FAQs
This model uses standard 3/8" PTF ports and a 1/8" gauge port, allowing straightforward integration with common fittings found in most automation and packaging lines. Its dimensions and mounting footprint are designed to fit compact spaces, making field retrofits and OEM integrations simpler without custom adapters.
The outlet pressure is adjustable from 0.3 to 4 bar (4 to 58 psi). The maximum inlet pressure is 20 bar, which provides a robust operating envelope for typical compressed air applications in automation, robotics, and material handling systems.
The push-to-lock adjusting knob includes a built-in tamper-resistant feature that reduces drift from vibration or inadvertent adjustments. This improves consistency, reduces unplanned downtime, and lowers maintenance costs in high-cycle or vibration-prone equipment such as conveyors and pick-and-place systems.
Yes. With an integrated gauge, compact form, and controlled relief function, this regulator supports reliable pressure regulation essential for precision actuation. The materials (acetal knob, diecast aluminium body, POM bonnet, nitrile elastomers) provide durability in demanding environments, contributing to consistent performance in automation, robotics, and packaging lines.
Install with the flush-mounted gauge visible for quick checks, use standard 3/8" PTF connections, and ensure the inlet pressure does not exceed 20 bar. Maintain operating temperature within -20 to 65 °C, and select compatible elastomer seals for the media. Regularly inspect the knurled knob and gauge for signs of wear to sustain accuracy and reduce downtime.
