FAQs

Install the regulator with the 3/8 inch NPT port connected to the pressurized supply and thread sealed using appropriate PTFE tape or thread sealant. Connect the 1/8 inch gauge port to the pressure instrument or test point as required. Verify no cross‑threading and tighten to standard torque values to avoid leaks.
The regulator provides an adjustable outlet pressure from 0.3 to 4 bar (4 to 58 psi) and supports a maximum inlet pressure of up to 20 bar. This ensures stable downstream pressure across typical pneumatic loads while tolerating brief inlet spikes.
Yes, it is part of the Excelon Plus family and designed for compatibility with standard air systems. It features a diecast aluminum body, an acetal bonnet/knob, and nitrile elastomer seals, delivering durability in industrial environments.
Typical expectations include CE compliance for European installations and robust protection considerations (IP ratings) dependent on enclosure and installation. SIL requirements are determined by the overall safety system, not solely by the regulator itself.
The tamper‑resistant knob reduces drift from accidental changes, lowering rework. The compact, lightweight design simplifies installations, and durable materials extend service life, reducing replacement costs and downtime. Overall, expect steadier process performance and faster line uptime.
