Norgren P64F-4GD-PFA Olympian Dump Valve - 3-10 bar
Part Number: P64F-4GD-PFA
Quick Summary
The Norgren P64F-4GD-PFA is a compact dump valve that soft-starts and dumps pressure during machine startup. Engineers routinely contend with startup pressure spikes that can cause actuator chatter, accelerate wear, and increase downtime. It supports CE marking under the European Machinery Directive and PUWER compliance, with a rugged zinc alloy body and nitrile elastomer seals. By pairing precise flow control with straightforward integration to standard Norgren accessories, this valve delivers reliable startup protection and predictable performance in pneumatic circuits.

Spare Coils
Soft-start and dump action reduces downstream pressure surge at startup, protecting cylinders, valves, and sensors, which lowers wear and maintenance costs in automated lines. This translates to shorter commissioning times and higher equipment availability in packaging, automation, and manufacturing cells. The valve’s high flow capacity—57 dm3/sec (121 scfm)—ensures rapid, controlled ramping without sacrificing control precision, supporting fast cycle times on demanding machines. Built to endure, its zinc alloy body and nitrile elastomer seals deliver durability in tough plant environments while resisting typical compressor lubricants and debris. The integrated gauge port Rc1/8 enables on-site diagnostics and quick fault isolation, while the solenoid pilot/spring return actuation and 3/2 valve configuration simplify wiring and control logic. Compatibility with T64T-4GB-P1N shut-off valves, wall brackets (74504-50), and accessories like silencers MB004B and spare coils QM/48/13J/21 streamlines installation and future upgrades. This cohesive package reduces lifecycle costs, improves compliance readiness, and supports scalable automation deployments.
