LO-LOHM HIGH DENSITY INTERFACE (HDI) SOLENOID VALVE

The Lee Company continues to expand its High Density Interface (HDI) platform by now offering more flow capacity without sacrificing size or weight. Imagine the features of a large valve coupled together with the superior performance of a min-iature valve, all in one compact design.

The Lo-Lohm Series solenoid valve sim-plifies the decisions engineers must make when designing valves into their product. Available in three styles (plug-in, face mount, and soft tube ported), this design is ideal for applications where space is limited.

The Lee Company offers an array of standard manifolds for testing as well as custom designed manifold configurations for production. Performance parameters can be optimized for a specific application.

Contact your Lee Sales Engineer for addi-tional technical assistance and application information.
