Is the Pneumatic check valve VNR L (thread - hose) with NBR O-ring suitable for filtered compressed air at 12 bar and -20Â°C to +60Â°C?

Yes. Pneumatic check valve VNR L (thread - hose) is suitable for filtered compressed air at up to 12 bar and in the temperature range â20Â°C to +60Â°C. The product specs state: working pressure 12 bar, NBR (nitrile) sealing, operating temperature â20Â°C to +60Â°C, and compatibility with filtered compressed air (oiled or non-oiled). Ensure the air is properly filtered and that NBR compatibility with any specific oil additives or contaminants present in your system is acceptable; otherwise select a different elastomer. Also verify correct installation (thread-to-hose connection and wall mounting) for leak-free operation.

Does the Pneumatic check valve VNR L (thread - hose) with NBR O-ring work reliably when air is oiled or non-oiled at 12 bar and -20Â°C to +60Â°C?

Yes. The Pneumatic check valve VNR L (thread - hose) with an NBR O-ring is specified for filtered compressed air, both oiled and nonâoiled, at a working pressure up to 12 bar and an operating temperature range of â20 Â°C to +60 Â°C. NBR (Nitrile) seals are compatible with typical lubricated and nonâlubricated compressed air in that temperature range, so when installed and used under the stated conditions (filtered air, max 12 bar, â20â¦+60 Â°C), the valve should work reliably. Ensure correct mounting, compatibility with any specific oil type, and regular inspection for wear or contamination to maintain performance.

Can the Pneumatic check valve VNR L (thread - hose) with NBR O-ring be mounted on walls using its provided holes?

Yes. The Pneumatic check valve VNR L (thread - hose) with NBR O-ring can be wall-mounted using its provided holes. The product description explicitly states it comes âwith holes for wall mounting.â Ensure the installation follows these guidelines: - Mounting surface and fasteners: use a rigid, flat surface and appropriate screws/bolts sized to the valveâs mounting holes and the installation substrate to prevent deformation or loosening under vibration or pressure cycles. - Orientation and accessibility: mount so flow direction and the valveâs threaded and hose connections are accessible for piping, sealing (NBR O-ring), and maintenance. - Pressure and temperature limits: do not exceed the working pressure (12 bar) or the operating temperature range (â20Â°C to +60Â°C). - Media compatibility and filtration: use only filtered compressed air (oiled or non-oiled) as specified to avoid contamination that could impair valve function. - Sealing and torque: when connecting threaded and hose fittings, follow recommended torque values and ensure the NBR O-ring is seated correctly to maintain leak-tightness. - Vibration and support: if installations are subject to significant vibration or dynamic loads, provide additional support to piping to avoid transferring loads to the valve body or mounting points. Following these precautions, the Pneumatic check valve VNR L (thread - hose) with NBR O-ring is suitable for wall mounting using its provided holes.
