Control and Isolation

The alkylation process involves tight isolation and precise control to ensure that the proper ratios of Olefins, IsoButane and Hydrofluoric Acid are used in the reactor and other vessels. Hydrofluoric acid is an extremely dangerous chemical as it is highly corrosive and carries a health and safety risk to all personnel. Due to hydrofluoric acid’s high corrosiveness and health and safety impact, the need for a very reliable, well-constructed isolation valve and actuator for physical containment are paramount as these valves need to be in operation without failure for years. 

Sterling Valve and Automation’s emergency shutdown technologies provide the required valve material to meet the extreme health and safety concerns of this process as well as providing quick, reliable, precise fail safe operation. Our automated emergency shutdown solution provides protection of the plants equipment, reduces downtime, and potential loss of life. 

Using the highest quality materials and decades of design refinement El-O-Matic™ actuators reliably and efficiently operate quarter-turn mechanisms. Extreme temperature and high cycle applications pose no problem for the robust design of El-O-Matic™ actuators.
Designed, engineered, and manufactured in Germany for over 30 years, all Zwick valves are state-of-the-art and customizable to sizes greater than 88” to meet all your critical service requirements.
