6817-SV-3-M5 Festo Front Panel Valve | 3/2 Way Manual Shut-Off
The Festo SV-3-M5 is a compact 3/2-way manual front panel valve. It uses a poppet design with mechanical spring return. Moreover, this valve is monostable and normally closed. A 65 l/min nominal flow keeps cycles fast. In addition, it works from -0.095 MPa to 0.8 MPa. Because the M5 port fits standard pneumatic lines, installation stays simple. Also, a 12 N actuating force gives quick, secure manual control. The body is polymer with brass parts. Furthermore, seals are NBR. This valve suits pneumatic isolation and maintenance operations. Therefore, it is ideal for panel mounting and inline use.

Installation Guide
- Mount the valve in any position.
- Use the through-hole for panel or inline fitting.
- Then connect M5 ports to standard pneumatic lines.
- Keep flow direction non-reversible as marked.
- Also apply 12 N force for manual actuation.
- Finally, check ISO 8573-1:2010 [7:4:4] air quality.
Commissioning and Maintenance
- Verify 0 to 8 bar pressure before use.
- Then inspect NBR seals for wear.
- Clean with LABS-free agents only.
- Moreover, replace the spring return if response slows.
- Check polymer housing for cracks.
- Also confirm brass parts remain tight.
Compatibility
