Swivel Lever Valve for Test Equipment

The Festo RW/O-3-1/8 is a swivel lever valve designed for pneumatic test equipment setups. It provides manual flow control via a rotating lever mechanism. The G1/8 port thread allows direct connection to standard pneumatic fittings. This component suits technicians building or maintaining compressed air test rigs.

Sustained Operation Characteristics

The valve body is constructed to handle continuous pneumatic pressure during extended testing cycles. Its sealing design maintains integrity under constant load without drift. The lever action requires consistent force regardless of duration. Red finish aids visual identification in complex assemblies.

Replacement And Upgrade Context

This valve replaces worn or leaking G1/8 swivel lever units in existing Festo test benches. The jump is justified when seal degradation causes pressure loss during long tests. It is not suited for automated actuation needs requiring solenoid control. Buyers needing electrical switching should specify a different valve type.

Questions about this item

How much heat or noise does the RW/O-3-1/8 swivel lever valve generate during continuous daily operation?

As a pneumatic valve with no motor or fan, it produces no measurable heat or audible noise during normal use.

What pneumatic fittings or tubing must I already have to connect the G1/8 ports on this valve?

You need standard G1/8 threaded fittings and compatible tubing rated for your system pressure.

Will the RW/O-3-1/8 valve work reliably alongside older Festo cylinders and tubing already installed on my bench?

Yes, the G1/8 thread and standard pneumatic interface match legacy Festo components, so it integrates without adapters.
