Can the MRF NMC Compact "N" Series Brass Pneumatic Throttle & Check Valve for Actuator be installed directly on different actuator types without additional fittings?

Yes — the MRF NMC Compact "N" Series Brass Pneumatic Throttle & Check Valve for Actuator is designed for direct installation in actuator ports. Its compact design and integrated plug-in coupling make it suitable for mounting straight into actuator connections without the need for additional fittings, provided the actuator port thread/size matches one of the available valve sizes (M5, 1/8″, 1/4″, 3/8″, 1/2″). It supports pressures up to 10 bar and temperatures -10°C to +70°C, and its nickel-plated brass construction ensures durability and corrosion resistance for industrial use. Note: Always confirm thread type and size compatibility with the actuator and ensure proper sealing (e.g., PTFE tape or compatible sealant) where required.

Q: How do I adjust flow on the MRF NMC Compact "N" Series Brass Pneumatic Throttle & Check Valve for Actuator and lock the setting for long-term use?

To adjust flow on the MRF NMC Compact "N" Series Brass Pneumatic Throttle & Check Valve for Actuator and lock the setting for long-term use: 1. Ensure system pressure is within limits (≤10 bar) and actuator is in a safe position. 2. If fitted, detach the plug-in coupling to relieve hose tension or for easier access. 3. Use the control knob or a screwdriver in the adjustment slot to set the desired flow. Turn slowly while observing actuator speed or a flow/pressure indicator until the required response is achieved. 4. Once the correct flow is reached, secure the setting by tightening the built-in locking nut against the knob or adjustment stem. Use an appropriate spanner to ensure a firm lock without over-tightening. 5. Reconnect the plug-in coupling if removed, cycle the actuator a few times to confirm stable performance, and check for leaks. 6. For long-term reliability, verify the lock periodically and keep the valve within specified temperature range (−10°C to +70°C).
