Precision-engineered throttle valve featuring dual-scale flow indicators (0-10 graduations and percentage markings) for fine adjustment in pneumatic systems. The through-port design minimizes pressure loss while maintaining laminar flow characteristics. Includes integrated dust shield for knob protection.
- Speed synchronization in multi-cylinder systems
- Injection molding machine ejector controls
- Conveyor belt tensioning mechanisms
- Food processing pneumatic actuators
- Semiconductor handling robotics
Installation protocol:
Mount vertically with flow arrow aligned to actuator. Perform initial calibration
at 0.5MPa with full-stroke actuator movement. Lubricated air (ISO VG32) recommended
for extended seal life. Requires monthly knob rotation maintenance to prevent sticking.
