The P68F-6GC-PFN uses a solenoid pilot / spring return actuation to provide a controlled soft-start, which reduces downstream shock and inrush current. Business impact: longer life for cylinders and conveyors, lower maintenance costs, and safer machine starts in high-cycle environments. Application: packaging lines and automation cells benefit from smoother acceleration and reduced wear on critical components. The valve delivers a high flow capacity of 147 dm3/sec (312 scfm), enabling rapid pressure relief during startup while preserving system stability. Business impact: shorter cycle times and improved throughput in high-demand processes. Application: presses and transfer lines gain faster, more reliable startup sequences. The aluminium body with nitrile elastomer seals delivers rugged durability in dirty or washdown environments. Business impact: fewer field replacements and lower total cost of ownership. Application: factory floors and outdoor installations where IP65 protection matters. The combination of G3/4 port size, Rc1/8 gauge port, and 3/2 valve operation offers flexible integration. Business impact: easy retrofit, straightforward commissioning, and compatibility with existing pneumatic architectures. Application: OEM equipment and modernization projects. The product supports compliance and risk reduction through its IP65 sealing and European Machinery Directive alignment. Business impact: smoother regulatory qualification, safer operation, and reduced risk of non-conformant deployments. Application: general-purpose automation across multiple industries.

FAQs
Install the valve in a current pneumatic circuit by mounting the body for a convenient orientation, connect the G3/4 port to the main supply and the downstream line, and route the pilot signal through Rc1/8 gauge ports. The solenoid pilot / spring return actuation simplifies retrofit with existing 3/2 plug-in systems, while the IP65 sealed plug provides reliable protection in dusty or damp environments. Confirm electrical compatibility and proper wiring to ensure safe operation and consistent performance. Expect reduced startup shocks and smoother operation once wired correctly.
The P68F-6GC-PFN operates from 3 to 10 bar (44 to 145 psi) and offers a high relief flow of 147 dm3/sec (312 scfm). This combination supports rapid pressure build and controlled dump during startup without compromising downstream safety. Its 3/2 valve configuration enables straightforward control of pneumatic actuators, while G3/4 port sizing ensures compatibility with common industrial manifolds and tubing. Use within its specified range to maintain predictable performance and longevity.
Yes. The P68F-6GC-PFN helps engineers meet regulatory expectations by delivering controlled startup and pressure management aligned with European Machinery Directive requirements, supporting CE-compliant machine design. PUWER considerations are addressed through reduced startup shock and safer equipment behavior, contributing to safer operation and easier audits. The IP65 sealing further enhances suitability for harsh and washdown environments found in regulated industries, reinforcing compliance in real-world installations.
Commonly used accessories include the T68H-6GB-B2N plug-in shut-off valve for modular control, Yoke assemblies (Y68A-6GN-N1N, Y68A-6GN-N2N) for secure mounting, and a Wall Bracket (18-001-979) for fixed installation. Silencers like MB008B can reduce noise in compact lines. These components improve installation flexibility, serviceability, and vibration control, enabling cleaner integration in OEM equipment and retrofit projects.
The valve’s aluminium body and nitrile elastomer seals offer durability and resistance to typical factory environments, reducing component replacements and service intervals. The soft-start feature lowers mechanical wear and energy spikes, contributing to lower maintenance costs and longer asset life. In high-cycle applications, the combination of compliant operation and high flow can shorten startup times and boost overall equipment availability, delivering clear ROI over time.
