Festo GRLA-1/4-QS-6-RS-D One-way Flow Control Valve
Core Features
Product Type:
One-Way Flow Control Valve, used to adjust the one-way air flow speed of pneumatic actuators (such as cylinders) to control the movement speed.
Two-way throttling function is optional (need to confirm the specific model).
Interface Specifications:
Interface Size: 1/4 Inch (G1/4)
Flow Adjustment Range: 0.05~6 L/min (Typical Value, Suitable for Small and Medium-sized Cylinders).
Flow Control Characteristics:
One-Way Throttling: Only restricts air flow in one direction (usually used for cylinder exhaust throttling to achieve smooth movement).
Adjustable: Adjust the flow rate by knob or screwdriver (with scale indication).
High Precision: Stable flow control and reduced actuator jitter.
Material and Design:
Valve Body Material: Brass (nickel-plated for rust prevention) or engineering plastic (chemical corrosion resistance).
Seal Ring: NBR (standard) or FKM (high temperature/oil resistant).
Installation Method: Pipe Installation (direct access to the gas line) or Panel Installation (optional).
Working parameters:
Working pressure: 0.2~10 bar (standard type).
Temperature range: -10°C ~ +60°C (standard sealing material).
Special functions (optional):
With locking function: prevents accidental adjustment (e.g. in vibrating environments).
Quick exhaust (Quick-Speed, QS model): optimizes cylinder response speed.
