Control Valve

ARI-STEVI®

ARI makes a wide range of control valves and actuators. Straight‐through or three‐way control valves with electric or pneumatic actuators are designed in several types and with variable trim options to accurately regulate everything from cold water to aggressive thermal oils.

All of our control valves are available with or without a stainless steel double walled bellows, for leakproof maintenance‐free sealing of high temperature or aggressive media. In addition: rangeability from 30:1 to 50:1, multiple materials, several types of actuators, and an extensive list of control accessories means that no matter your application, we will likely have the perfect solution. If you can't find what you need on this list give us a call, we'd be happy to help you with a customized setup!
