The AirTAC Airtac 4V Solenoid Valves 4V130C06EG-W is a genuine 5/3-way 5/3 double solenoid — closed center solenoid valve with W ports and an effective area of 8.6 mm² (Cv 0.51). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The AirTAC 4V130C-06EG-W is a 5/3-way closed-center solenoid valve built on the compact 4V100 aluminum body, wired for AC24V through a terminal-box entry with G (BSPP parallel) 1/8 ports. In the center position both cylinder ports are blocked, so a double-acting actuator stops and holds where it was when the last pulse ended. Energising either solenoid sends air to one side of the cylinder while venting the other; de-energising both coils parks the spool in the blocked center. Flow sits in the small-body class: 8.6 mm2 effective area, Cv 0.51, with a maximum cycling rate of 3 cycles per second, which matches the ~Dia16-32 mm double-acting cylinders this body suits. The AC24V coil draws 4.0 VA and the whole valve weighs 200 g, yet it still responds in 0.05 s or less, carries an IP65 (DIN40050) rating and mounts on a base for an integrated manifold group. Closing position with two blocked ports is a motion-park function, not a certified brake - for suspended loads add pilot-operated checks at the cylinder ports or a mechanical brake.

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

A Dia20 mm double-acting clamp cylinder on an electronics test fixture stops mid-stroke when both coils drop out; the closed center blocks both ports and the 0.05 s response keeps the press cycle crisp.
On a small educational or lab pick-and-place, the Z-axis Dia16 mm cylinder parks at a set height between picks. Cv 0.51 flow is matched to the short stroke, and the blocked center holds the slide against gravity drift between moves.
A Dia25 mm gate cylinder indexes cartons on a packaging line and must hold position whenever the 24 V control circuit drops. The 4V130C-06EG-W's AC24V coil connects directly to the machine's control transformer with no extra supply.
Size in both directions. Step down within the same body to the 4V130C-M5, whose M5 ports suit mini cylinders and short lines when 1/8 ports are more flow than you need. Step up to the 4V200 family (4V230C, Cv 1.0) if your cylinder is above ~Dia32 mm or the stroke must complete faster than this valve's 3 cycles per second allows. Closed center (30C) is the right 5/3 choice when the load must stop and stay put; choose 30E if the actuator should float, or 30P if both sides should stay pressured. This SKU is AC24V, terminal box, G thread - match all five points when replacing: 4V100 body, 30C function, 1/8 port with G (BSPP) thread, AC24V coil, terminal entry. A single valve with piping suits one-off machines; a base-mounted manifold group saves wiring and tubing on multi-valve panels.
Quick checklist
5/3-way closed center, double solenoid, 1/8 in G (BSPP) ports, AC24V coil at 4.0 VA, terminal-box entry. Flow: 8.6 mm2 effective area, Cv 0.51, max 3 cycles per second. Operating pressure 0.15-0.8 MPa (proof 1.2 MPa), response 0.05 s or less, temperature -20 to +70 C, IP65, aluminum body, 200 g weight, 40 um filtration, no lubrication needed. It directs air to double-acting cylinders in the ~Dia16-32 mm range.
It parks a double-acting cylinder by blocking both ports, which resists drift in normal duty - but spool leakage and pressure imbalance mean it is not a certified brake. For suspended loads or any fall-protection duty, fit pilot-operated check valves at the cylinder ports or a mechanical brake, and treat the 4V130C as the directional control only.
