Is the Pneumatic throttling valve RFL L U valve version (hose - thread) suitable for use with oiled compressed air at 10 bar and temperatures from -20Â°C to +60Â°C?

Yes. The Pneumatic throttling valve RFL L U valve version (hose - thread) is suitable for use with oiled compressed air at 10 bar and temperatures between â20Â°C and +60Â°C. The product specification states a working pressure of 10 bar, an operating temperature range from â20Â°C to +60Â°C, and explicitly permits filtered compressed air that is oiled or non-oiled, so it meets your stated conditions.

Can the Pneumatic throttling valve RFL L U valve version (hose - thread) be used with filtered, non-oiled compressed air at varying flow rates up to 10 bar?

Yes. The Pneumatic throttling valve RFL L U valve version (hose - thread) can be used with filtered, non-oiled compressed air at varying flow rates up to 10 bar. Its specified working pressure is 10 bar, operating temperature â20Â°C to +60Â°C, and the medium compatibility explicitly includes filtered compressed air, oiled or non-oiled. Ensure proper installation of the plug-in inlet and threaded Oâring outlet, and maintain filtration to prevent contamination that could affect throttling performance.

Does the Pneumatic throttling valve RFL L U valve version (hose - thread) require an O-ring replacement schedule for 10 bar operation?

Yes. The Pneumatic throttling valve RFL L U valve version (hose - thread) uses an O-ring at the threaded outlet connection; because it operates at up to 10 bar with compressed air (filtered, oiled or nonâoiled) and across a temperature range of â20 Â°C to +60 Â°C, the O-ring is a pressureâloaded sealing element subject to mechanical wear, chemical exposure (lubricants, contaminants) and possible thermal aging. Therefore an Oâring inspection and replacement schedule is recommended. Suggested practice: - Inspect the Oâring visually at regular intervals (e.g., every 3â6 months under normal use). - Replace the Oâring proactively every 12 months or sooner if signs of hardening, cracking, flattening, extrusion, swelling, or leaks are detected, or if the valve is exposed to harsher conditions (continuous 10 bar cycles, high temperature swings, aggressive oils/contaminants). - Use the manufacturerâspecified Oâring material (compatible with compressed air, temperature range and lubrication) and proper lubrication/installation to avoid extrusion and damage. - After any disassembly for maintenance, always replace the Oâring prior to reassembly and pressure testing. Adjust inspection and replacement frequency based on actual duty cycle, environment, and leak history; critical or continuous highâpressure applications may require more frequent replacement.
