Norgren P72F-2GC-PFA Excelon soft start dump valve - IP65
Part Number: P72F-2GC-PFA
Quick Summary
Norgren P72F-2GC-PFA Excelon soft start dump valve enables controlled downstream pressure during machine start-ups. Many machines suffer pressure surges at startup causing wear and downtime. This design supports CE conformity under the European Machineries Directive and IP65 with sealed plug. By integrating with compressed air systems and the Excelon line, it reduces risk, improves uptime, and supports compliant automation investments. Designed for engineers and procurement teams, it offers clear performance specs, robust materials, and straightforward installation. With a compact footprint, 3/2 valve operation, and 21 dm3/s flow, it fits demanding lines without added risk. This makes startup sequencing easier, enabling faster line commissioning and easier regulatory assurance.

Feature: Medium is compressed air; the body is a durable zinc alloy with synthetic elastomer seals. Business Impact: This combination delivers robust vibration resistance and long service life in harsh factory environments, reducing maintenance intervals and spare-part costs. Application: Ideal for high-cycle packaging lines and automated assembly where reliable startup sequencing matters. Feature: Operating pressure range from 3 to 10 bar with G1/4 ports and a 3/2 valve configuration; actuation by a solenoid pilot with spring return. Business Impact: Enables precise, repeatable venting and fail-safe shutoff in power-down scenarios, while supporting direct PLC control and common 24 V signals. Application: Start-up isolation and controlled pressure ramp in compressed-air lines for OEM equipment upgrades. Feature: Flow capacity about 21 dm3/s (45 scfm) and IP65 rated with sealed plug. Business Impact: High forward flow ensures quick venting and rapid response to startup conditions; IP65 protection reduces exposure to dust and moisture, boosting reliability. Application: Suitable for machine tools, conveyors, and washdown-adjacent stations. Feature: Compact dimensions (L 48.5 mm, W 85 mm, H 162 mm) and weight 0.91 kg; part of the P72F Excelon family by IMI Norgren. Business Impact: Easy retrofit and space-saving panel mounting; Czech-origin production supports local or regional sourcing and supply chain resilience. Application: OEM line upgrades for PUWER and Machinery Directive compliance while minimizing panel redesign.

FAQs
The valve uses a standard G1/4 port, 3/2 valve configuration, and a solenoid pilot with spring return, making it straightforward to wire to common 24 V DC PLC outputs. Its compact footprint (48.5 mm L x 85 mm W x 162 mm H) allows panel mounting in tight spaces, while the durable zinc alloy body and IP65 sealed plug enable reliable operation in typical factory environments.
Expect controlled downstream pressure ramp with a 3–10 bar operating range and a 21 dm3/s flow capacity, enabling gentle system pressurization and reduced surge. The 3/2 valve operation provides fast venting and reliable exhaust paths, while solenoid pilot actuation supports rapid, repeatable cycling aligned with line PLC timing.
Yes. The Excelon soft start dump valve supports CE-conformant design practices per the European Machineries Directive and PUWER adjacency by limiting startup energy spikes and enabling safer machine commissioning. Its IP65 rating with a sealed plug improves environmental protection, aiding compliance in dusty or wet shop-floor areas.
The valve carries an IP65 rating (with sealed plug) for protection against dust and water exposure. It is part of the Excelon series by IMI Norgren, with the country of origin listed as Czechia, reflecting its regional manufacturing and supply chain considerations.
Upgrading delivers measurable ROI through reduced startup surges, extended component life of downstream equipment, and faster line commissioning. The valve’s robust build, easy retrofit, and compatibility with common control signals minimize downtime during installation, while its compliance features help avoid regulatory delays on new or retrofitted machinery.
