Norgren P64F-4GC-NFA Olympian Plus Soft Start Dump Valve - 3-10 bar
Part Number: P64F-4GC-NFA
Quick Summary
Norgren P64F-4GC-NFA is a soft start dump valve for controlled pneumatic startup in machinery. Designers often wrestle with pressure surges that stress cylinders and shorten equipment uptime. The design supports CE compliance under the European Machinery Directive and PUWER guidance to simplify approvals across European lines. Built for G1/2 ports and a 3–10 bar operating range, it enables safer starts and reliable control in automation lines. For procurement teams, the rugged zinc alloy body and nitrile elastomer seal translate to longer service life and predictable maintenance, reducing total cost of ownership.

Feature: High forward flow capacity with a 57 dm3/s (121 scfm) flow rating enables rapid yet controlled charging of downstream lines. Business Impact: Reduces startup time and cycle times while maintaining safe pressure ramp, improving line throughput. Application: Ideal for packaging equipment, clamping systems, and automation cells where fast, controlled venting is critical. Feature: Solenoid pilot / spring return actuation provides reliable, fail-safe control with straightforward PLC interfacing. Business Impact: Simplifies electrical wiring and enhances system safety by ensuring a defined off-state when unpowered. Application: Suitable for synchronous start sequences in serialized manufacturing processes and retrofit projects. Feature: G1/2 port size and Rc1/8 gauge port support flexible plumbing and easy integration into existing air networks. Business Impact: Minimize modification costs and enable rapid machine upgrade without large flow restrictions. Application: Common on small-to-mid sized Pneumatic lines in material handling and assembly equipment. Feature: Operating temperature range -20 to 50 °C (-4 to 149 °F) and compressed air medium provide durability in varied factory environments. Business Impact: Extends service life in harsh industrial settings, reducing maintenance downtime. Application: Suitable for outdoor or semi-enclosed panels and conveyors. Feature: Durable zinc alloy body and nitrile elastomer seals deliver robust performance with good chemical resistance. Business Impact: Lower replacement frequency and improved contamination tolerance. Application: Long-life components in OEM automation and aftermarket service scenarios. Feature: Wide range of accessories and mountings (T64T-4GB-P1N, 74504-50 wall bracket, Y64A-4GA-N2N/N1N yoke assemblies, MB004B silencer, QM/48/13J/21 spare coils) simplify installation and customization. Business Impact: Faster commissioning, quieter operation, and easier serviceability. Application: Integrated into compact control panels and modular automation setups.

FAQs
Yes. The P64F-4GC-NFA uses a G1/2 port and 3/2 valve operation, allowing straightforward integration with common PLC-controlled pneumatic circuits. It also pairs with standard accessories such as wall brackets (74504-50) and yoke assemblies (Y64A-4GA-N1N/N2N) to simplify mounting on existing frames.
The valve delivers a flow of 57 dm3/s (121 scfm) and operates within a 3 to 10 bar (43 to 145 psi) range. These specs enable rapid yet controlled charging of downstream lines, reducing startup stress on actuators and connected tooling.
Absolutely. The Olympian Plus design provides controlled pressure ramp during startup, which minimizes shocks to clamps and grippers, improves cycle times, and supports safe integration in packaging lines and automation cells.
The design is intended to support CE compliance under the European Machinery Directive and PUWER guidance, aiding regulatory approvals in European operations. Always verify your contract-specific requirements and install per local standards to ensure full compliance.
With a zinc alloy body and nitrile elastomer seals, the valve offers durability and resistance to typical factory contaminants, reducing replacement frequency. The combination of high flow, compact form, and easy mounting lowers downtime and maintenance costs, yielding a favorable total cost of ownership over its service life.
