FAQs
The regulator supports both inline and modular installation, enabling quick integration into existing control panels or compact machine cells. With a G1/4 port and a 20 bar maximum inlet, it accommodates common factory air networks while maintaining a small footprint for space-constrained layouts.
Outlet pressure adjusts from 0.3 to 4 bar (4 to 58 psi), while the regulator is designed for a maximum inlet pressure of 20 bar. This combination supports precise downstream control across a wide range of pneumatic applications, from tooling actuation to regulator-driven cylinders.
This variant is specified as without a gauge, but it provides a gauge port (Rc1/8) for optional measurement connections when needed. This allows users to integrate an external gauge or sensor without altering the regulator’s core setpoint behavior.
The body is a zinc pressure diecast with an Acetal bonnet and knob, while the adjusting knob uses Acetal resin and elastomers are nitrile rubber. This combination delivers robustness under production-floor conditions and provides reliable sealing and wear resistance in compressed air systems.
Excelon delivers balanced valve dynamics for stable pressure, inline or modular installation to simplify retrofits, and a tamper-resistant knob to protect setpoints. These features translate to improved uptime, lower maintenance costs, and faster onboarding in automation projects.
