FAQs
The P72F-2GC-PEN is designed for the Excelon 72 series and uses a G1/4 port to fit standard pneumatic manifolds. It supports a 3/2 valve configuration and solenoid pilot with spring return, making it straightforward to retrofit into existing Norgren configurations without extensive plumbing changes. This compatibility extends to common compressed air circuits used in manufacturing, packaging, and automation cells.
It provides a controlled pressure ramp during startup, preventing shock loading and reducing downstream wear. The 3/2 valve with a 21 dm3/sec flow capacity delivers a rapid yet smooth actuation sequence, enabling faster cycle times while maintaining system safety. This translates to fewer hydraulic spikes, reduced product rejects, and improved line uptime.
Yes. The Excelon soft start dump valve supports CE compliance under the European Machinery Directive and helps manufacturers meet PUWER obligations by enabling safer, more predictable equipment startup. The unit’s design and documentation align with European safety standards, facilitating regulatory audits and compliance reviews for automated production lines.
Plan for a compact mounting footprint using the G1/4 port and ensure proper electrical supply to the solenoid coil. The modular nature of the Excelon 72 ecosystem allows straightforward wiring to spare coils (QM/48/12J/21) and compatibility with accessories like T72T-2GA-P1N and porting blocks (4216-52). Verify ambient temperature (-20 to 50 °C) and pressure range (3-10 bar) to match your application.
The P72F-2GC-PEN reduces startup wear and energy waste by delivering a controlled ramp, which lowers maintenance costs and extends component life. Spare coils and silencers, along with the existing Excelon modular ecosystem, enable easy preventive maintenance and quick field service. In high-cycle lines, the predictable startup behavior also improves overall uptime and production efficiency.
