Norgren P64F-3GA-NNN Olympian Plus Dump Valve - G3/8
Part Number: P64F-3GA-NNN
Quick Summary
The P64F-3GA-NNN dump valve from Norgren provides controlled pressure release for pneumatic start-ups. Engineers often battle startup shocks and downstream pressure spikes that disrupt uptime and stress downstream components. It supports CE compliance under the European Machinery Directive and PUWER alignment, helping you meet regulatory requirements while avoiding redesign costs. Designed for G3/8 ports within a 3-10 bar range, it integrates with standard manifolds and 3/2 valve configurations to fit common machine layouts. With a rugged zinc alloy body and nitrile elastomer seals, this Norgren valve delivers predictable performance and lower maintenance across production lines.

Air pilot / spring-return actuation is a key feature. It delivers fail-safe operation that reduces unintended cylinder actuation and enhances operator safety. This supports reliable start-up sequences in automated lines. The valve provides high forward flow capacity (57 dm3/s / 121 scfm), resulting in rapid downstream pressure build-up and shorter cycle times when starting large actuators or lines in packaging and handling applications. Its 3/2 valve configuration simplifies control logic, enabling smoother integration with existing manifolds and control cabinets, which lowers engineering effort and installation risk. Operating pressure range of 3 to 10 bar and an ambient temperature span of -20 to 80 °C offers versatility across diverse environments, from clean rooms to harsher factory floors. The zinc alloy body and nitrile elastomer seals deliver durable performance under vibration, oil exposure, and routine maintenance cycles, reducing replacement costs and downtime. G3/8 port sizing and Rc1/8 gauge port support easy piping, monitoring, and diagnostics, making retrofits and new builds straightforward. The Olympian Plus series packaging and Germany-made craftsmanship provide consistent quality and long service life, supporting predictable maintenance budgets and spare-part planning.

FAQs
Install the valve as a direct replacement in your existing G3/8 port manifold, ensuring the air supply is clean and dry. Use the Rc1/8 gauge port to monitor downstream pressure during startup, and mount with compatible brackets such as 74504-50 or 18-001-978 for secure positioning. If silencing is required, MB004B silencers and related accessories can be added. Verify the 3/2 valve operation aligns with your control logic and ensure the actuation line is protected from contamination to maintain reliability.
Key specs include compressed air as the medium, operating temperature -20 to 80 °C, operating pressure 3 to 10 bar, G3/8 port size, Rc1/8 gauge port, and 3/2 valve operation. It uses an air pilot / spring-return actuation, provides a flow of 57 dm3/sec (121 scfm), and features a zinc alloy body with nitrile elastomer seals. The unit weighs approximately 1.94 kg and is part of the Olympian Plus series from IMI Norgren.
Yes. The valve is designed to support CE compliance under the European Machinery Directive and aligns with PUWER requirements, helping customers meet regulatory and safety obligations during machine design, installation, and modification. This reduces project risk when introducing new equipment and simplifies conformity assessments during audits and inspections.
Compatible accessories include MB008B quietaire silencers, T64T-3GB-P1N plug-in shut-off valves, M/P15737 electrical plug assemblies, and T68C-AGB-B2N shut-off valves. Mounting options include 74504-50 and 18-001-978 wall brackets. Silencers such as MB004B and T40B1800 can be used to manage noise. These options facilitate installation, retrofit projects, and integration with existing pneumatic networks.
The valve offers reliable, repeatable startup control which reduces pressure spikes and mechanical stress on downstream actuators, potentially lowering downtime and maintenance costs. Its robust zinc alloy body and nitrile seals support long service life in mixed production environments, while the standardized G3/8 connections simplify future part replacements and system expansions, contributing to a favorable total cost of ownership.
