Norgren P64F-4GL-PFA Olympian Plus dump valve - G1/2
Part Number: P64F-4GL-PFA
Quick Summary
The P64F-4GL-PFA is a soft start dump valve for controlled pneumatic start-up in automation lines. This design helps prevent downstream pressure spikes that can damage cylinders or disrupt production. It supports CE marking alignment with the European Machinery Directive and PUWER guidelines, helping engineers meet European safety standards. For system integrators, the valve delivers predictable ramping and safe shutdown while integrating with Norgren’s Olympian Plus ecosystem and compatible mounting accessories. In practice, adopting this valve reduces start-up transients, improves line reliability, and lowers lifecycle costs across standard compressed air applications.

FAQs
Yes. The P64F-4GL-PFA is designed for integration with common Norgren accessories, including 74504-50 wall brackets and Y64A-4GA yoke assemblies. It supports the Olympian Plus plug-in system and accessories like T64T-4GB-P1N, enabling straightforward retrofits and modular assemblies in existing pneumatic lines.
Key specs include medium: compressed air; operating pressure: 3–10 bar; port size: G1/2; valve operation: 3/2; actuation: solenoid pilot / spring return; flow: 57 dm3/sec (121 scfm); gauge port Rc1/8. These enable precise start-up control and fast venting for stable system pressure.
Best suited for automation lines and machine tools where controlled pressure ramp and safe start-up are critical. It protects downstream cylinders, reduces mechanical wear, and supports compliant start-up procedures in European machinery environments. Typical uses include packaging, pick-and-place, and transfer systems.
The P64F-4GL-PFA is designed to support European Machinery Directive compliance and PUWER-aligned safety practices. While it is built for robust factory use, verify your end-user regulatory requirements and mark CE-related considerations in your integration documentation and vendor qualifications.
The zinc alloy body and nitrile elastomer seals deliver durability in typical industrial environments, reducing leakages and maintenance cycles. Spare coils QM/48/13J/21 are available, and the valve integrates with common Norgren mountings and silencers such as MB004B for quieter operation, contributing to lower total cost of ownership.
