Airtec MO 04 310-HN Valve

Airtec MO-04-310-HN is a compact 3/2‑way solenoid valve with an air‑spring return, configured as normally open (NO) and shipped without a coil (No Coil) for on‑site coil selection. It uses G1/8 (1/8" BSP) porting and delivers up to 360 L/min of flow, with a fast actuation time around 13 ms when energized. The MO variant inverts ports 1 and 3 compared with the NC version, and the coil can be repositioned by 4 x 90° while the plug socket can be rotated 180° to suit tight installations. The body is aluminum and anodized, with seals made of NBR and POM and internal components of aluminum, brass, and stainless steel; the unit is IP65 protected for dust and water spray. Operating temperature ranges from -10°C to +70°C, and the valve is designed for filtered, oil‑free compressed air (ISO 8573‑1 Class 7:2:4). ATEX‑certified variants are available if needed. A manual override is present (detent, screwdriver operated) for manual actuation, and the solenoid coil is field‑reconfigurable in the mounting footprint. This NO MO‑04 valve is well suited for automation panels, pneumatic control in manufacturing, packaging lines, and process environments where a compact, high‑flow, normally‑open valve is required without an included coil.
