SMC 1 in Regulator - 1 Mpa, 1/8 in 20000L/min, G AR

This regulator controls and stabilises compressed Air pressure for industrial pneumatic systems, incorporating a backflow function and a square embedded pressure gauge with limit indicator for inline monitoring. It is designed for use where high flow capacity and adjustable pressure control are required, operating across typical workshop ambient and media temperatures without freezing.

• Up to 20000 L/min flow capacity for high-volume supply
• Pressure setting range 0.05 to 0.85 MPa for fine adjustment
• Maximum operating pressure 1 MPa to support robust systems
• Die-cast aluminium body for durable, lightweight installation
• 1 in port size with G thread for standard piping connections
• 1/8 in pressure gauge port for direct instrument mounting

• Suitable for machine tool pneumatic supply requiring large flow
• Ideal for control cabinets feeding multiple valves and actuators
• Used for Air preparation on assembly-line conveyors
• Can be used for pneumatic testing rigs needing adjustable pressure
• Used with instrumentation where panel-mounted gauge indication is needed

It operates with pressure medium temperatures from −5°C to +60°C, provided there is no freezing, and the ambient range matches these limits.

The integrated backflow feature prevents downstream depressurisation from forcing Air back into the regulator, helping maintain set pressure during directional flow changes.

The unit uses a relieving exhaust mechanism that vents excess downstream pressure to atmosphere when the set Value is lowered.

The device is rated for a proof pressure of 1.5 MPa for pressure integrity verification procedures.
