Gems Sensors & Controls M Specifications
SOLENOID VALVES
M Series – Subminiature
MOPD: 100 PSI (6.9 Bar)
CV Range: 0.018 to 0.070 (KV Range: 0.017 to 0.032)
As Low As 0.5 Watts
The M Series implements efficient power conservation in a solenoid valve that
is specifically designed for sub-miniature two- and three-way pneumatic
and select liquid applications. Field proven to exceed performance
requirements in battery-powered applications, the M Series can be
designed for extreme low wattage conditions. With a compact size,
consistent high-speed response time, and reliable operation over
200 million cycles, the M Series delivers extended performance and
precision flow control in a small lightweight environment.
Typical Applications
Ideal for inline PC interfacing and manifold assemblies:
• Medical and Therapeutic Healthcare
• Clinical Chemistry and Analysis Equipment
• Drop-on-Demand Printing
• Environmental Instrumentation

Notes
1. Barbs are brass.
2. For Stop Port Configuration, must select "0" for valve type 20 (2-way NC) and for type
30 (3-way NC Free Vent).
3. For Stop Port Configuration, must select "1" or "2" or "3" for valve types 22 (2-way
NO), 31 (3-way NC Line Connect), 32 (3-way NO), 33 (3-way MP), and 34 (3-way DC).
Selection "0" can not be used.
4. 2 pins near stop are active.
