Bi-directional flow control valve with integrated check valve functionality, featuring dual-scale flow adjustment (rotational and linear indicators). The corrosion-resistant chrome plating and HNBR seals enable stable performance in high-humidity environments. Requires 5μm filtration for optimal service life.
- Pneumatic cylinder speed regulation in automated assembly lines
- Exhaust air flow control for vibration-sensitive medical equipment
- Packaging machinery with space-constrained installations
- High-cycle automotive testing jigs requiring precise air damping
- Food processing systems needing washdown-resistant components
Adjustment protocol:
Always turn adjustment knob fully clockwise before initial use, then set desired flow by rotating counterclockwise.
Requires 50+ full cycles after installation to achieve rated accuracy.
