Precision flow control valve featuring dual-directional adjustment - clockwise for flow restriction, counter-clockwise for free flow. The integrated check valve prevents reverse flow while allowing unrestricted forward movement. Nickel-plated brass construction ensures corrosion resistance in humid environments.
- Cylinder speed regulation in automation lines
- Pneumatic gripper actuation timing control
- Packaging machine air cushion adjustment
- Medical bed height adjustment mechanisms
- Food processing pneumatic conveyor systems
Installation note:
For optimal performance, install with flow arrow aligned to system direction.
Use two wrenches during assembly - one to hold base fitting (24mm wrench size)
and another for final tightening. Lubricate threads with PTFE tape or liquid sealant.
- Clean filter screen every 2,000 operating hours
- Replace O-rings annually or after 500,000 cycles
- Verify flow calibration quarterly using bubble flowmeter
