AIRTAC 4H310-08/10, 4H330C-08/10, 4H330E-08/10 4H Series 5/2 way, 5/3 way Hand Lever Valve 1/4", 3/8"
AIRTAC 4H310-08/10, 4H330C-08/10, 4H330E-08/10 4H Series 5/2 way, 5/3 way Hand Lever Valve 1/4", 3/8"
The AIRTAC 4H Series Hand Lever Valve is a manually operated pneumatic directional control valve designed for precise airflow management in industrial automation systems. This series includes both 5/2-way and 5/3-way configurations, with models differentiated by their center position functions—such as closed center, exhaust center, or pressure center—to accommodate various control needs for double-acting actuators. Key specifications include an operating pressure range of 0 to 1.0 MPa, a proof pressure of 1.5 MPa, and a temperature tolerance from -20 to +70°C. Constructed with an aluminum alloy body and a sliding column structure, these valves ensure excellent sealing, lightweight properties, and easy installation. They operate without requiring lubrication and are designed for panel mounting, providing reliable performance in applications like machinery control and pneumatic tool operation.

[Note1] PT thread, G thread and NPT thread are available;
[Note2] Once lubricated air is used, continue with same medium to optimise valve life span. It is suggested to use ISo VG32 lubricant or the oil with the same grade.
[Note3] Equivalent orifice S and Cv are all calculated from the flow rate data.
