About the AirTAC 4V430P-15BI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, grommet entry (4V430P15BI)
The AirTAC 4V430P-15BI is a 5/3-way double-solenoid directional valve that, when both coils are de-energised, applies pressure to both cylinder ports simultaneously. This pressure-center configuration is useful for applications where a double-acting cylinder must resist external forces in the mid-stroke position without locking, providing a balanced, pre-loaded state. This specific model is configured for DC24V power with a grommet-style electrical entry, featuring a 0.5 m pre-wired flying lead for direct DIN-connector-free installation.
Built on the largest 4V body, the 4V400 series, this valve provides an effective area of 40.0 mm2 (Cv 2.35) for directing air to larger actuators. It suits pneumatic cylinders in the ~O80-125 mm bore range, with a spool response time of 0.05 seconds or less. The aluminum-alloy body weighs 770 g, operates at 0.15-0.8 MPa, and carries an IP65 protection rating, making it a robust choice for heavy-duty industrial control.

Where the AirTAC 4V430P-15BI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, grommet entry (4V430P15BI) Is Used
Opposing-Force Fixtures
In welding or assembly fixtures, the pressure-center function pre-loads both sides of a large-bore cylinder to hold tooling steady against external pressure or vibration without drifting.
Heavy Part Positioning
Controls O80-125 mm cylinders on large conveyor stops or lift-and-carry stations, where the balanced center pressure prevents the load from sagging when the valve is at rest.
Press Counterbalance
Used in pneumatic press circuits to apply equal pressure to both sides of the ram during idle, providing a soft, pre-loaded state that resists gravity on the tooling.
Is the AirTAC 4V430P-15BI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, grommet entry (4V430P15BI) the Right Valve?
Choose the 4V430P-15BI when you need a 5/3 pressure-center function on a 1/2-inch ported valve with a convenient pre-wired DC24V connection. The pressure-center mode is distinct from closed or exhaust centers; it pressurises both cylinder ports at rest, which can help counteract tooling weight or external process forces without a full lock. If your cylinder is smaller than O80 mm, stepping down to the 4V300 series with its Cv of 1.65 may offer a better size-to-flow match and reduce manifold footprint.
For replacement, match five points: the 4V400 body size, the 5/3 pressure-center function (30P), the 1/2-inch port, a DC24V coil, and the grommet (I) electrical entry. The PT-threaded ports ensure a tight, self-sealing fit with tapered pipe threads. If your flow requirements exceed the 4V400’s capacity, consider a larger valve series or a manifold assembly to handle the demand.
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 4V430P-15BI Solenoid Valve, 5/3-way, pressure center, PT1/2, DC24V, grommet entry (4V430P15BI) FAQ
When both solenoids are de-energised, the valve’s spool moves to the center position and connects the supply port to both cylinder ports (A and B). This applies equal pressure to both sides of a double-acting cylinder, creating a balanced force that resists external loads without a mechanical lock.
The grommet entry provides a 0.5 m flying lead pre-wired to the 3.0 W DC24V coil, eliminating the need for a separate DIN connector. It simplifies wiring in tight spaces and maintains the valve’s IP65 protection rating when properly installed with a suitable cable gland.
