Can the Pneumatic Check Valve VNR L (Thread to Hose Connection) handle lubricated compressed air up to 12 bar without leakage?

Yes. The Pneumatic Check Valve VNR L (Thread to Hose Connection) is specified for working pressures up to 12 bar and is designed for use with filtered compressed air, both lubricated and non-lubricated. Its NBR sealing provides reliable resistance and long service life, and the O‑ring plus plug (thread–hose) connection ensures a secure, leak‑free installation when mounted properly. Operating temperature range −20°C to +60°C further supports its performance in typical industrial conditions.

Is the Pneumatic Check Valve VNR L (Thread to Hose Connection) suitable for outdoor use across its -20°C to +60°C temperature range without performance degradation?

Pneumatic Check Valve VNR L (Thread to Hose Connection) is suitable for outdoor use across its specified -20°C to +60°C operating temperature range without inherent performance degradation, provided the following conditions are met: - Ambient temperature stays within -20°C … +60°C. - Media is filtered compressed air (lubricated or non‑lubricated) as specified. - Exposure to direct weather (rain, UV, dust, corrosive atmospheres) is limited or mitigated—while the valve’s NBR sealing and construction provide durability, prolonged direct exposure to UV, salt spray, heavy contamination or aggressive chemicals can accelerate wear or sealing degradation. - Mechanical protection and proper installation (use of wall‑mounting holes, secure thread/hose connections) are applied to prevent physical damage and contamination ingress. - System pressure does not exceed the rated 12 bar. If outdoor conditions include prolonged sunlight, high humidity, salt air, heavy contamination or temperatures beyond the specified range, additional protective measures (enclosures, shielding, corrosion-resistant fittings, or alternative materials) are recommended to ensure long‑term performance.
