Airtac 4V300 Series Pneumatic Solenoid Valve, 5/3 Way Closed Centre, PT 1/4" Port, Double Solenoid, 220V AC Coils with Connectors, 4V330C08A
Technical overview
The Airtac 4V300 Series provides pilot-operated directional control for pneumatic cylinders and actuators used in automated machinery. Dual 220 V AC solenoids rated at 4.5 VA operate the 5/3-way closed-centre valve, with spring centring to the closed-centre position and a choice of internal or external pilot supply. The valve has PT 1/4" connections, a 0.15 to 0.8 MPa operating pressure range, 1.2 MPa proof pressure, 0.05 seconds or less response time and a maximum switching frequency of 3 cycles/sec. Its aluminum-alloy body is specified for 40-micron filtered air from -20 to 70 °C. Both 220 V AC solenoid coils are supplied with terminal-type connectors for wiring and installation. IP65 coil protection, Class B insulation and lubrication-free operation support reliable service. Typical uses include cylinder control, packaging and assembly machinery, material-handling equipment and pneumatic control panels.
Key Features
- Uses a 5/3-way, closed-centre pilot-operated spool design that blocks airflow in the neutral position.
- Dual 220 V AC solenoids provide electrical actuation in both switching directions.
- Matching terminal-type electrical connectors allow straightforward wiring.
- The PT 1/4" threaded ports allow straight forward connection to the pneumatic circuit.
- Operates within a working pressure range of 0.15 to 0.8 MPa.
- Responds in 0.05 s or less and supports up to 3 cycles/s.
- Return springs centre the spool in the closed position when both solenoids are de-energized.
- The IP65-rated coil is protected against dust and water jets when correctly installed.
Applications
- Mid-position cylinder control
- Actuator stop and hold circuits
- Machine automation systems
- Material handling equipment
- Pneumatic control panels
