Norgren P68F-8GH-PPA Olympian Plus Dump Valve - IP65
Part Number: P68F-8GH-PPA
Quick Summary
P68F-8GH-PPA is a soft-start dump valve that provides controlled downstream pressure in pneumatic machinery. Engineers often face startup surges that stress downstream components and trigger non-conformance with regulatory requirements. It supports CE marking and European Machinery Directive compliance, helps PUWER compliance, and carries IP65 protection with a sealed plug for demanding environments. With a compact aluminium body, 3/2 valve compatibility, and high flow capacity, it integrates smoothly with Olympian Plus installations and standard pilot-signal controls. In practice, the unit reduces start-up time variance, minimizes wear, and lowers maintenance costs across packaging lines and automation cells.

FAQs
This valve uses a G1 port and 3/2 valve configuration, compatible with Olympian Plus plug-in assemblies and common pilot controls. For retrofit, pairing with Yoke assemblies (e.g., Y68A-8GN-N1N or N2N) and a T68H-8GB-B2N plug-in shut-off valve streamlines mounting. Ensure the gauge port Rc1/8 is properly sealed and use the IP65-sealed plug to maintain ingress protection. Documentation and CAD data are available for integration checks before procurement.
At 6 bar nominal pressure, the P68F-8GH-PPA delivers up to 147 dm3/sec (312 scfm) of downstream flow with a 3/2 valve arrangement, enabling rapid yet controlled pressure ramping. The solenoid pilot with spring return provides repeatable actuation, minimizing start-up surge. This translates to shorter cycle times and reduced wear on downstream actuators, even on high-demand packaging lines.
Yes. The valve’s fast, controlled pressure ramp is ideal for packaging lines, automation cells, and CNC equipment where startup surges can cause misfeeds or actuator stalls. Its IP65 rating and aluminium body offer durability in busy production environments, while the 3/2 configuration simplifies integration with existing control logic and pilot systems.
The P68F-8GH-PPA supports European Machinery Directive compliance and PUWER considerations, aiding machine safety and regulatory alignment. The IP65 rating with sealed plug provides environmental protection, helping maintain equipment integrity in dusty or damp environments, while CE-related design practices ease conformity assessment for new installations.
Durable aluminium body and nitrile elastomer seals minimize maintenance intervals, reducing downtime and replacement costs. The high-flow, controlled-start capability improves throughputs and reduces wear on downstream components, contributing to a favorable return on investment over equipment lifetimes, especially in high-cycle packaging and automation lines.
