Can the MRF N/C brass pneumatic throttling and check valve for actuator directly mount to actuator ports and still allow easy hose disconnection via the plug-in coupling?

Yes. The MRF N/C brass pneumatic throttling and check valve, for actuator is designed for direct mounting to actuator ports and still allows easy hose disconnection via its plugâin coupling. Its compact nickelâplated brass body and integrated plugâin coupling permit direct installation at the actuator connection while preserving quick disconnect capability for pneumatic hoses. The valve provides adjustable flow control (knob/screw with locking nut) and checkâvalve function, supports up to 10 bar (nominal flow specified at 6.3 bar), and operates from â10 Â°C to +70 Â°C, so it is suitable for actuator mounting without sacrificing ease of hose disassembly.

Does the MRF N/C brass pneumatic throttling and check valve, for actuator, support different flow rates at 6.3 bar based on knob vs screwdriver adjustment?

Yes. The MRF N/C brass pneumatic throttling and check valve, for actuator supports different flow rates at 6.3 bar depending on whether you use the knob or the screwdriver for adjustment. The product description states adjustment change via a control knob and/or screwdriver and the specified nominal flow is given at 6.3 bar in the throttled direction. Both adjustment methods alter the throttling element position (and can be locked with the nut), so each setting corresponds to a different restricted or freer flow. The operating pressure (up to 10 bar), temperature range and body material do not change this behavior. the selected knob or screwdriver position determines the flow rate at 6.3 bar.

MRF N/C brass pneumatic throttling and check valve, for actuator

Q: How do I lock the adjustment on the MRF N/C brass pneumatic throttling and check valve for actuator to prevent accidental changes?

To lock the adjustment on the MRF N/C brass pneumatic throttling and check valve, for actuator: 1. Set the desired flow using the control knob or screwdriver in the throttling direction. 2. Tighten the integrated locking nut against the body to secure the control shaft and prevent rotation. 3. Confirm the setting by attempting a light turn of the knob; if it moves, re-tighten the locking nut. 4. For added security, after locking you may mark the nut/knob position with paint or a tamper-evident seal. Ensure system pressure is relieved or within safe limits before making adjustments.
