Norgren P68F-8GH-PZN Olympian Plus dump valve - 3/2
Part Number: P68F-8GH-PZN
Quick Summary
Olympian Plus soft start dump valve provides controlled pressure rise for safe startups in compressed air systems. Without proper start-up control, machines can suffer pressure spikes, excessive wear, and unpredictable downtime. It supports CE conformity under the European Machinery Directive and PUWER compliance, reducing regulatory risk and helping you meet essential safety requirements. By leveraging the Norgren P68F-8GH-PZN, you gain robust aluminum construction, reliable flow, and plug-in compatibility with Norgren accessories, enabling quicker installation and lower lifecycle costs. This translates to reduced commissioning time, predictable performance, and easier maintenance planning across production lines. Manufacturers also benefit from documented traceability and compatibility with modular valve families.

FAQs
The P68F-8GH-PZN uses a G1 port and Rc1/8 gauge port and is designed for compatibility with Norgren plug-in accessories such as T68H-8GB-B2N shut-off valves and Y68A yoke assemblies. For retrofit projects, mount using Yoke assemblies and secure with the wall bracket 18-001-979. Ensure solenoid pilot activation aligns with your control logic and that power supply matches the valve's coil requirements.
Expect a 3 to 10 bar operating range with a 3/2 valve configuration and a downstream flow of 147 dm3/s (312 scfm). The valve’s aluminum body and nitrile elastomer seals contribute to durability, while the solenoid pilot with spring return provides reliable fail-safe operation during power loss or control faults.
Yes. The P68F-8GH-PZN excels in packaging lines, automated cells, and other assembly processes where controlled startup is critical. Its high-flow capability supports rapid actuator cycling, and the robust build minimizes nuisance downtime, enabling higher overall line throughput and repeatable start sequences.
The valve is designed to assist compliance with CE marking under the European Machinery Directive and PUWER regulations by enabling controlled start-ups and predictable performance. Its modular design and traceable components simplify safety reviews, maintenance planning, and documentation required for regulatory audits.
The aluminum body and nitrile elastomer seals provide durability with reduced corrosion risk, lowering replacement frequency. Quick-plug compatibility and modular mounting options shorten maintenance time, while the reliable solenoid pilot reduces unintended actuation. Overall, expect lower downtime, easier part replacements, and a favorable return on investment through extended asset life.
