The AirTAC Airtac 4V Solenoid Valves 4V130C06BG is a genuine 5/3-way 5/3 double solenoid — closed center solenoid valve with 130C06BG 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-06BG is a 5/3-way double solenoid valve in the compact 4V100 body, ordered here with a DC24V coil, terminal-box entry and G1/8 (BSPP parallel) ports. Both sides of a double-acting cylinder or rotary actuator are blocked in the center position, so the actuator stops and holds where it was the moment both coils went dark - handy for pause-and-verify stations. The sliding-column spool responds in 0.05 s or less. Flow sits at Cv 0.51 (8.6 mm2 effective area), sized for double-acting cylinders of roughly Dia16-32 mm at 0.15-0.8 MPa. The valve weighs 200 g, runs dry with no lubrication needed, and carries IP65 (DIN40050) protection. At just 2.8 W the DC24V coil keeps PLC transistor outputs comfortably inside their drive budget, and the body can be stacked on a common manifold base to share one air supply.

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 rotary actuator indexing small parts between stations pauses mid-position while an operator loads a screw. The closed center blocks both actuator ports, and the Cv 0.51 orifice matches the actuator's small volume for crisp 0.05 s switching.
The rig's 24 V DC supply drives the 2.8 W coil through the terminal box with no separate transformer. A Dia16 lift cylinder raises the probe between measurements and the valve parks it exactly where it stopped.
A Dia32 clamp cylinder delivers roughly 41 kgf of push at 0.5 MPa and holds the part during a vision inspection, because the center position keeps both cylinder chambers sealed while the gauge cycle runs.
Every 5/3 version of the 4V100 shares the same Cv 0.51 orifice, so stepping down to the 4V130C-M5 only shrinks the port and tubing, not the flow - pick it for tight micro-manifold plumbing. Move up to the 4V230C closed-center body (Cv 1.0) when a Dia32 cylinder must cycle faster than 3 strokes per second or needs a snappier exhaust. If position holding is not required, the 5/2 4V120 in the same footprint delivers Cv 0.6 and up to 5 cycles/s. Mount a single valve inline, or group valves on a base for a manifold. For a drop-in replacement, match five points: 4V100 body, 30C function, 1/8in port with G thread, DC24V coil, terminal-box entry.
Quick checklist
It is a 5/3-way double solenoid valve, closed center, with Cv 0.51 (8.6 mm2 effective area), a maximum of 3 cycles/s and response of 0.05 s or less. Operating pressure is 0.15-0.8 MPa (proof 1.2 MPa), the DC24V coil draws 2.8 W, ports are G1/8 BSPP, weight is 200 g, and the housing is rated IP65 (DIN40050) for -20 to +70 C.
The center position blocks P, A, B and both exhausts, so a double-acting cylinder stops where it is - but spool leakage over time and any air-supply drop make this a positioning hold, not a safety device. For suspended or fall-hazard loads, add pilot-operated check valves at the cylinder ports or a dedicated mechanical brake; the valve alone should never be relied on as a safety brake.
