Chilled Water Valves

Submersible Solenoid Valves

The MV286A Series cold water valves were developed to provide reliable control for air conditioning chilled water systems.  This innovative design features a durable one-piece polypropylene poppet which provides improved performance, long-term reliability and ease of maintenance.  A manual override is provided in case of a power failure or for manual operation.

Our range of chilled water valves deliver exceptional durability and reliability when compared to other manufacturers’. This is due in no small part to the strict quality controls we implement throughout our processes. Like everything else we manufacture, these chilled water control valves are made to adhere to the highest military standards and requirements.

Our extensive in-house capabilities in engineering, design, analysis, manufacturing and testing ensure these submersible valves will stand up to the harshest conditions and perform at the highest levels.
