SMC VG342R-5D-06-Q VG342 series 3-way solenoid valve (pilot-operated seat valve, resilient seal)

Q: Can this valve be used in vacuum adsorption applications?

A: Yes. This valve has a pressure range of -0.1 to 0.9 MPa and is compatible with low vacuum environments (-101.2 kPa). Therefore, it can be used for both positive pressure pneumatic control and vacuum adsorption systems as a switching valve for vacuum circuits.

Q: Will it work properly if the system gas source pressure is very low (e.g., below 0.2 MPa)?

A: Note: The VG342R-5D-06-Q is an externally piloted solenoid valve. Its main valve switching depends on the external pilot gas pressure. If the gas source pressure is too low (usually below 0.2 MPa), the pilot valve may not be able to drive the main valve core to switch properly. It is recommended to verify whether the pilot pressure meets the requirements under low-pressure conditions, or consider using an internally piloted derivative model.

Q: My current pipe threads are NPT standard. Can this valve be installed directly?

A: No, it cannot be installed directly. This model's interface thread is Rc 3/4 (Japanese/International tapered thread standard). Although both are tapered threads and NPT (American standard tapered thread), their pitch and taper are different. Directly screwing it in will damage the thread or cause leakage. An adapter (Rc to NPT) is required for compatibility.
