Festo LR Series Pneumatic Regulator G 1/2 G G

This pneumatic regulator controls and stabilises supply pressure in compressed air systems, providing adjustable downstream pressure for industrial automation and pneumatic equipment. Built for routine workshop and plant use, it connects via standard G-thread ports and operates across a typical industrial temperature range.

• Maximum working pressure 16 bar for high-pressure applications
• Operates from -10 to 60°C for varied environmental conditions
• Die cast zinc body combined with NBR seals for durable sealing
• G 1/2 inlet and outlet thread compatibility for standard piping
• Conforms to ISO8573-1:2010 particulate and moisture classification for air quality
• RoHS conformity for material restriction compliance in installations

• Suitable for controlling actuators in factory automation lines
• Ideal for regulating feed to pneumatic tools and spray systems
• Used with air preparation units in compressed air networks
• Can be used for pressure control in testing rigs and benches
• Suitable for maintenance spares in system refurbishment projects

The principal wetted components are die cast zinc and NBR, offering corrosion resistance and straightforward seal replacement during service intervals.

Both ports use G-thread standardisation with G 1/2 size, enabling direct connection to common pneumatic fittings and reducing adaptor requirements.

The regulator aligns with ISO8573-1:2010 class descriptors, which informs the required upstream filtration to achieve specified particulate and moisture levels.

Continuous service must remain within the -10 to 60°C band to maintain seal integrity and consistent pressure regulation.
