Norgren P68F-NGL-PAA Soft Start Dump Valve - IP65
Part Number: P68F-NGL-PAA
Quick Summary
Norgren P68F-NGL-PAA is a soft start dump valve for compressed air systems that smooth startup and protect downstream equipment. Engineers often struggle with inrush pressures that stress seals and shorten line life; this valve provides a controlled pressure rise. Designed to align with the European Machinery Directive CE compliance and PUWER requirements, it also features IP65 protection for harsh environments. Its compact aluminium body, high flow, and simple mounting translate to faster installation and longer equipment uptime. This combination delivers reliable pneumatic control for automation projects while minimizing downtime and maintenance costs.

Feature → Business Impact → Application: The P68F-NGL-PAA’s soft-start functionality delivers a controlled pressure rise during startup, reducing shock loads and sealing wear, which translates to extended component life and lower maintenance costs in busy production lines. This improves overall equipment effectiveness (OEE) and reduces unplanned downtime in packaging and automation cells. Application: Suitable for automated lines that require gentle startup of downstream flows to protect sensitive actuators and tooling. Feature → Business Impact → Application: With a 3 to 10 bar operating range and a flow of 147 dm3/s (312 scfm), the valve accommodates diverse plant air networks, enabling rapid integration into existing systems without excessive piping changes. This supports faster changeovers and scalable automation across multiple workstations. Application: General pneumatic control across manufacturing, presses, and pick-and-place equipment.Feature → Business Impact → Application: Solenoid pilot with spring return provides reliable, fail-safe actuation in remote control schemes, improving control integrity and safety interlocks. This reduces downstream faults and simplifies electrical design for machine builders. Application: Remote start sequences and safety-rated control loops in automated lines.Feature → Business Impact → Application: IP65 protection with sealed plug ensures dependable operation in washdown environments and harsh industrial spaces, minimizing ingress risk and downtime due to moisture or dust. Application: Food & beverage, packaging lines, and outdoor equipment where ruggedness matters.Feature → Business Impact → Application: Aluminium body with nitrile elastomer seals offers durability and chemical resistance while keeping weight manageable for easier installation and vibration resistance. Application: Long-life installations with frequent start-stop cycles and exposure to common industrial fluids. Feature → Business Impact → Application: Compatibility with Y68A yoke assemblies and wall bracket 18-001-979 enables flexible mounting options without duplicating hardware order complexity. Application: Retrofit projects or multi-station systems requiring quick, secure installation.

FAQs
The P68F-NGL-PAA is designed to work with Norgren Y68A-N1N and Y68A-N2N yoke assemblies, enabling straightforward mounting on common frames and machines. When retrofitting, remove existing valve hardware, attach the appropriate yoke, and secure with standard hardware. Use the 18-001-979 Wall Bracket for added rigidity and vibration resistance in compact layouts.
Operating pressure spans 3 to 10 bar (44 to 145 psi), and the valve delivers a forward flow of 147 dm3/s (312 scfm). This combination supports rapid startup sequencing while maintaining controlled downstream pressure. For upgrades, ensure your supply can sustain the peak flow and verify downstream components tolerate the startup profile.
Yes. The valve is designed to assist designers in meeting European Machinery Directive requirements and PUWER regulations by enabling controlled startup and safe system startup procedures. IP65 protection adds environmental resilience, and the dimensions, materials, and mounting options support compliant integration into established safety and maintenance programs.
Mounting can be performed using the included wall bracket 18-001-979 for secure, space-efficient installation. Yoke assemblies Y68A-6GN-N1N and Y68A-6GN-N2N are available to accommodate without-yoke port configurations, providing flexibility for retrofits or new builds. Both mounting paths support tidy cable routing and stable operation in demanding environments.
The aluminium body and nitrile elastomer seals deliver durability and resistance to typical industrial fluids, reducing wear. The solenoid pilot / spring return arrangement provides predictable actuation with low maintenance. IP65 protection minimizes ingress risk, lowering fault-related downtime and extending service intervals in challenging plants.
