One-way flow control valve Festo GR, GRLA
Festo one-way flow control valves for adjusting the speed of pneumatic cylinders. Throttling in one direction, free flow in the reverse direction.
Festo GR and GRLA one-way flow control valves adjust cylinder speed by throttling the air flow in one direction while allowing free flow in the opposite direction.
Two designs
- GRLA – exhaust air flow control. Screwed directly into the valve or cylinder port. This is the usual way to control cylinder speed.
- GR – in-line flow control with push-in connections at both ends.
Technical data
- Housing: reinforced PA (GR models)
- Screw adjustment, lockable
- Flow values in the table are for the throttled direction
