How do I adjust the flow on the MRF OTC Compact "O" Series Pneumatic Plastic Throttle Valve for Actuator using a screwdriver?

To adjust the flow on the MRF OTC Compact "O" Series Pneumatic Plastic Throttle Valve for Actuator using a screwdriver: 1. Ensure system pressure is within safe limits (≤10 bar) and actuator is in a safe, de-energized state. 2. Locate the screwdriver adjustment slot/head on the valve body (designed for easy adjustment). 3. Insert a suitable screwdriver into the adjustment slot. 4. Turn clockwise to reduce flow (throttle more) and counterclockwise to increase flow (open more). Make small incremental turns and wait between adjustments to allow the actuator to respond. 5. Test actuator speed/response after each adjustment; fine-tune until desired flow and timing are achieved. 6. If fitted, reinstall the protective cover to secure the adjustment and protect against damage or contamination. 7. Re-check for leaks, verify operation across the working temperature range (-10°C to +50°C), and confirm the valve functions correctly at system pressure. Use appropriate PPE and follow site safety procedures.
