Norgren P68F-NGC-PFA Dump Valve - IP65 Sealed Plug
Part Number: P68F-NGC-PFA
Quick Summary
Norgren P68F-NGC-PFA is a soft-start dump valve for controlling startup pressure in pneumatic machinery, including packaging, assembly, and tooling lines. Engineers frequently struggle with pressure spikes that stress cylinders, valves, and tooling, leading to unplanned downtime and longer setup times. Its IP65 protection and design support the European Machineries Directive and PUWER, helping you meet regulatory requirements during integration and upgrades. With a compact aluminium body, compatible yoke options, and high-flow capacity, the device delivers reliable startup control while protecting downstream circuits and reducing total cost of ownership. This combination delivers measurable business value, improving line uptime, accelerating time-to-market, and reducing energy consumption across pneumatic systems.

Feature: Medium and operating pressure range suited for standard compressed air systems and scalable start-up control. Business Impact: Enables consistent pressure ramp during machine start, reducing wear on valves and actuators. Application: Packaging lines and automated assembly cells benefit from smoother transitions and fewer faults. Feature: Solenoid pilot with spring return and 3/2 valve operation. Business Impact: Delivers precise, deterministic actuation with simple wiring, lowering integration risk and startup time. Application: Any automation loop requiring fast, repeatable pressure release in tight cycles. Feature: High flow capacity (147 dm3/sec / 312 scfm) and aluminium body. Business Impact: Supports larger downstream demand without bottlenecks, improving cycle times and energy efficiency. Application: High-throughput machining, grippers, and palletising lines. Feature: Elastomer seals in nitrile and IP65 rating with sealed plug. Business Impact: Enables wash-down and dirty-environment use without compromising performance, reducing maintenance cycles. Application: Industrial environments with exposure to dust, moisture and oils. Feature: Without Yoke port option and compatibility with Y68A yoke assemblies plus wall bracket availability. Business Impact: Simplifies installation, reduces space claims, and lowers total cost of ownership through flexible mounting. Application: Retrofit and new-build installations in compact automation cells. Feature: 3/2 valve operation combined with 3–10 bar range and 44–145 psi. Business Impact: Provides adaptable startup pressure control across different tool and cylinder configurations, ensuring safe ramping. Application: General-purpose pneumatic lines in machine tools and packaging automation. Insight: The Olympian Plus lineage adds proven reliability and serviceability in harsh factory conditions, with a focus on predictable response times and easy field maintenance. This translates to lower spare-part inventories and faster repair cycles for OEMs and end users.

FAQs
The P68F-NGC-PFA is designed for flexible mounting. For without-yoke installations, consider using the Y68A-N1N or Y68A-N2N yoke assemblies where compatible, and secure the unit with the 18-001-979 wall bracket if space and alignment require wall-mounting. Ensure proper screw torque and confirm seal integrity for IP65 performance.
A 3/2 valve offers three-port, two-position control, enabling a defined pressurization path and rapid exhaust when starting or stopping. This reduces startup surge, protects downstream tools, and shortens setup times. In high-cycle environments, the predictable response minimizes irregular cycling and improves line throughput.
Yes. The product supports regulatory-aligned design by providing controlled startup, robust IP65 protection for wash-down environments, and documentation alignment with European machinery directives. This helps when designing new equipment or upgrading existing lines to meet PUWER requirements while maintaining CE-related expectations.
The valve uses aluminium body construction with nitrile elastomer seals, offering solid durability in typical factory environments. Regular checks should verify seal integrity and clean ports to maintain IP65 performance. Availability of spares and service guidance from Norgren reduces downtime, while modular yoke options simplify part replacement without full unit rework.
Customers typically see reduced start-up shocks, longer tool life, and lower maintenance frequency due to smoother ramping. The high flow capacity supports rapid downstream actuation without oversize components, contributing to energy efficiency and higher machine uptime. Flexible mounting and compatible accessories also cut installation time and total cost of ownership.
