Submersible Solenoid Valves

Submersible Flow Control

The MV286A Series submersible solenoid 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.
