LHL Series – 3-Port HDI Solenoid Valve

The LHL Series miniature magnetic latching solenoid valve is designed on the 3-way HDI (High Density Interface) platform and optimized for applications that demand ultra-low power, low heat, and small size.

LHL Series Solenoid Valve

This valve is ideal for compact, battery powered pneumatic instruments such as portable oxygen delivery systems, environmental monitors, breath analyzers and patient simulators. The valve requires only momentary (10 msec minimum) pulses of current to switch its state resulting in 5.5 millijoules consumed per switch.The polarity of voltage on the terminal pins controls the switched position.

DenisDePloeg offers an array of standard manifolds for testing as well as custom designed manifold con- figurations for production. Performance parameters can be optimized for specific applications.
