Description
The Mars 12500 is a 1/4″ 3-way, normally closed (N/C) solenoid valve engineered for dependable air service in demanding HVAC and pneumatic control applications. Designed to handle up to 100 PSI of air pressure and rated for 250VDC operation, this valve delivers precise, responsive flow control wherever it’s needed.
With a normally closed configuration, the valve remains shut in its de-energized state, providing a built-in fail-safe that protects downstream equipment and processes. When energized, the 3-way design allows the valve to direct, divert, or exhaust airflow through its three ports — making it ideal for actuator control, pilot duty, and pneumatic switching circuits.
