About the AirTAC 4HV330
The AirTAC 4HV330 is a hand-operated rotary valve on the 4HV300 body with 1/4" or 3/8" ports. It is a 4/3-way valve with a closed center: in the middle position all ports are blocked, so a cylinder stops and holds where it is. The lever turns 45° to each side.
The lever turns lightly with a positive feel and accurate detent positions, and the large flow path keeps pressure loss low. It mounts by the body or through a panel (S; the panel nut is included), and the L version adds a lever lock. It works from 0 to 1.0 MPa on air filtered to 40 µm, -20 to +70 °C, with no lubrication.

Where the 4HV330 Is Used
Manual cylinder control
Moves a double-acting cylinder from a fixture, press or test bench without electrics.
Control panels
Panel-mount versions put the lever on the machine's operator panel.
Locked settings
The L version locks the lever so the position is not changed by accident.
Choosing the Right 4HV330 Configuration
Choose the port size: 08 = 1/4", 10 = 3/8". PT is standard, G (BSPP) is marked G.
Then the mounting: the standard version mounts by its body; S mounts through a control panel and comes with the panel nut.
Finally the lock: L adds a lever lock that holds the selected position; no code means no lock.
AirTAC 4HV330 FAQ

S is panel mounting (nut included); L adds a lever lock. No letter means body mounting, no lock.
