FAQs
The P72F-2GL-PFA uses standard G1/4 port connections and integrates with the Excelon 72 family. Its 3/2 valve operation and zinc-alloy body are designed for seamless retrofit into existing Excelon manifolds, with compatible accessories like T72T-2GA-P1N and standard Quikclamp options to simplify installation and maintain system integrity.
Key specs include a 3 to 10 bar operating range, G1/4 port size, 3/2 valve operation, and a solenoid pilot with spring return. Flow is listed at 21 dm3/s (45 scfm), with medium as compressed air and a durable zinc alloy body designed for industrial use.
Yes. The valve is designed to assist machine designers in complying with the European Machinery Directive and PUWER by enabling controlled startup and reduced surge pressures, which supports safe, compliant machine operation in European environments.
Install the valve in a clean, dry compressed-air line with appropriate filtration. Use the Excelon 72 modular system accessories (such as the T72T-2GA-P1N shut-off valve) to create a compact, serviceable circuit. Consider adding a silencer like MB002B for noise reduction and ensure proper mounting to minimize vibration and wear.
Expected benefits include reduced startup surges, less wear on downstream components, shorter downtime due to fewer faults, and easier regulatory compliance paperwork. Accessory compatibility and modular design also lower installation time and spare-part costs, delivering a favorable total-cost-of-ownership over the valve’s service life.
