Precision throttle valve optimized for cylinder speed regulation through exhaust flow control. Features dual-scale flow adjustment (rotational + click-stop) with 180° rotation angle and 20 detent positions. The reverse-flow check valve design ensures free flow in supply direction while enabling precise exhaust-side restriction. Corrosion-resistant construction with leak-tight <0.1 mL/min at 0.5 MPa.
- Pneumatic cylinder speed synchronization in assembly lines
- Damping control for vertical load actuators
- Packaging machine clamp force regulation
- Textile machinery tension control systems
- Automated door closure speed adjustment
Installation note:
Install directly at cylinder exhaust ports for optimal response.
For vertical cylinders, position valve below actuator to prevent condensate ingress.
Lubricate adjustment screw quarterly with ISO VG32 pneumatic oil.
