Key Features
Exhaust-Air Control
The GRLA design is intended for one-way exhaust-air flow control, allowing the movement speed of suitable pneumatic drives to be adjusted.
G1/8 Thread Connection
The valve uses a G1/8 pneumatic threaded connection for installation on suitable pneumatic components.
QS-4 Push-In Connection
The QS-4 connection is designed for pneumatic tubing with a 4 mm outside diameter.
Adjustable Flow Restriction
A slotted-head adjustment element provides mechanical adjustment of the restricted airflow for application-specific cylinder speed setting.
Compact Pneumatic Control
The combined threaded and push-in connection arrangement supports direct integration into pneumatic drive and tubing systems.
Applications
- Pneumatic cylinder speed control
- Exhaust-air flow adjustment
