Norgren P68F-BGB-NNN Soft Start Dump Valve - 3-17 bar
Part Number: P68F-BGB-NNN
Quick Summary
The Norgren P68F-BGB-NNN soft start dump valve is designed to deliver smooth startup control for pneumatic systems in industrial machinery. Operators often contend with pressure spikes that cause wear, downtime, and inconsistent cycle times. This valve supports compliance with the European Machineries Directive and PUWER by enabling a controlled ramp of downstream pressure and safer start-up sequences. With its aluminium body, high-flow capability, and reliable air-pilot/spring actuation, it offers predictable performance, easy integration with G1-1/2 ports, and compatibility with Rc1/8 gauge ports in packaging, automation, and material handling applications.

FAQs
The valve features a G1-1/2 main port with Rc1/8 gauge port for monitoring. It operates as a 3/2 valve with air pilot/spring return actuation, making it compatible with standard pneumatic circuits and typical mounting patterns found on packaging and automation equipment. Proper orientation and mounting hardware should follow the installer’s guidelines to ensure reliable actuation.
Operating pressure range is 3 to 17 bar (44 to 246 psi). The valve provides a forward flow capacity of 147 dm3/sec (312 scfm), enabling rapid but controlled pressure development downstream. It weighs 3.05 kg with an aluminium body and nitrile elastomer seals, suitable for industrial environments.
Yes. The P68F-BGB-NNN is designed for high-demand pneumatic systems used in packaging, automation, and material handling. Its soft-start feature reduces start-up shocks, while the high-flow capacity supports quick, efficient line cycles. The G1-1/2 port size and Rc1/8 gauge port provide flexible integration with common industry fittings.
The valve supports regulatory compliance by enabling controlled pressure ramping to assist European Machineries Directive adherence and PUWER-related safe operation. Although explicit certifications aren’t listed, its design emphasizes safe startup sequences, robust materials, and predictable performance suitable for regulated manufacturing environments.
Durable aluminium construction with nitrile elastomer seals reduces wear and replacement needs, contributing to lower maintenance costs. The combination of a soft-start function and high-flow capability shortens cycle times, improving overall equipment uptime and return on investment for automated lines and continuous production processes.
