Norgren P72F-2GC-PFN Soft Start Dump Valve - IP65
Part Number: P72F-2GC-PFN
Quick Summary
Soft start dump valve P72F-2GC-PFN delivers controlled startup pressure for pneumatic drives in packaging and automation lines. Manufacturers often face startup shocks, valve chatter, and compliance challenges when bringing new equipment online. This Excelon valve supports CE conformity for European Machinery Directive compliance and IP65 protection for demanding environments, and it aligns with PUWER considerations to keep equipment safe and operable. By offering a solenoid pilot with spring return, a 3/2 valve operation, and a generous downstream flow, it minimizes downstream pressure spikes while maximizing cycle efficiency. Its compact G1/4 port design and compatibility with standard 22 mm coil connectors streamline installation and retrofit, reducing wiring costs and downtime.

FAQs
Mount the valve using Quikclamp options 4214-51 for wall mounting or 4214-52 for wall-mounted brackets. Use the G1/4 port for the pneumatic supply and connect to standard 22 mm coil connectors (M/P24121/1 or M/P24121/2). Ensure the supply is within 3–10 bar and keep the enclosure rated to IP65 for best protection. The solenoid pilot with spring return simplifies wiring to typical PLC outputs; consult the installation guide for wiring diagrams and coil polarity.
The P72F-2GC-PFN operates from 3 to 10 bar (44–145 psi) with a downstream flow of 21 dm3/s (45 scfm). It uses a G1/4 port and implements a 3/2 valve arrangement with solenoid pilot and spring return, enabling predictable startup behavior for pneumatic cylinders and actuators.
Yes. The Excelon P72F-2GC-PFN is designed to support European Machinery Directive compliance and PUWER considerations by enabling controlled startup sequences that minimize shocks and chatter, reducing the risk of non-compliance in automated equipment while improving overall safety and performance.
The valve carries IP65 protection for dust and water ingress and features a zinc alloy body with synthetic elastomer seals. This combination provides robust durability in harsh industrial environments and contributes to reliable long-term operation without frequent enclosure modifications.
Accessories include MB002B quietaire silencers for R1/4 connections, spare 22 mm electrical coil connectors (M/P24121/1 and M/P24121/2), and Quikclamp mounting options (4214-51 and 4214-52). These enable quieter operation, straightforward retrofits, and tidy panel integration with standard 22 mm coil coils.
