Product Introduction for New‑Original Festo 196151 MHE2‑MS1H‑3/2O‑M7 Air Solenoid Valve
1. Product Overview
MHE2‑MS1H‑3/2O‑M7 with part‑number 196151 belongs to Festo MHE2 high‑speed miniature poppet‑type solenoid‑valve series, manufactured in Hungary. This is a 3/2‑way monostable normally‑open solenoid valve. Model definition: MS1H means single‑solenoid drive with mechanical‑spring reset; 3/2‑O stands for three‑port two‑position normally‑open function; M7 refers to M7 metric thread for pneumatic ports. It adopts direct‑acting pressure‑relieved poppet‑valve structure. With only 10‑mm installation width and ultra‑fast switching performance, this component controls single‑acting cylinders, vacuum suction cups and small‑size pneumatic actuators on automated assembly fixtures, testing machines and packaging‑equipment. The valve complies with CE, RoHS, c UL us‑Recognized and RCM standards for standard industrial‑workshop environmentsFesto.
2. Main Functions
- Compressed‑air switching control: Air passage keeps open under power‑off state; the internal poppet closes airflow channel when it receives DC24‑V electric signal. It controls retracting action of single‑acting pneumatic parts and vacuum‑generation‑switching.
- Mechanical automatic reset: Precision built‑in spring pushes the valve spool back to the open‑state after power cuts off without extra control‑air supply.
- High‑frequency fast‑switching operation: It achieves rapid on‑off action with maximum switching frequency up to 330 Hz, matching high‑speed‑cycling automated‑production requirements.
- Built‑in protective circuit: The bipolar reverse‑polarity protection and holding‑current reduction circuit prevent coil burnout and lower heating under long‑term energized conditionsFesto.
- Manual override function: Non‑locking push‑type manual button is reserved for manual‑testing during equipment commissioning and daily maintenance.
- Adjustable exhaust‑speed: The exhaust‑port can install throttle mufflers to adjust exhaust‑flow rate for stable‑action control of small‑pneumatic components.

5. Product Advantages
- Ultra‑compact 10‑mm‑width design saves installation‑space for dense‑arranged multi‑valve‑group layout.
- Pressure‑relieved poppet‑valve structure reduces internal friction, extends service‑life for millions‑of‑switching cycles and lowers failure‑rate.
- Built‑in bipolar anti‑reverse‑voltage circuit protects coil from wrong‑wiring damage; the holding‑current‑reduction design effectively reduces coil‑heating.
- Coated zinc‑alloy housing resists workshop oil mist and dust; soft NBR‑HNBR seals avoid internal‑air‑leakage for long‑time continuous‑operation.
- Freely‑selectable installation orientation and standard through‑hole design simplify mounting on fixtures and valve‑bases.
