Precision-engineered throttle valve featuring dual-directional flow control through a tapered needle valve system. The chrome-plated brass adjustment knob with 300° rotation allows micro-precision flow tuning. Integrated locking collar prevents accidental setting changes. Special shock-absorbing design maintains stability in high-vibration environments.
- Cylinder speed synchronization in automated assembly lines
- Pneumatic conveyor belt tension control systems
- Injection molding machine ejector timing adjustment
- Robotic arm end-effector damping control
- Semiconductor wafer handling equipment
Installation protocol:
Mount vertically with flow arrow aligned. Always install downstream of cylinder ports.
Perform initial calibration at 0.3 MPa with 3 full open-close cycles. Use Loctite 243
on threads if exposed to continuous vibration. Replace O-rings every 500,000 cycles
in high-cycling applications.
