About the AirTAC 4V330E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V330E08E)
The AirTAC 4V330E-08E is a 5/3-way double solenoid valve that directs compressed air to double-acting cylinders and actuators, with an exhaust center position that vents both cylinder ports to atmosphere when the valve is at rest. This allows the actuator rod to float freely, making it the go-to choice for manual positioning, safety circuits where pressure must be fully relieved at stop, or applications requiring a cylinder to be moved by an external force without back-pressure resistance.
Built on the 4V300 aluminum-alloy body with 1/4-inch PT (Rc) threaded ports, this valve has an effective area of 21.3 mm² (Cv 1.25) and a maximum cycling speed of 3 cycles per second. The AC24V coil draws 5.0 VA and the spool responds in 0.05 seconds or less. With IP65 protection and a weight of 450 g, it suits ~50-80 mm bore cylinders where a floating center is needed.

Where the AirTAC 4V330E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V330E08E) Is Used
Manual Load Positioning
Ideal for assembly stations where an operator needs to manually slide a fixture or tooling plate into place after the cylinder reaches its mid-stroke. The exhaust center removes all air resistance, allowing smooth, effort-free manual adjustment.
Clamping with Safety Release
Used in clamping systems where the clamp must fully retract and release all pressure at the center position for safe part loading. The exhaust center guarantees no residual energy is stored in the cylinder, preventing accidental clamp activation.
Two-Speed Conveyor Stop
Controls a pneumatic stop gate on a conveyor line. The valve extends the gate to stop a pallet, then shifts to exhaust center to let the pallet push the gate open against no back-pressure, creating a passive, low-impact release.
Is the AirTAC 4V330E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V330E08E) the Right Valve?
Choose the 4V330E-08E when your double-acting cylinder needs to be completely depressurized at the mid-stroke stop, allowing the rod to move without resistance. If you need the cylinder to hold position under load at center, switch to the closed-center 4V330C variant; for a pressure-center application, use the 4V330P. This 5/3 exhaust-center valve is sized between the smaller 4V200 series (Cv 1.0) and the larger 4V400 (Cv 2.82), so it fits cylinders in the ~50-80 mm bore range. When replacing an existing valve, match the 4V300 body, 5/3 exhaust-center function, 1/4-inch port, AC24V coil, terminal box entry, and PT thread to ensure a drop-in fit.
Quick checklist

- ✓ 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 4V330E-08E Solenoid Valve, 5/3-way, exhaust center, PT1/4, AC24V, terminal entry (4V330E08E) FAQ
In the center position, both cylinder ports (A and B) are connected to the exhaust ports, allowing air to escape freely. This means the cylinder rod is not held in place by air pressure and can be moved by an external force, effectively letting the actuator 'float'.
No, the 4V330E-08E is built with an AC24V solenoid that relies on the alternating current's impedance to limit current. Connecting it to a DC supply will cause a short circuit and burn out the coil instantly. You must use a stable AC24V source; for DC control, select the DC24V (B) or DC12V (F) voltage code.
