Can the MRF NTB plastic pneumatic throttling valve, COMPACT "N" series be secured against accidental adjustment after setting with the locking nut?

Yes. The MRF NTB plastic pneumatic throttling valve, COMPACT "N" series can be secured against accidental adjustment after setting by using the integrated locking nut. The valve allows adjustment via a control knob and/or screwdriver and the locking nut can be tightened once the desired flow rate is set, preventing unintended changes during operation. This feature applies across available sizes (M5, 1/8", 1/4", 3/8", 1/2") and is suitable for use up to 10 bar and temperatures from -10Â°C to +50Â°C.

How do I adjust the flow direction settings on the MRF NTB plastic pneumatic throttling valve, COMPACT "N" series?

To adjust flow direction settings on the MRF NTB plastic pneumatic throttling valve, COMPACT "N" series: use the control knob (or screwdriver slot) on the valve to change the throttling position-turning it clockwise reduces flow, counterclockwise increases flow-for both filling and venting directions (simultaneous regulation). Once the desired flow/direction is set, secure it with the locking nut to prevent movement. For hose connection/disassembly use the plug connection. The valve is available in M5, 1/8", 1/4", 3/8", 1/2", supports up to 10 bar, operates from â10Â°C to +50Â°C and is made of plastic.

Does the MRF NTB plastic pneumatic throttling valve, COMPACT "N" series require specific tools for disassembly of hoses via the plug connection?

No, the MRF NTB plastic pneumatic throttling valve, COMPACT "N" series does not require special tools for disassembly of hoses via the plug connection. The valve is equipped with a push-in (plug) connection designed for easy manual release of pneumatic hosesâtypically by pressing the collet and pulling the tubing out. Standard hand operation is sufficient; only common tools (e.g., a cutter to trim tubing or a screwdriver for the control knob if adjustment locking nut is tightened) may be needed for maintenance or adjustment, but no dedicated or proprietary disassembly tool is required.
