The AirTAC Airtac 4V Solenoid Valves 4V130P06F-W is a genuine 5/3-way 5/3 double solenoid — pressure 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 4V130P06F-W is a 5/3-way double-solenoid valve with a pressure-center spool: when both coils are off, the valve rests in its center position with both cylinder ports A and B still connected to supply pressure. That keeps a double-acting cylinder or actuator's two lines live between pulses, which suits circuits where the actuator must stay pressurised on both sides at rest. The -W suffix marks the external-pilot build: pilot air is taken from a dedicated external pilot port rather than tapped from the valve's own inlet, so the spool keeps shifting cleanly even on low main-line pressure or in vacuum-side circuits where an internal-pilot valve would stall.
Flow sits in the small 4V100 5/3 class at 8.6 mm2 effective area (Cv 0.51), with switching up to 3 cycles per second and a response of 0.05 s or less - a good match for double-acting cylinders of roughly O16-32 mm bore. This exact SKU runs on a 12 V DC coil drawing 2.5 W, wired through the built-in terminal box, and uses 1/8-inch PT tapered ports on the aluminium body. The complete valve weighs 200 g.

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.

External pilot feed keeps the spool switching on vacuum lines and processes where main pressure runs well below a standard internal-pilot valve's comfort zone.
12 V DC coil and a pressurised center let a compact rig hold both cylinder lines live between strokes while cycling a test piece at up to 3 cycles per second.
Cv 0.51 flow class pairs well with O16-32 mm bores on grippers, small clamps and indexing slides fed from a filtered 40 um air line at 0.15-0.8 MPa.
Choose this model when your machine works from a 12 V DC supply (battery carts, mobile equipment, low-voltage panels), you need the closed rest state replaced by a pressurised center, and your main air can dip low enough to starve an internal pilot - the -W external pilot removes that dependency. If your cylinder is at the top of the O16-32 mm range or the cycle needs more speed, the 4V200 body with Cv 1.0 is the next size up. Compare the three 5/3 centers before ordering: closed (30C) locks the cylinder, exhaust (30E) lets it float, pressure (30P, this valve) keeps both sides supplied.
Single valve or manifold base both work - the 4V100 body stacks on a common base for multi-valve groups. When replacing, match all five points: body size 4V100, function 30P, port and thread (1/8-inch PT here), coil voltage 12 V DC, and electrical entry (terminal box), plus the external-pilot -W option.
Quick checklist
It is sized for double-acting cylinders and actuators around O16-32 mm bore, with 8.6 mm2 effective area (Cv 0.51) and 3 cycles per second maximum. The -W external-pilot option feeds the pilot from a separate port instead of the valve inlet, so the valve still shifts when main-line pressure is low or on vacuum circuits. Air must be filtered by a 40 um element, and operating pressure is 0.15-0.8 MPa.
With both solenoids off, ports A and B both stay connected to supply pressure, so the double-acting cylinder's two sides remain pressurised in the center position - different from a closed center, which blocks both ports. Note that neither this valve nor any 5/3 center alone is a certified load-holding brake: for suspended loads add a pilot-operated check valve or mechanical brake. This exact model runs a 12 V DC coil at 2.5 W, terminated in the on-board terminal box with PT 1/8-inch threads.
