Precision bi-directional flow control valve featuring independent inlet/outlet adjustment knobs with tamper-proof locking nuts. The brass needle valve mechanism ensures smooth flow regulation, while the integrated check valve prevents reverse flow interference. Rated for 2 million cycles with <0.5dB(A) noise reduction design.
- Pneumatic cylinder speed synchronization in automated assembly lines
- Damping control for robotic end-effector grippers
- Vacuum generator exhaust flow regulation
- Medical bed height adjustment mechanisms
- Food packaging machine actuator timing control
Installation protocol:
Always install downstream of lubricator (when used). For optimal performance,
maintain 30cm minimum tubing length between valve and actuator.
Use clockwise rotation for flow reduction (1 full turn = ~35% flow change).
