Precision throttle valve featuring bi-directional flow control with check valve functionality. The chrome-plated brass body ensures corrosion resistance in humid environments. Includes a graduated scale (0–5) for repeatable flow settings and a lock nut to prevent accidental adjustment. Compatible with ISO 8573-1:2010 [7:4:4] compressed air quality standards.
- Cylinder speed regulation in automation assembly lines
- Pneumatic gripper actuation timing control
- Air motor RPM adjustment systems
- Vacuum generator flow optimization
- Medical device pneumatic circuit balancing
Installation guidelines:
Install vertically with flow arrow aligned to system direction. For exhaust
regulation, use in series with silencer. Lubricate threads with PTFE tape
during installation. Perform initial calibration at 0.5MPa pressure.
- Loosen lock nut (2mm wrench)
- Rotate knob clockwise to decrease flow (1 full turn ≈ 2 L/min reduction)
- Counter-clockwise to increase flow (audible click at max position)
- Retighten lock nut while holding knob position
