Feature: Inline or modular installation provides flexible integration into existing pneumatic networks → Business Impact: Minimizes installation time and service disruption, enabling faster line start-ups and easier retrofits in lean manufacturing environments. Application: Machine tool and packaging lines that require compact, adaptable regulators. Feature: Balanced valve design for precise pressure control → Business Impact: Delivers stable downstream pressure across varying load conditions, reducing part wear and process variability. Application: Automated assembly cells where consistent gripping and actuation are critical. Feature: Relieving model offers downstream pressure relief when the system is dead-ended → Business Impact: Enhances safety and protects downstream components from surge, lowering risk of pressure spikes. Application: Pneumatic circuits with potential dead-ends during cycle changes or shutdowns. Feature: Knob adjustment with tamper-resistant potential accessory → Business Impact: Prevents unauthorized changes, preserving setpoints and reducing maintenance calls. Application: Highly regulated or high-traffic manufacturing floors. Feature: G1/2 port size and Rc1/8 gauge port → Business Impact: Standardized connectivity simplifies integration with common manifolds and diagnostic tools. Application: Retrofit projects or new lines using common Norgren accessories like the 4316-52 Porting Block. Feature: Wide operating temperature range (-34 to 80 °C) and robust materials (die-cast aluminium body, acetal knob, nitrile elastomers) → Business Impact: Maintains performance in diverse environments, lowering replacement cycles. Application: Outdoor or in-damp environments where ambient conditions vary. Feature: 0.7–17 bar adjustable output with 20 bar max inlet → Business Impact: Broad regulation range supports multiple tooling pressures, improving process versatility and reducing spare parts inventory. Application: Conveyance and pick-and-place systems requiring adjustable pressure windows.
