Norgren P64S-NNC-N1N Valves - Soft Start Dump Valve
Part Number: P64S-NNC-N1N
Quick Summary
Norgren P64S-NNC-N1N soft start dump valve delivers a controlled pressure ramp for downstream cylinders in automation lines. Engineers frequently contend with sudden pressure surges during startup that can damage equipment and compromise operator safety. While explicit certifications like CE, SIL and IP ratings are essential for safety-critical devices, the data here focuses on operating range and materials to inform fit and longevity. The integrated monitored dump function and high flow capacity support reliable venting and rapid system reset, while the zinc alloy body and nitrile elastomer seals resist wear. With compatibility to standard yoke assemblies and compact mounting options, it helps reduce installation time and total cost of ownership.

FAQs
The P64S-NNC-N1N excels in pneumatic startup sequences where controlled pressure ramping protects downstream cylinders and operators. It is ideal for automation lines, clamping applications, and systems requiring a monitored vent to avoid sudden loads, while accommodating 3/2 valve configurations and standard mounting.
Before installation verify medium is clean compressed air, operating pressure supports 3–10 bar, and the port size is without a yoke. Confirm solenoid pilot with spring return actuation and 3/2 valve operation, plus compatible materials (zinc alloy body, nitrile seals) for your environment.
The monitored dump function provides a verifiable vent event, ensuring predictable depressurization and enabling traceability. This reduces startup risks, minimizes unexpected loads on downstream equipment, and supports faster, safer reset times after maintenance or faults.
Yes. The P64S-NNC-N1N is designed for compatibility with Norgren yoke assemblies such as Y64A-4GA-N2N/N3N/N1N, enabling straightforward retrofits and scalable integration with existing automation hardware and mounting options.
Routinely inspect seals and the solenoid coil for signs of wear or contamination. The nitrile elastomer seals and zinc alloy body are chosen for durability, but regular cleaning of the air path and verifying vent performance ensures consistent operation and minimizes unplanned downtime.
