About the AirTAC 4V430C-15EI Solenoid Valve, 5/3-way, closed center, PT1/2, AC24V, grommet entry (4V430C15EI)
This 4V430C-15EI is a 5/3-way double-solenoid valve built on AirTAC’s largest 4V body, configured with an AC24V coil and a grommet-style electrical entry with a 0.5 m flying lead. When both solenoids are de-energised the spool returns to the closed center, blocking all ports so a double-acting cylinder holds its position under load. The 5/3 body yields an effective area of 40.0 mm² (Cv 2.35) and a maximum cycling rate of 3 cycles per second, suiting pneumatic systems with bores in the ~Ø80–125 mm range.
At 770 g the valve is compact for its flow class, yet the aluminium-alloy body and IP65-rated enclosure stand up to demanding factory conditions. The AC24V coil draws 5.0 VA, and the sliding-column design responds in 0.05 s or less, giving crisp mid-stop control on presses, clamps, and vertical lift assists where holding at center is the primary requirement.

Where the AirTAC 4V430C-15EI Solenoid Valve, 5/3-way, closed center, PT1/2, AC24V, grommet entry (4V430C15EI) Is Used
Press & Clamp Mid-Stop
On a pneumatic toggle press the 4V430C-15EI halts the tool at an intermediate position before final advance, holding it firmly while the operator aligns the part. The closed center blocks cylinder ports so the ram does not drift under tool weight.
Pallet Lift & Hold
A pallet lift on a conveyor line uses this valve to stop the platform at a mid-level transfer height. De-energising both solenoids locks the lift in place, allowing a roller bed to engage without the platform sinking.
Material Gate Diverter
Large material-handling gates on a hopper outlet are positioned to a partial-open setpoint by the 4V430C-15EI. The closed-center spool holds the gate steady against material head pressure, giving repeatable batch metering.
Is the AirTAC 4V430C-15EI Solenoid Valve, 5/3-way, closed center, PT1/2, AC24V, grommet entry (4V430C15EI) the Right Valve?
Choose the 4V430C-15EI when your circuit needs a double-acting cylinder to stop and hold firmly at an intermediate position—the closed-center spool traps air on both sides of the piston. For smaller cylinders (roughly Ø63 and below) the 4V300 series (Cv 1.65) is usually a better match, keeping response crisp without oversizing the valve. Because the 4V400 is the largest body in the 4V family, applications needing still higher flow should look to a larger valve series or a manifolded group.
When replacing an existing valve, match five points: body size (4V400), function (5/3 closed-center, code 30C), port and thread (1/2 in PT), coil voltage (AC24V), and electrical entry (grommet with flying lead). The AC24V supply is common in panels with control transformers, and the pre-wired grommet entry saves installing a separate connector, speeding up wiring on multi-station machines.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)
- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or manifold base?
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.8 MPa operating pressure.
- check Match coil voltage to your controller output.
- check Use the manual override to test before powering.
- check Fit silencers or fittings to the exhaust ports.
- check Wiring by qualified personnel per AirTAC docs.
AirTAC 4V430C-15EI Solenoid Valve, 5/3-way, closed center, PT1/2, AC24V, grommet entry (4V430C15EI) FAQ
With a 5/3 effective area of 40.0 mm² (Cv 2.35) the valve is sized for double-acting cylinders roughly in the Ø80–125 mm bore range. It cycles at up to 3 times per second, so it covers both moderate-speed positioning and holding applications on larger actuators.
If both solenoids lose power the spool springs to the center position where all cylinder ports are blocked. The piston stops and is held by trapped air pressure. Note that this is not a safety-rated load-holding device—for suspended or vertical loads that must not drift, add a pilot-operated check valve or mechanical brake at the cylinder.
