FAQs
The regulator is designed for inline installation or modular configurations, enabling compact layouts and easy retrofits in control panels or automated lines. Gauge port Rc1/8 allows test connections, and standard mountings ease integration with existing infrastructure.
Maximum inlet pressure is 20 bar, with an adjustable outlet range of 0.3 to 4 bar (4 to 58 psi). The unit is a non-relieving regulator, suitable for stable downstream pressure under normal operation in pneumatic systems.
Yes. The knob is push-to-lock, and there is an available tamper-resistant accessory (4355-51) to prevent accidental adjustments, beneficial in high-changeover environments or where process integrity must be maintained.
The body and bonnet are diecast aluminium, with an acetal resin knob and nitrile rubber elastomers. Operating temperature ranges from -34 to 80 °C (-29 to 176 °F), making it suitable for most factory air systems and standard climate conditions.
Ideal for general pneumatic control in automated lines, tool actuation, and inline pressure regulation where compact form factor, reliable pressure control, and easy maintenance are valuable. Its Excelon design supports inline or modular installations, reducing integration time in factory automation projects.
