The VMPA2‑M1H‑G‑PI is part of Festo’s VMPA valve series, designed as a compact, high‑flow directional control valve suitable for both stand‑alone mounting and integration into VMPA‑type valve terminals. It offers a 5/3 valve function with closed center (5/3 closed), meaning it has three stable positions (typically stay‑in‑center shut‑off) and is operated by an electrical solenoid. The 20 mm valve size and pilot‑operated design provide high‑performance air flow while keeping the valve thin and easy to mount on manifolds and control panels. It is commonly used to control complex pneumatic circuits such as double‑acting cylinders with center‑stop, tool‑changer sequences, or multi‑position actuators in machine tools and automation.
Technically, the VMPA2‑M1H‑G‑PI is powered by a 24 VDC solenoid coil (M1H designation, DC) and operates at an air‑pressure range of –0.09 to 10 bar (vacuum up to ≈0.9 bar partial vacuum, up to 10 bar positive pressure), making it suitable for general‑purpose compressed‑air systems and some vacuum applications. The valve delivers a standard nominal flow rate of approximately 610 l/min (DIN‑1343 standardized), which supports high‑speed actuator motion, and uses a G‑type pneumatic connection (G‑PI) for push‑in‑type or similar fittings at the air ports. The valve employs mechanical‑spring reset and soft‑seal NBR seals in an aluminum die‑cast housing, with built‑in status LEDs and optional manual override for diagnostics and emergency operation. The IP65‑rated electrical interface with an M8‑style plug ensures protection against dust and water jets in industrial environments.
Mechanically, the VMPA2‑M1H‑G‑PI is a flat, metal‑housing valve with a through‑hole mounting pattern, allowing it to be solidly fastened to sub‑base plates and valve racks. It operates in ambient and medium temperatures from –5 °C to +50 °C, using ISO 8573‑1:2010‑compliant compressed air, and is rated for both lubricated and unlubricated service. The ≈100 g weight and compact dimensions (20 mm in width, typical VMPA2 length and height) make it easy to integrate into dense valve fields without excessive bulk. The 5/3‑closed configuration is especially useful for safety‑critical applications where the actuator must be held in a neutral position when the control signal is lost or de‑energized, such as in emergency‑stop sequences or tool‑clamping systems.
