Precision bidirectional flow control valve featuring micrometer-style adjustment knob with ±5% repeatability. The check valve function allows free flow in one direction while maintaining adjustable restriction in reverse. Nickel-plated body ensures corrosion resistance in humid environments (up to 95% RH non-condensing).
- Speed regulation of pneumatic cylinders in automation lines
- Damping control in vibration-sensitive packaging machinery
- Air flow balancing in multi-circuit systems
- Medical device pneumatic timing controls
- Robotic end-effector pressure regulation
Installation note:
Use 1.5–2 wraps of PTFE tape on male threads. Adjust locknut after flow setting.
Avoid overtightening beyond 1.2N·m torque. For vertical installation, orient adjustment knob upward.
- Linear flow adjustment curve between 30–90% of knob rotation
- Minimal dead zone: ＜3° rotation at fully closed position
- Pressure drop: 0.02MPa at 300L/min flow rate
