Norgren P68F-NGH-NJN Dump Valve - IP65 Certified
Part Number: P68F-NGH-NJN
Quick Summary
The Norgren P68F-NGH-NJN dump valve provides soft-start pressure control for pneumatic systems in industrial automation. It helps prevent startup surges that can injure downstream components and shorten machinery life. CE-compliant under the European Machinery Directive and IP65 protected (with sealed plug), it supports reliable operation in demanding environments. This compact, high-flow valve enables compliant, efficient startup sequences for packaging lines, presses, and assembly cells, while offering robust performance in standard factory air systems and exposed installations.

Feature: Soft-start dump valve with controlled downstream pressure on startup → Business Impact: Reduces shock loading and wear on downstream actuators and airline plumbing, extending equipment life and lowering maintenance costs → Application: Ideal for automated presses, clamping stations, and transfer lines. Feature: High forward flow capacity (147 dm3/s, 312 scfm) → Business Impact: Faster cycle times and higher throughput with minimal pressure drop → Application: Conveyors, pick-and-place stations, and rapid-indexing tools. Feature: Operating pressure range of 3–10 bar (44–145 psi) → Business Impact: Flexible integration with common plant air systems without custom regulators → Application: General machine tools and pneumatic cylinders. Feature: IP65 rated with sealed plug → Business Impact: Reduced ingress-related downtime and easier washdown suitability → Application: Outdoor or wet/dust-prone environments in food, beverage, and packaging lines. Feature: Actuation by solenoid pilot / spring return; 3/2 valve → Business Impact: Simple, reliable electrical control with fast response and safe shutoff → Application: PLC-driven automation on control panels and machine safety logic. Feature: Aluminium body with nitrile elastomers → Business Impact: Lightweight, durable construction and long service life with chemical resistance → Application: Harsh factory floors and vibration-prone installations. Feature: Without Yoke port option and compatible accessories (Yoke assemblies, wall bracket, silencer) → Business Impact: Flexible mounting and turnkey installation → Application: Retrofit into existing machines with minimal downtime.

FAQs
This valve supports Yoke assemblies (Y68A-6GN-N1N and Y68A-6GN-N2N), a Wall Bracket (18-001-979), and a Quietaire silencer (MB008B). For retrofit projects, the port is without a yoke, so verify mounting clearance and stud pattern. Installation with the bracket and silencer minimizes vibration and noise in busy production environments.
Yes. The valve is designed to assist compliance with the European Machineries Directive and PUWER. Its IP65 rating and robust materials reduce risk of non-compliance due to ingress, while the solenoid pilot/spring return actuation aligns with standard PLC control schemes used in EU-based manufacturing.
Actuation is solenoid pilot with a spring return, driving a 3/2 valve. Normal operating pressure is 3–10 bar with a flow of 147 dm3/s (312 scfm). The body is aluminium and elastomers are nitrile rubber, ensuring reliable operation across standard factory air systems and typical control voltages used in industrial automation.
The valve operates from -20 to 50 °C (-4 to 122 °F) and features IP65 protection with sealed plug, making it suitable for dusty, damp, or washdown-prone environments commonly found on packaging lines, conveyors, and process equipment.
By delivering controlled startup, it minimizes surge loads, reduces wear and downtime, and enables faster cycle times with high flow capacity. Its compatibility with standard mounting, accessories, and control hardware simplifies installation, lowers installation costs, and helps ensure regulatory compliance across automation projects.
