Norgren P68F-6GH-NPN Dump Valve - IP65
Part Number: P68F-6GH-NPN
Quick Summary
Norgren P68F-6GH-NPN is a soft start dump valve for controlled downstream pressure in automated systems. Engineers often battle startup transients that can spike downstream regulators and compromise cycle times. This design helps machine builders meet European Machinery Directive requirements, supports PUWER compliance, and delivers IP65 protection with a sealed plug for dust and wash-down environments. As part of the Olympian Plus family, it combines high flow capability with precise control, enabling faster startups and reduced energy waste. By integrating this pneumatic valve, facilities can improve system reliability while maintaining regulatory alignment and simplifying procurement with a single, compatible solution for compressed air circuits.

FAQs
The valve is designed for panel or wall mounting and uses standard porting (G3/4) with a gauge port Rc1/8. Install with IP65-sealed plug for dust and wash-down environments, and consider available wall brackets (e.g., 18-001-979 or 74504-50) to simplify alignment and conduit routing.
Actuation is solenoid pilot with spring return. Compatibility is enhanced by standard accessory options such as the M/P19063 electrical plug with cable gland. Ensure control electronics support typical PLC outputs and that the valve is wired to provide a safe, fail-safe de-energize operation when required.
Yes. The valve supports compliance by enabling a controlled startup sequence that helps meet the European Machinery Directive and PUWER requirements, reducing startup-related risk and facilitating regulator-friendly machine design.
Operating pressure is 3 to 10 bar with a high forward flow capacity of 147 dm3/sec (312 scfm). The valve configuration is 3/2, suitable for controlled downstream pressure during startup in compressed air systems.
The body is aluminium with nitrile elastomer seals, offering a balanced combination of weight and durability. It carries IP65 protection with a sealed plug, making it suitable for dusty and wash-down environments typical in packaging, automotive, and process industries.
