FAQs
The P68F-6GC-PFA uses standard G3/4 porting for straightforward integration into existing pneumatic circuits. Recommended mounting options include wall brackets (e.g., 18-001-979) and yoke assemblies (Y68A-6GN-N1N / Y68A-6GN-N2N) to simplify alignment and service access. Use the RC1/8 gauge port for pressure sensing and ensure IP65-rated sealed connections for washdown environments.
The valve employs solenoid pilot actuation with a spring return, providing a reliable fail-safe response during power loss. This configuration enables deterministic start-up sequencing, reduces inadvertent release, and supports automated control strategies within standard PLC or motion-controller environments.
Yes. With a 3/2 valve configuration and a nominal flow of 147 dm3/s (312 scfm), the P68F-6GC-PFA delivers rapid downstream pressure relief and consistent startup behavior. This translates to shorter cycle times, improved line throughput, and reduced peak load on upstream compressors when integrated into high-volume applications.
The valve is IP65-rated with a sealed plug, suitable for protected external and washdown environments. It is designed to support European Machinery Directive compliance and PUWER regulatory considerations, helping users meet safety and equipment-use requirements in automated production.
By delivering controlled start-up, high-flow performance, and a rugged aluminium body with nitrile elastomer seals, the P68F-6GC-PFA reduces startup-related wear, minimizes unplanned downtime, and lowers maintenance costs. Its modular compatibility with Nip/Norgren accessories simplifies future upgrades and line expansions, driving long-term total cost of ownership savings.
