Can the MRF OMB Brass Pneumatic Throttle Valve, Compact "O" Series be used with lubricated air or gases other than compressed air?

MRF OMB Brass Pneumatic Throttle Valve, Compact "O" Series is described specifically for precise bidirectional flow control of compressed air. The specification does not mention suitability for lubricated air or other gases. Given its construction (nickel-plated brass), pressure rating (up to 10 bar) and temperature range (-10°C to +70°C), it may tolerate some variation in media, but without explicit manufacturer confirmation the valve should be assumed intended for dry compressed air only. Using lubricated air or other gases could affect performance, seal compatibility and safety. For approval to use lubricated air or gases other than compressed air, consult the manufacturer or product datasheet for material compatibility, seal specifications and certifications before application.

Q: How do I install and adjust the MRF OMB Brass Pneumatic Throttle Valve, Compact "O" Series for bidirectional flow control?

MRF OMB Brass Pneumatic Throttle Valve, Compact "O" Series — Installation and Adjustment 1. Preparation - Select the correct size (M5, 1/8", 1/4", 3/8", 1/2") for your tubing and system pressure (max 10 bar). - Ensure system is depressurized and within operating temperature range (-10°C to +70°C). 2. Installation - Push-fit connection: insert pneumatic hose fully into the plug-in port until it seats firmly. - For threaded fittings, use appropriate sealant/tape and tighten to avoid leaks—do not overtighten to prevent damage to nickel-plated brass. - Mount valve in location allowing access to the adjustment screw and optional protective cover. - Re-pressurize system and check for leaks. 3. Adjustment for bidirectional flow control - The valve controls flow during both filling and venting—adjustments affect flow in both directions. - Use a screwdriver on the adjustment screw to set desired flow: - Turn clockwise to reduce flow (more restriction). - Turn counterclockwise to increase flow (less restriction). - Make small incremental turns, test system response, and fine-tune until the required flow/rate is achieved. 4. Safety and durability - Fit the optional protective cover after adjustment to protect the screw from accidental movement and wear. - Periodically inspect connections and re-check adjustment, especially under heavy use or high pressure. Follow these steps to achieve precise, reliable bidirectional flow control with the MRF OMB Brass Pneumatic Throttle Valve, Compact "O" Series.
