FAQs
This valve supports standard G3/8 piping and is compatible with common mounting and connection accessories. For retrofit setups, you can pair it with M/P24121/1 or M/P24121/2 spare coil connectors, and it accepts Quikclamp 4214-51 for quick panel mounting. Silencer integration via MB002B is available to manage noise in open-loop systems.
Key specs include a 3/2 valve operation, 3–10 bar operating pressure, a medium of compressed air, port size G3/8, and a flow of 21 dm3/sec (45 scfm). Actuation is solenoid pilot with spring return, enabling reliable actuation and fail-safe operation in power loss scenarios.
Yes. The Excelon P72F-3GC-PFN supports compliance with the European Machineries Directive and PUWER through controlled startup behavior and robust IP65 protection with a sealed plug, reducing risk during commissioning and in daily operation. Its design and materials are chosen to meet stringent industrial safety expectations.
Its rugged zinc alloy body and synthetic elastomer seals provide durable performance with low leakage and long service life. The reliable soft-start reduces mechanical wear and downtime, while modular compatibility with standard accessories simplifies spare parts planning and reduces maintenance costs over the lifecycle.
To optimize installation, use Quietaire MB002B silencers for noise control, T40M0500 or similar silencers, Quikclamp mounting 4214-51 for secure panels, and the T72T-3GA-P1N series shut-off valve for modular layouts. Spare 22mm electrical coil connectors M/P24121/1 and M/P24121/2 simplify wiring and future upgrades.
