Norgren P68F-NGL-PFN Dump Valve - IP65 sealed plug
Part Number: P68F-NGL-PFN
Quick Summary
Norgren P68F-NGL-PFN dump valve delivers a controlled startup pressure ramp for pneumatic systems used in automated manufacturing. This soft-start feature reduces start-up shocks and protects downstream actuators, improving reliability. It contributes to CE conformity for the Machinery Directive and PUWER compliance, plus IP65 protection. Combined with a robust aluminum body, it is well-suited for demanding industrial environments. In addition to delivering predictable cycle times, this solution supports scalable integration with existing controls and procurement, helping engineers optimize downtime and maintenance planning. Designed for the Olympian Plus family and compatible with standard Norgren yoke and mounting accessories, it enables faster commissioning and minimizes bespoke adaptations across lines. It also supports streamlined procurement and simpler maintenance planning across multiple facilities.

Soft-start control provides a controlled pressure ramp during machine start-up, reducing peak load on downstream cylinders and extending actuator life in conveyors, clamps, and presses. This translates to lower maintenance costs and fewer unexpected stoppages in high-cycle lines. Port Size Without Yoke offers installation flexibility and compactness, enabling easier integration into tight cabinet spaces and enabling quick retrofits with existing frames using the 18-001-979 wall bracket and Yoke assemblies. Actuation via Solenoid pilot / Spring return delivers control versatility, allowing seamless PLC compatibility and safe fail-safe behavior during power loss or system faults. The IP65 rating with a sealed plug minimizes ingress of dust and moisture, reducing field service visits and enhancing reliability in harsh workshops. High flow capacity of 147 dm3/sec (312 scfm) supports rapid venting and tight pressure control for startup sequences, improving cycle time consistency. The aluminum body and nitrile elastomer seals balance durability and chemical resistance, lowering replacement intervals in standard industrial environments. Regulatory compliance and compatibility are reinforced by CE/Machinery Directive alignment, PUWER support, and easy integration with Norgren accessories, simplifying design reviews and procurement workflows.

FAQs
The P68F-NGL-PFN supports wall mounting with the 18-001-979 bracket and is compatible with Yoke assemblies Y68A-6GN-N1N and Y68A-6GN-N2N. Port configuration is Without Yoke, offering flexible positioning in tight enclosures. For fastest commissioning, pair with Norgren mounting accessories and ensure correct electrical isolation for the solenoid pilot.
Operating pressure ranges from 3 to 10 bar (44 to 145 psi). The valve provides a flow of 147 dm3/sec (312 scfm), enabling rapid venting and controlled ramping to minimize downstream shock during start-up of actuators.
Ideal for machine start-up sequences in pick-and-place, packaging lines, clamping assemblies, conveyors, and presses. The soft-start behavior reduces mechanical and electrical stress, improving uptime, component life, and cycle time consistency in automated manufacturing environments.
It offers CE conformity aligned with the European Machinery Directive and PUWER considerations, plus IP65 protection with a sealed plug for rugged environments. This combination simplifies regulatory reviews and helps ensure compliant installations across multiple facilities.
Durable aluminum construction and nitrile elastomer seals reduce frequent replacements. The IP65 protection lowers field service visits, and the soft-start capability reduces wear on downstream devices, contributing to improved uptime and lower total cost of ownership over the equipment’s life.
