: pneumatic actuators (DP), electric actuators (PREMIO-Plus 2G) and digital electro-pneumatic positioners (STEVI-POS), all manufactured by ARI from a single source.
