Warren Controls Three-Way Diverting Control Valve Delivers Long Service Life and High Accuracy for Absorption Chiller

The release announces that Warren Controls has customized a three-way diverting control valve, used in a critical absorption chiller application on a Marine air base in the Southern California desert

Warren Controls, a leading manufacturer of dependable and rugged precision control valves and accessories, has customized a three-way diverting control valve, used in a critical absorption chiller application on a Marine air base in the Southern California desert. This resulted in exceptionally long service life, improved chiller performance and reduced downtime. In service for 16 years, the valve is now being returned to Warren Controls for inspection, rebuild and functional testing to support a tight maintenance schedule.


Part of the Warren Controls industrial valve product line, this 1800 Series product is a 3" flanged three-way diverting control valve pneumatically actuated with an electro-pneumatic positioner for accurate modulating control. Initial feedback from the customer demonstrated the water supply contained calcium and various minerals resulting in scaling of the standard valve trim material. The Warren Controls engineering team customized the valve to include chrome plating on all internal wetted components. Enhancements included treating the valve plug, seat, stem, and cylindrical skirt, with chrome plating to resist scale and mineral deposit buildup. The customized valve helps to keep the absorption chiller operating at maximum efficiency for an extended service life.

The Warren Controls customized 1800 Series Valve is being used in an absorption chiller on the Marine base is part of an upcoming maintenance outage for the entire chiller system. The complete valve assembly will be delivered to Warren Controls for preventative maintenance for the first time in 16 years as part of that planned outage. The Warren Controls engineering and supply team is preparing new chrome-plated wetted parts ahead of time to meet an extremely rapid turnaround schedule for the rebuild and return to the customer for installation.
