Pneumatic roller lever valve

The Festo R-3-1/4-B 8985 is a roller lever valve designed for pneumatic control circuits. It actuates when a moving cam or component depresses the roller, providing a reliable mechanical signal in automated systems. The unit is supplied new in a single pack.

Suits machine builders and maintenance teams

This valve fits builders integrating mechanical limit detection into pneumatic networks and technicians replacing worn actuators on existing Festo installations. It does not suit applications requiring purely electrical switching or electronic position feedback.

G 1/4 port connection

The valve features a G 1/4 pneumatic port that determines compatibility with your tubing and fittings. Verify that your circuit uses this thread standard before ordering.
